LED floodlights can also be called Outdoor LED spotlights, or LED projectors, which are large-area lighting fixtures used outdoors.

It has made technical improvements and innovations on the basis of traditional metal halide floodlights and HPS floodlight fixtures.

Use LED solid cold light source to replace traditional metal halide bulb and HPS bulb light source. LED flood light does not contain any toxic gas, will not pollute the environment, and it can be recycled.

Some of the most common applications of LED floodlights include the following:

  1. Stadium fields, such as football field, basketball court, tennis court and other sports spaces.
  2. Public places: parks, plaza, gardens, roadway lighting, high mast lighting.
  3. Landscape lighting for trees,
  4. Industrial lighting for Warehouse, workshop, and factory.
  5. Commercial lighting for train stations, subway, parking lots, etc.

Horizontal light. Beam angle generally is 120-180° which will improve the efficiency of light utilization, reducing lighting pollution and waste.

High lumens. most of them are about 100lm/W output. Even it can be up to 150lm/W output for best outdoor flood lights in markets, saving much more 80% energy than traditional halogen flood lights or HPS floodlights.

Longer lifespan. The service life of LED reflector light is at least twice as long as that of a traditional projection lamp, which can reach 50000hrs. The outdoor led projection light produced in 2013 is still in normal operation, and its service life has exceeded 7 years.

Instantaneous start-up. No need for a pre-warm-up start-up.

Low Light decay. It is 1% decrease at 3000 hours. 3% decrease in 10000 hours.

Environment-friendly. Led floodlights do not contain mercury, toxic gases, and liquids, and will not pollute the environment. At the same time, some lamps can be replaced and reused by outdoor LED flood light bulbs.

As the latest generation of lighting fixtures, LED floodlights have the characteristics of environmental protection, energy saving and high luminous efficiency.

More and more people choose it to replace traditional metal halide flood light or HPS flood light. So, what is a LED floodlight equivalent to metal halide/HPS flood lights? You can refer to the chart:

As far, the common & standard wattage for led flood light fixtures include 10W 20W 30W 50W 70W 100W 150W 200W 250W 300W 400W 500W 1000W 2000W. We are making a list for different places for your reference:

Application placeWattageInstallation heightLumens (lm)
Parking lots100W-150W6m-8m10000-18000lm
Football field500Watt-1000Watt10m-20m60000-130000lm
Tennis court150Watt-250Watt8m-10m18000-30000lm
High mast at public plaza400W-2000Watt15m-50m50000-230000lm

In general, when people say flood lights or spotlights, they mean the same thing. But technically, there are some differences in beam angle.

Generally, flood lights have bigger beam angle like 90/120° which is an application for Lighting up the whole scene, suitable for big area lighting.

However, the spotlight fixture is with a narrow beam angle like 25/45/60°, These lights look like a beam of light, and generally, the straight-line distance illuminates will be farther than floodlights. Suitable for local lighting to highlight the characteristics of objects.

Outdoor floodlights, also known as outdoor spotlights, almost all large-area lighting fixtures used outdoors can be regarded as floodlights. It is often used in stadiums, building outlines, squares, overpasses, tunnels, parks and backyards, gardens, etc. As these lamps have a large number of options in the market with different specifications, it may be challenging to choose suitable floodlights for different application. You need to consider the following factors when you choose which outdoor LED floodlight is working for you.

Input voltage

The input voltage of LED floodlights on the market mainly includes 110-120VAC for japan, USA, Canada markets, 220-240VAC for other countries, and low voltage AC/DC12V, 24V, 36V, 48V, 60V. Before purchasing floodlights fixtures , Please confirm which input voltage meets your needs.


When choosing exterior led floodlights, lumen value is more important than power value. Power value (Wattage) measures the energy required to illuminate the product, and lumens determines the brightness of the lamp. This means that the more lumens of the product, the brighter the lamp. Consumers should not choose projection lamps based on the power value (watts), but should consider how much brightness (lumens) they provide us.


Wattage is a measure of the energy consumption of a lamp, not the amount of light it emits. For led floodlights, generally 10W to 1000Watt optional. For small places, it is enough for 10W-50Watt, they are suitable for installation at a height of 3-5 meters. Then the higher wattage is better choices for higher place.

Beam angle

The beam angle of the led flood lights are wide or narrow, and the range is between 3°~140°. Different application places have different requirements for the luminous angle. For some trees, landscapes or building outlines, it is more suitable to choose a narrow beam angle led floodlights, which can play a key part of the lighting effect, highlighting the characteristics of the illuminated object. However, for large spaces, then the wide distribution floodlights will be much better, such as 120° or 70*140°.

Color temperature

Color temperature refers to the color value emitted by the light source. Different light colors of lamps give people different feelings. There are three options for LED lamps on the market.

  • 3000K warm white: looks like yellow, making people feel warm, comfortable.
  • 4000K-4500K Natural white: looks like sunlight.
  • 5500k-6500k cold white: Bluish white light.

For outdoor lighting, it depends on what you want to illuminate with floodlights. Smaller places such as tree, terraces, backyard and pathway will require fewer lumens, while larger sites such as stadiums, squares and roads will require more lumens. A reference table can be listed here:

Residential Garden1000-3000lm
Stadium fields30000-100000lm

Yes. It is a smart choice.

LED is latest technology in lighting, it can be saving much more 60% at least then traditional metal halide flood lamps, for example, 20W LED Flood light is ok to replace 150Watt old floodlights. All of old flood lights fixtures are with E27 OR R7S bulb, there are same e27 and R7S LED Bulb to replace them, it is easy to do replacements. Just check if the input voltage of led flood light bulb is same as existing metal halide bulb, because there are 220-240VAC Input and 110-120VAC input types optional around the world.

Dimmable LED flood lights can be dimmed, but common LED floodlights are not. You need to check if your floodlights are dimmable or not.

There are different light sources for flood lamps. Metal halide flood light fixtures, HPS floodlights fixture and LED Flood lamps. They are different in lifespan as following:

  • Metal halide type: 8000-10000 Hours
  • HPS Flood lights: 20000 Hours
  • LED Flood lights: >50000 Hours.

LED floodlights is the longest lifespan, and best way to save cost.

The flicker/flashing of led lights is mainly related to LED chips or LED driver (power supply), and LED floodlights is no exception.

First, the quality of LED chips. Normal single 1W led chips withstand current: 280-300mA, voltage: 3.0-3.4V. If you use low-quality LED chips, it will not match the standard LED drive power parameters. Once the Led chips are subjected to excessive current, it will flash on and off. In severe cases, the gold wire or copper wire built in the chips will be burned, causing the chips to not light up.

Second, the Led driver problem. The main reason is that the electrolytic capacity inside the power supply is insufficient, and the output current and voltage of the lighting system cannot be controlled stably, which makes the LED flood light flashes that turn on and off.

Third, the temperature of the LED flood light is too high. Generally, this kind of light appears in the LED flood light fixtures with built-in power supply. If the driver has an over-temperature protection function, and the material heat dissipation performance of the lamp cannot meet the requirements, the driver over-temperature protection will start to work and there will be flicker, for example, 20W floodlight housing is used to assemble 30W lamp, in this case, the heat dissipation will be too bad to working well.

Fourth, the floodlight is flooded. Floodlights are often used outdoors, if the waterproof strength is not enough, water ingress is likely to occur. Once water enters, it may cause the LED lamp beads to rust and break. As a result, flickering occurs.

  1. The connection method is wrong or the connection connector is not connected to cause no power;
  2. The problem of the lamp equipment, such as the driving power supply is broken, the led chip is burned out, or the quality of the chemical products in the lamp, etc., if it is a connection problem, we can deal with it easily. Connect the digital camera, if it is the second problem, you need a professional or return to the factory for repair or malfunction.

There are many different types as following:

COB led flood lighting: This kind of floodlight uses the previous generation of LED light source technology-COB. Different numbers of LED chips are integrated on a small substrate, which can be assembled and produced quickly. At the same time, COB chips can also be very convenient to customize the color temperature of 2000K-2500K, and the CRI can easily achieve more than 90.

SMD: SMD LED Flood lights fixtures mainly use SMD3030, SMD5730 or SMD2835 chips as light sources. It is better in heat performance and higher in brightness than COB types. It is main trend in markets.

Modular led flood lights: This kind of scheme adopts modular design. The power of each module is planned to be 50W 100W or 200W, and then each module is spliced. This not only improves the heat dissipation performance of the lamp, but also makes maintenance easier. At the same time, the illumination angle of some modules can be adjusted, and each module can be illuminated in different directions. It is mostly used in outdoor stadiums such as football fields, basketball courts, tennis courts, tunnels, high pole lights, construction sites, etc.

Low voltage LED flood lights: The input voltage of this kind of floodlight is generally AC/DC12V 24V 36V 48V 60V. Compared with the high-voltage 110Volt or 220VAC input floodlight, the low voltage type will be safer, especially when it is installed outdoors, and easy to be touched by human being. Mostly used in special places such as ships, mines, petrochemicals, petrol stations, etc.

DOB Led flood lights: “DOB” is the abbreviation of “Driver on board”, which means that the power supply is on the board. The so-called DOB led floodlights means that the AC power supply and led chips are integrated on the PCB at the same time. It is also called driverless AC LED flood lights. The cost of this luminaries is the lowest, but in terms of quality, it is not as good as floodlights with constant current drive. Moreover, the input voltage of most DOB Flood lights can only be 220-240VAC, and the power factor is generally only about 0.5-0.6. Africa, Middle East, Southeast Asia, South Asia, South America non-developed markets. This kind of lamps is not suitable for commercial and industrial projects and places with strict quality requirements.

Explosion proof flood LED light: It refers to a floodlight used in dangerous places where combustible gas and dust exist, and can prevent arcs, sparks and high temperature that may be generated inside the lamp from igniting combustible gases and dust in the surrounding environment, so as to meet the requirements of explosion-proof. It belongs to a special kind of lamp, and its protection level is higher than that of conventional floodlights. Suitable for various indoor and outdoor operations and construction sites such as flammable and explosive places, oil fields, offshore oil platforms, ships, metallurgy, petrochemicals, etc.

Exterior landscape flood lights: This type of floodlight is mainly used for lighting effects of outdoor landscapes, such as illuminating trees and rockery at night. Their power is mostly less than 50W, and their light-emitting angle is mostly 30°. Mostly used in parks, squares and other places.

Smart flood lights: It is including motion sensor, photocell, time control floodlight fixtures, most of them can be turned on/off automatically through some special setup.

RGB led flood light: This is color changing or special color such as green, blue, red, yellow types for special application.

Solar powered led flood lights: It is the most energy-saving type of floodlight, and it powers the floodlight by converting solar energy into electrical energy. Very suitable for use in countries or regions with sufficient sunlight, such as Africa, the Philippines, Indonesia, Brazil and other places.

Some LED floodlights are dimmable, but not all. You have to check the products specification if it is dimmable or not. Please don’t work led floodlights with any dimmer if the led flood lights are not dimmable, or maybe it will be burned out. By the way, there are mainly 3 types dimmable options-PWM dimmable, 0/1-10V dimmable, or DALI dimmable. You have to choose these dimmable flood lights fixture if you would like to dimming.

Outdoor security floodlights generally add some functions to ordinary LED floodlights, such as photocell, PIR Sensor device, solar, which can make the lights turn on or off intelligently. Or with camera to realize monitoring function. This kind of lights are mostly used in residential areas or backyards, and the power is between 10W-50Watt.

If you want your flood lights to be automatically turned off during the day and turned on at night, then dusk to dawn flood lights is the best good solutions for you.

The dusk to dawn flood lights also called photocell flood lights, means there is a photocell device on the floodlights, When the light intensity of the surrounding environment decreases to a certain level (at night or sunset), the light controller will automatically turn on the LED flood light, otherwise, it will automatically turn off the flood lamp fixture.

Motion flood lights is a smart light fixture. It is added extra sensor device on the floodlights. It uses the sensor to detect the movement of objects within a certain range and decides whether to turn on or turn off the flood lights. Generally, there are PIR Sensor and Microwave radar sensor optional. PIR Sensor floodlights mainly rely on sensing the movement of objects with a certain temperature to turn on or turn off the lights, such as people, animals, etc. However, the Microwave radar flood lights can sense the movement of any object. And it is more sensitive and better solution than PIR Sensor type. But the cost is also higher.

The motion detector is a small device that can detect infrared waves, that is, heat waves radiated from moving objects. When the detector detects an object moving in its field of view—especially warmer objects such as people, animals, and cars—it turns on the flood lights automatically. It will turn off smartly when the PIR Sensor will not detect any movement. In this case, it can save energy to the maximum.


There is a switch on motion sensor, you can adjust the switch off when you don’t like the motion sensor function.

What keeps my light on all the time? There are several things that can cause your motion detector to stay working, including aging, storm damage, power surges, improper installation and improper settings. Some problems can be easily solved without professional help.

The main difference between floodlights and street lamps is that street lamps generally illuminate the road surface directionally, and the width of the irradiation has certain requirements. Usually, street lighting uses polarized lenses to achieve this requirement. The pursuit of floodlights is to illuminate a wider range as much as possible, and at the same time, the illumination range of floodlights is non-directional and can be changed at will with the mounting bracket.

There are 3 installation for flood lights( Wall mounted, Surface installation, Base installation)

The steps as following:

  1. There are mounting holes on the projector lamp bracket.
  2. Lift the base to the installation position.
  3. Use a pen or other tools to make the position of the screw hole on the wall. Or put it on to high pole.
  4. Drill holes.
  5. Install the base, fix the screws, etc.
  6. Adjust the screws on the fixing clip to adjust the floodlight to a proper angle of illumination.
  7. There are three power cords at the bottom of the flood light fixture. This cord is a 3-core wire; the blue wire is the neutral wire N, the brown-red wires is the live wire L, and the yellow/yellow-green wire is the ground wire PE.

This is installation drawing for reference:

You also can check this videos for installation steps:

By the way, there are several things you need to know before doing installation of flood lights:

  1. The floodlight is designed to be waterproof and moisture-proof, and its protection level can reach IP65. It can withstand the test of rain from top to bottom, but cannot work under water, and its protection level does not meet the requirements of underwater work.
  2. The location where the floodlight is installed must have sufficient bearing capacity, and its bearing capacity should be able to bear more than 10 times the weight of the driver.
  3. The working power supply of the floodlight is high-voltage alternating current, which should be kept away from places easily accessible by people, and the floodlight must be grounded, and the grounding wire must be grounded.
  4. The floodlight is a power-type device and is very sensitive to the ambient temperature. When the working environment temperature is higher than 45°C, its life will be significantly reduced, and there will be signs of serious light decay. Therefore, the floodlight should be placed in a ventilated place to keep the floodlight with relatively good heat dissipation environmental conditions.
  5. The working environment temperature of the flood light should be between -25°C~+45°C. The temperature of the workplace must not exceed 45°C to ensure the service life of the floodlight.
  6. Since the power of the floodlight is relatively large, the appropriate power cord should be selected according to the actual power when laying the power cord. And separate phase power supply.
