Here are the types of flood lights with the different fixtures, designs, measurement tips, comparison to standard lights, and outdoor flood light bulb options.
There are countless activities you could never do outside after sundown in the past because darkness stopped you. That is why outdoor lighting has become a necessary part of everyday life. And, fortunately, a flood light has emerged, which is a man-made source of light that supplies you with a tremendous stream of outdoor illumination
Flood lights are typically used on massive sports fields or in locations that require a lot of light coming from a single lighting fixture. They are also frequently used in conjunction with surveillance cameras around the exterior of a home.
If you wish to learn more about how these fixtures are utilized and which bulbs are appropriate for certain purposes, you have come to the correct spot. This article will go through the different types of flood lights to help determine which is best for your needs.
What Is A Flood Light?
A flood light, as the name implies, is a broad-beamed, high-intensity type of lighting that actually floods the entire space with illumination. It is frequently used to brighten open-air sports fields while in an outdoor major sporting event conducted in low-light conditions.
In stage performances including festivals and musicals, more focused types are frequently utilized as stage lighting devices. Flood lights are necessary for the highest ranks of several professional sports to permit games to be arranged outside of daytime hours.
Midnight or nighttime games may be more convenient for viewers who have work or other obligations earlier in the day, and they allow for network telecasts during valuable prime time periods.
Flood lights play a crucial role in executing these types of big events. Moreover, the street lights that you usually see outdoors are also examples of flood lights. Flood lights operate by “flooding” an area with brightness, producing a larger spectrum of up to 120 degrees.
Such area light fixtures are ideal for illuminating wider outdoor areas while producing the same power or brightness production as a spotlight.
Standard Flood Light Fixture
A standard flood light fixture is essentially a simple flood ` fixture with no additional features, functions, or accessories. This indicates that the light fixture is made up of housing, a lightbulb, and electrical wiring to activate the lamp. Standard flood lights have no constraints and can be installed in virtually any location.
Other kinds of flood lights are derived from standard flood lights, which implies they are simply updated and tweaked versions of them. LED, CFL, or halogen lightbulbs are used in these fixtures. They are often housed in an aluminum or plastic enclosure and must be linked to a fuse box.
Standard flood lights provide between 1,600-4,000 lumens, and are best for illuminating smaller areas such as a walkway, staircase or back porch. See more types of outdoor light fixtures here.
Solar Flood Lights
A solar-driven flood light is a broad beam illumination that basically uses a solar panel and batteries to bathe a particular space with brightness. During the day, the solar panel charges the battery, but the charging process stops at night.
This allows the light to be completely self-sufficient and eliminates the need for it to be tethered to another source of power. They are available in a wide range of sizes, functionalities, and pricing levels.
Solar flood lights have lately gained popularity. Solar lighting fixtures normally include a built-in battery that is supplied by solar energy. This solar energy is obtained using a solar panel mounted to a light fixture.
Therefore, as we generally know, the energy from the sun is available for everyone, and solar flood lights enable you to save a lot of money on your electricity costs.
The lighting duration of solar flood light is, however, limited. The diameter and capacity of the solar screen and the flood light batteries are two specifications that determine how long solar lighting can illuminate.
Aside from that, solar flood lights are often capable of supplying lighting for less than an hour to all nighttime on bigger and more costly variants.
Multi-Directional Flood Lights
A multi-directional flood light is an excellent option for lighting huge spaces, like parking lots and factories, while using the least amount of lighting fixtures and masts.
This sort of lighting provides a plethora of settings. The light coverage is unrivaled for uncovered warehousing and stockpiling facilities.
In factories where greater brightness is necessary for intricate work, you can easily adjust the angle of the exterior lights thanks to its rotatable modular design, which provides you with more illumination where you need it.
Security Flood Lights
One of the most common types of flood light is the security flood light. Security flood lights, as the appellation implies, are primarily employed for security purposes. A motion detector is normally installed in security flood lights to recognize movements in front of the lighting system.
This indicates that when somebody passes through the light, the motion detector recognizes the motion and promptly turns on the light.
Aside from the main purpose of providing an ample amount of lighting, security flood lights are not that distinguishable from conventional flood lights. However, when it comes to installing security flood lights, different methods must be taken.
Although certain flood lights are designed to produce lighting for specific activities such as sports tournaments or music festivals, an increasing number of private homeowners are requesting flood lights to be placed in front of their homes as an added safety measure.
Because environmental design is recognized as a significant factor in preventing crime, lighting can also play a vital part in enhancing your home’s security and preventing possible burglaries.
Motion Sensor Flood Lights
Flood lights with motion sensors illuminate every time they sense a human or animal movement. In fact, a motion sensor flood light is under the category of security flood light.
This type of security flood light comes in handy in two instances. For starters, it will keep undesirable trespassers off your land. People and animals are both included.
Many individuals consider installing these types of motion sensor lights in their backyards to deter wild animals from looking for food at night. This type of flood light can keep your pets out of danger if they were to run into a wild animal within your backyard.
Furthermore, a security motion sensor flood light effectively responds to intruders on your premises. When entering a property, thieves use darkness as a covering. A motion-activated flood light instantly breaches the covering by spotlighting the intruder so that everybody can see him. There is a significant chance that the thief will be scared and escape your property.
Motion sensor flood lights are also used for a variety of applications, including home security. During the nighttime, these flood lights are frequently used to brighten entryways.
When you get near the house, the motion detector senses it and lights the area, allowing you to securely walk to your home or upstairs, find the keyhole, and open the door. By adding proper motion sensors, you can augment safety while also ensuring that the flood lights do not dramatically accelerate your monthly electricity consumption.
Individuals primarily use motion sensors, which cause lights to turn on when a motion is detected. There are many different motion sensors available, and you must choose one that meets both your practical and decorative goals when it comes to security motion sensor flood lights.
The following are the most common types of motion sensors:
• Passive Motion Sensor: This sensor merely detects body heat.
• Active Motion Sensor: This type of sensor efficiently detects any type of human or animal movement.
• Dual Motion Sensor: This sensor is regarded as the greatest solution for avoiding systematic errors. Dual motion sensors turn on the lights only when movement and body heat are sensed.
Flood Light With Camera
The next application for security flood lights is in conjunction with surveillance camera systems. Flood lights with cameras that use night mode capabilities are more costly than traditional cameras.
Security flood lights with cameras are an excellent way to brighten dark places, allowing cameras to record any unauthorized actions on your property.
Landscape Flood Lights
Landscape flood lights are typically designed to highlight an element or space from the ground. Some forms of flood lights are often installed high above the ground, whereas landscape flood lights are installed flush into or on the ground. Landscape flood lights are equipped with supporting legs or ground-mount legs that can be driven within the ground.
The main objective of landscape flood lights is to make a specific object stand out from the pack in a particular location. Landscape flood lights, for instance, are frequently used to highlight a house’s exterior walls or landscape features in the backyard, such as beautiful trees. These flood lights are also frequently employed in the garden.
Furthermore, fountains are a favorite element to highlight with landscape flood lights. Numerous landscape designers utilize a variety of flood lights, such as landscape and pole lights, to properly emphasize ornaments and make them extra appealing at the night. Landscape flood lights with color-changing light bulbs are also an ideal option.
Colored LED light bulbs are a common choice in these fixtures and may add a unique touch to your backyard, property, or patio. Landscape lights, like other forms of flood lights, are frequently combined with solar panels as a more energy-efficient ornamental lighting system.
All In One Flood Lights
All-in-one flood lights are distinguished from other types of flood lights by their appearance and functionalities. All elements of all-in-one flood lights are merged into a unified fixture.
This implies that the light bulb, motion detector, solar array, and rechargeable batteries are all integrated into a single fixture. Typically, flood lights feature a separate solar panel or motion detector, as well as an independent battery.
There are several reasons why all-in-one flood lights are necessary. To begin with, these flood lights are far more lightweight and compact than other types of flood lights. They take up very little space and can be applied in places where other flood lights might obviously be too enormous.
Moreover, this fixture has a more minimalist appearance, so these flood lights can be employed as a decorative feature in a veranda, deck, yard, ship, and other locations.
Since they include lighting bulbs in front or underneath the fixture, all-in-one flood lights are frequently put on a vertical surface. If a solar panel is installed in a lamp, it is normally positioned atop the fixture.
Solar landscape flood lights could exclusively be installed in open areas where the roof would not block the solar array from sunlight. Unfortunately, the downside of all-in-one flood lights is that, due to their small size, they deliver inferior intensity and create weaker illumination than standard flood lights.
But overall, all-in-one lights are a particularly lovely form of lighting for both indoor and outdoor décor purposes, and they can give brightness in locations where other types of flood lights would be too enormous or just impractical to install.
Another prevalent type of flood light is the work light. Work lights are distinguished from other types of flood lights by their longevity and dependability. These lights are designed with heavy-duty enclosures and brackets to resist harsh working environments. Under the robust casing is just the same standard flood light that could be found in almost every other flood light sub-type.
Work lights have a sturdy metal shell, a gripping handle for portability, a safety shield to cover the front glass and light bulb, as well as a stand. Work flood lights have extra-sealed housing that makes them watertight and weatherproof as well as suitable for usage in more inclement weather conditions.
Moreover, work lights are available with a short stand or an extendable (typically tripod-style) support. The light fixture’s placement can be modified to acquire a greater lighting direction.
For added intensity, several work lights come in sets of two or even more fixtures. Work lights are often constructed with single or dual heads, which complement the majority of lighting needs.
LED or halogen bulbs are often used to illuminate work lights. Work flood lights typically provide 1,000 to 20,000 or more lumens by high-powered flood lights. Aside from that, there are battery-operated work lights that feature a rechargeable battery and can function without any supplemental power supply.
Unfortunately, due to their superb strength and brightness, such forms of lights can drain smaller-sized batteries in a matter of minutes. As a result, the majority of work lights have a cable that must be hooked into an electrical outlet.
Post Flood Lights (Flagpole Flood Lights)
Post or flagpole flood lights have their own mount that may be attached to a pole or post. LED lights are generally designed to highlight flags at nighttime, although they can also be applied for decorating or other types of illumination.
Post lights are classified into two types: those that can be affixed to the pole and those that can be mounted to the summit of the pole. Indeed, flagpole flood lights are a hybrid of a standard spotlight and a flood light.
Spotlights have sharper and slimmer lighting beans and can only illuminate a limited area straight in front of them, but flood lights are designed to brighten a larger area.
Adding another dimension, flagpole lights are typically used in conjunction with a solar panel. Solar panels render these fixtures portable and much easier to set up.
Also, there is no need for you to put a cable up the pole because it charges via solar power. Because flagpoles are typically situated in open areas, strong sun rays can readily contact solar panels and recharge flood light batteries quite quickly.
Post or flagpole flood lights typically have one head. However, there are certain flagpole flood lights with many heads that light the flag or any object better in the dark and provide a more pleasing appearance.
How Do You Size A Flood Light?
Flood lights are typically available in three sizes for the majority of residences: PAR20, PAR30, and PAR38. However, you should not be tricked by the numbers as each of them just corresponds to the diameter.
Some flood lights may be labeled as “BR” or “R” lamps instead of “PAR” light fixtures. This refers to the form of the lamp’s reflector. The BR is much more bulged, whereas the PAR is flatter. While they are normally interchangeable, certain people choose PAR lights for outdoor applications and BR lights for indoor applications.
Several BR flood lights are BR30 and BR40 in size. Here are their explanations. The numbers 30 and 40 correspond to the bulb’s size, which is measured in 1/8 inch increments. A BR30 bulb measures 3.75 inches, whereas a BR40 bulb measures 5 inches.
Difference Between A Flood Light And A Regular Light
A regular bulb was originally used in practically any location, but it is now exclusively employed in compact and contained locations such as homes, desks, and pendant lighting.
A flood lighting fixture, on the other hand, is incredibly powerful and beams over long distances, allowing it to be widely used as outdoor illumination. It is also commonly incorporated in streets and stadium illumination.
In Terms of Lifespan: In terms of lifespan, there is no competition between the two types of illumination. Regular lights are easily outperformed by flood lights.
Thomas Edison’s first 19th-century regular incandescent light survived up to 41 days. Today’s bulbs have not yet improved a great deal, with the best ones only lasting 2,000 hours. Flood lights, nonetheless, can survive up to 24,000 hours, contingent on the energy they use.
In Terms of Construction: The underlying operation – or method by which they emit illumination – also differs between them. Regular light is quite basic, producing light by delivering energy into the bulb, which generates a brightness in a filament. HID or flood lighting works by energizing electrons in gasses within an arc pipe to produce light. The arc pipe is enclosed in a vacuum.
In Terms of Efficiency: HID lighting, commonly known as flood lighting, is one of the most energy-efficient lighting technologies available. When compared to a regular incandescent bulb, it is about 90% more efficient, according to the US Department of Energy.
Even though the light from a flood lighting fixture is much more intense, the Color Rendition Index – or how illumination matches natural daylight – is poor when contrasted to regular incandescent bulbs.
Outdoor Flood Light Bulbs
Here are some of the most popular types of light bulbs used for outdoor flood lights including their different applications.
LED flood light bulbs have garnered popularity in recent years due to the numerous advantages they offer to those who wish to use them both indoors and outdoors. LEDs generate light by allowing electrical current to travel via a semiconductor component.
Furthermore, LED bulbs are regarded as the most efficient type of outdoor light available due to the beneficial effects they provide. They have a greater life expectancy than many other types of bulbs on the market.
A single LED fixture can last up to 100,000 hours before needing to be replaced. Since they outlast other bulbs, they are also much more cost-effective in the long run as they do not need to be changed frequently.
Aside from that, LED flood light fixtures are more economical in terms of energy use. The lumens per watt of a light bulb are used to measure its efficiency. To put it another way, an LED bulb uses less energy to generate the same level of light as conventional bulbs.
The decreased heat output of an LED light indicates its energy efficiency. LED lights do not produce a lot of temperatures when they are turned on, thus no energy is lost. Certain types of light bulbs squander energy since they generate heat far too quickly, causing them to waste a lot of energy as a result.
LED lights would never malfunction quickly since they gradually fade as they get close to the end of their existence. When they provide less light, it is a cautionary sign that they have to be changed immediately, which implies you will not be taken off-guard and be left alone in the darkness.
Although these are the primary benefits, there are numerous additional benefits to utilizing LED lights for flood light fixtures: they are accessible in a range of various colors. Some of them are equipped with light switches that are adjustable and dimmable, they turn on instantaneously, and they are more compact than other kinds of bulbs. They are also sturdier, which indicates they will not shatter that easily.
In low-pressure sodium flood lighting fixtures, sodium vapor is produced. When subjected to an electrical charge, this vapor illuminates. Sodium vapor lights are notably low-maintenance and energy-efficient.
However, in terms of light color, sodium vapor lights generate a yellowish hue. Certain individuals think the hue seems to be very artificial. This system also takes longer to create light after the fixture is turned on. Sodium vapor lights often do not perform well in security installations where the flood lights are activated by an alarm signal or motion sensor.
High-intensity discharge (HID) lights contain an inbuilt ballast. When an electric arc is formed, it glows and emits light that emanates from the bulb.
They have the highest life expectancy and the greatest efficiency rating. They are 75 to 90% more economical than incandescent flood lights, according to research.
A gas-discharge lamp is referred to as a high-intensity discharge. They are the most classic kind of electrical light. Mercurial vapor, low- and high-pressure sodium, and metal halide lights are all common forms of HID lighting.
Moreover, HID lights necessitate ignition, which is usually given by a voltage spike or a third conductor within the bulb. Once lighted, the electrical arc starts to vaporize the metallic salts within the bulb, considerably increasing its luminous output while also increasing lighting quality.
Since the lighting brightness is reliant on and fluctuates as the substance inside the bulb evaporates into plasma, HID lighting necessitates a “warm-up” process. Furthermore, as the lighting heats up, it takes more voltage to work. An electric ballast balances the voltage levels of HID light fixtures.
As the HID light fixture gets old, more voltage would be needed to generate the same level of illumination, until the voltage ultimately reaches the preset resistance given by the ballast. HID fixtures become less productive over time as the light fades, requiring higher voltage to generate the same luminance.
A halogen is yet another type of bulb that is widely used in outdoor flood lights. In actuality, until LEDs arrived, they were widely regarded as the greatest type of bulb for usage in outdoor installations. Such bulbs are frequently considered an improved variant of incandescent bulbs.
Halogens are incredibly affordable, costing up to ten times less than an LED bulb and roughly half the price of a CFL light. A CRI (Color Rendering Index) is a value assigned to light bulbs. When the CRI is significant, it indicates that the light can create very strong light, which halogen bulbs excel at.
The size of the lightbulb itself is one other factor why halogen lights are so prevalent with outdoor flood lights. Apart from being extremely compact, halogen bulbs are also quite intense.
In contrast to CFL lights, which require minutes to achieve their maximum brightness capability, halogen bulbs illuminate very quickly. Other advantages of halogen bulbs entail the feature that they are dimmable, work well with motion-driven lighting, and are better for the planet than CFL bulbs since they do not hold mercury.
The incandescent lightbulb is an electrical source of light that operates upon incandescence, which is the generation of light created by getting the filament heated.
They are available in a vast array of voltages, sizes, and wattages. Incandescent bulbs were the main thing before LEDs became popular.
An incandescent bulb is generally made out of a glass casing that houses a tungsten filament. An electrical charge flows through the filament, converting it to a heated temperature that is high enough to create light.
Furthermore, incandescent light bulbs typically have a stem or glass mounting affixed to the bulb’s bottom, allowing the electrical connections to travel through the enclosure without leaking gas or air.
The filament and its lead cables are supported by small conductors inserted in the stem. To retain and safeguard the filament from evaporation, the encompassing glass casing includes either an inert gas or a vacuum.
Incandescent light bulbs do not necessitate any additional regulating devices, have a relatively inexpensive manufacturing rate, and may operate on both alternating or direct current.
Moreover, you can safely use them inside or outside your house and are interoperable with controlling units including dimmers, motion sensors, and more.
Fluorescent lighting is a multipurpose kind of lighting that you are sure to cross paths inside your workplace, school, or supermarket. It is well-known for its energy efficiency when contrasted to incandescent and halogen lightbulbs, as well as its lower cost when compared to LEDs.
To generate light, fluorescent bulbs rely on a chemical process within a glass cylinder. This chemical reaction entails the interaction of gasses and mercury vapor, which results in the production of an undetectable UV light. The unseen UV radiation activates the phosphor material coating inside of the glass cylinder, resulting in the emission of bright white fluorescent illumination.
High-pressure sodium (HPS) fixtures are a type of high-intensity lightbulb that produces a huge light output, which is typically required for street and security illumination.
The fusion of metals and gasses within the glass cylinder generates an orange-white glow, which is similar to that found in street light sources.
When first opened, HPS bulbs emit a deep pink glow, and when heated, they emit strong pinkish-orange light. Furthermore, because of the broad color temperature range generated and the comparatively low cost of operating the lights, HPS fixtures are preferred by indoor gardeners for mass cultivation.
When tested for photopic illumination conditions, high-pressure sodium lights have an efficiency of roughly 100 lumens per watt. The more powerful 600att models have an efficiency of up to 150 lumens per watt.
A metal-halide (MH) fixture is electrical lighting that generates light using an electrical arc created by a gaseous combination of metal halides and vaporized mercury.
This form of light is also referred to as an ‘MH’ light. This is an HID (High-Intensity Discharge) type of light bulb, which indicates it gets most of its illumination from an electric arc inside a compact vacuum tube.
It is getting more widespread as a result of its high-quality white light and efficiency. The MH light is most commonly found in stadiums and sporting fields. It is also commonly utilized in metropolitan areas, parking lots, and street illumination.
CFL Light bulbs
CFL light bulbs provide various advantages but are not close enough to be regarded as a credible alternative for flood light interoperability. The excellent thing is that these bulbs are less costly than others, and they have a longer life expectancy than halogens.
However, it is noteworthy to mention that they are brittle, which is not something you want in a device built for outdoor applications. The reality that switching the lights on and off reduces their longevity is also a huge disadvantage, particularly if you have motion-activated flood lights.
Lastly, the fact that CFL bulbs include mercury, which is highly dangerous, makes them a not-so-good outdoor flood lighting option.
Indoor Flood Light Bulbs
LED Flood light Bulb: LED bulbs are the most adept at generating illumination and the most energy-efficient of all indoor flood lighting options. They survive up to 5 times greater than most bulbs and have dropped in cost so dramatically that there is no excuse not to use them if you want a long-term, ecological, and non-toxic choice.
Compact Fluorescent Bulb: Compact fluorescent flood lighting bulbs are less costly to acquire in the beginning. They have a limited life expectancy and carry mercury, which, if damaged, might be expelled as vapor. If you are going to use compact fluorescent indoors, go for a full spectrum.
Halogen Bulb: Halogen bulbs produce more light than regular incandescent bulbs. They can make a significant contribution to overall indoor lighting needs when paired with other light sources.
However, halogens get rather hot when ignited, thus it is advisable not to leave them on for long periods indoors; they must be turned off regularly.
How Many Lumens For Flood Light?
Flood lights usually necessitate around 700 to 1300 lumens. The more lumens the lights produce, the more intense they are and the more protected your space will be.
Approximately 300 to 700 lumens are required for motion-activated flood lights. However, because these types of lighting fixtures have different brightness levels, the brightness may differ.
Which Flood Light Bulb Is The Best?
LED flood light bulbs are widely regarded as the best option because they are the most energy-efficient alternative. LEDs use less energy than incandescent lights while producing the same amount of light.
This enables them to generate the same amount of brightness while consuming less energy. LEDs have a lifespan of more than 20 years and do not contain mercury. Plus, they are very durable, not like the other bulbs that can easily shatter.
Can You Put a Regular Bulb In A Flood Light?
In general, yes. The preponderance of light outlets is still Edison-based, therefore, if the flood light outlet is the same as a regular light bulb, it would be fine. Sockets have a maximum wattage that is indicated or imprinted on the unit.
Plastic-made sockets are typically rated at a maximum of 60 watts. The greater wattage sockets are usually made of porcelain. It all boils down to the capability to withstand the heat created by the bulb.
Where To Use Flood Lights
Here are the locations where you can maximize the purpose of flood lights:
• Stage concerts (music festivals, live performances, and the like)
• Sports events (soccer fields, racing tracks, baseball arenas, and the like)
• Yard (can be your front or backyard)
• Parking areas (garage)
• Stairways and pathways
• Home or office entrances
• Any area inside the house with blind spots
A good alternative to using flood lights indoors, is to choose low or high bay light fixtures depending on your ceiling height. A low or high bay light fixture has reflectors that can help reduce glare and spread light for efficiently for an indoor setting.
How To Position Flood Lights On House
You can consider installing your flood lights near your roof level, where they will beam on the best portion of the property and will be less inclined to be interfered with.
Opt for 2 or 3 lighting systems that can be mounted in an upper corner to brighten a larger area. You can even install motion-sensing flood lights above your entrance doors. In this way, you can deter intruders.
Nevertheless, the main purpose of landscape or decorative flood lighting is proportion and arrangement. You can incorporate lighting splashes across the entrance of your home so that the light gradually pulls your eye across the full front of the house.
Layering is vital, rather than simply filling certain types of dormers and roofs with light. You can also flood light the architectural elements that you wish to draw attention to.
How Do I Choose A Flood Light?
Here are the factors that you have to consider when choosing a flood light:
• High Lumens: A lumen is a unit of measurement for the brightness of a light; the greater the lumen, the stronger the illumination. When selecting a flood light, keep in mind that the larger the space, the more lumens you will need.
• The Angle of the Beam: Check the angle at which lighting is dispersed. The larger the angle, the more area is illuminated.
• Color Temperature: This is calculated using Kelvin (K) units and ranges from “warm” to “cool” lighting. The greater the Kelvin value, the cooler the light.
If you are looking for flood lights to brighten garden elements, a warmer, more pleasant color temperature featuring a minimal Kelvin value, like warm white, would be a good choice.
A cooler white with a higher Kelvin value produces a brighter light, which is suitable for functional or security reasons.
Do Halogen Flood Lights Get Hot?
Yes. Halogen lights may reach immensely hot temperatures when left on for an extended duration, which implies you should not touch them with your bare hands.
Do Flood Lights Deter Burglars?
Yes, flood lights can truly deter burglars. These criminals choose properties with little to no visible security. Break-ins occur at nighttime, when thieves can spend more time sneaking into the home under the cover of darkness.
Hence, flood lights would act as an effective deterrent to stop those burglars from stealing your belongings and damaging your property.
How Long Do Flood Lights Last?
An LED flood light can survive up to 50,000 hours, which is a significant upgrade over halogen lighting. Since LED flood lights survive longer, they necessitate less replacement, making them a more cost-effective solution.
However, if you use other flood light bulbs, such as halogen or incandescent, they will only last around 2,000 to 3,000 hours. Thus, it is highly recommended to go for LED flood lights.
