Commercial LED flood lights for building facades, signs, entrances, loading areas and security zones. Our knuckle mount flood lights range from 15W to 100W, including power and color selectable models with a built-in on/off photocell for dusk-to-dawn operation. Every fixture runs on 120-277V, has an IP65-rated bronze housing and is backed by a 5-year warranty.
Flood Lights vs Area Lights
Flood lights are aimed. They put light on a specific surface or zone, such as a wall, sign, doorway or fence line. Area lights are mounted high on light poles to spread light evenly across open spaces like parking lots. If you need uniform coverage across a full lot, choose area lights; if you need light concentrated on a target, choose a flood light.
Common Uses for Outdoor LED Flood Lights
- Facade and building wash: Aim from the ground or below the roofline to make your building visible and identifiable after dark.
- Sign lighting: Light monument and wall signs without internal illumination. Match wattage to sign size and mounting distance.
- Entrances and loading areas: Put light on doorways, dock aprons and service yards so staff can work safely and read labels.
- Security and perimeter lighting: Cover fence lines, yards and entrances so security cameras capture clear footage.
- Parking lot edges: Fill corners and building edges where poles are not practical. Use area lights for the main lot.
How to Choose the Right Flood Light
- Wattage and lumens: Start with the size of the target and how far the fixture is from it. 15W to 30W models suit doorways, small signs and landscape features; 30W to 50W models cover entrances, walls and mid-size signs; 60W to 100W models light larger facades, yards and loading areas.
- Selectable vs fixed output: Power and color selectable flood lights let you set wattage and color temperature on site, so one SKU covers multiple applications. Fixed 15W and 100W 5000K models are simple, cost-effective choices when the output is already known.
- Aiming and mounting: Knuckle mounts thread into a standard junction box or conduit and pivot to aim light exactly where it is needed. For pole installs, see our brackets and adapters.
- Controls: For security, facade and sign lighting, choose a model with a built-in photocell so lights turn on at dusk and off at dawn automatically. The on/off switch lets you disable the photocell when the fixture is controlled by a timer or switch.
- Weather rating: IP65 housings are sealed against dust and protected from water jets, suitable for full outdoor exposure.

LED Flood Lights Questions
How many flood lights do I need, and how far apart?
It depends on the target’s size, the distance, and how bright you want it, so there’s no single answer. A practical method is to use one fixture per door or per section of wall, overlap the beams so there are no dark gaps, and use two smaller lights instead of one large one when a wall is wide. Before you drill, temporarily aim one fixture at the target after dark and see how it looks. If you send us the dimensions and mounting distance, we’ll recommend a wattage and quantity.
Should I match the wattage of my old halogen or metal halide flood light?
No. LEDs produce far more light per watt, so an LED flood light at a fraction of the wattage can equal or beat the old fixture. Compare brightness (lumens), not watts. Swapping watt for watt gives you more light than you need and gives up the energy savings. If you’re using a power-selectable model, start at the lowest setting, check it at night, and step up only if needed.
Why does my photocell flood light keep turning on and off all night?
This is the most common photocell problem. The photocell reads surrounding light, so if the fixture’s own beam, a reflection, or a nearby light shines on the sensor, it thinks it’s daytime and shuts off. Then it sees darkness and turns back on. To fix it, re-aim the fixture so its beam doesn’t reflect onto the sensor, shield the sensor from other lights, or use the on/off switch to disable the photocell and run the light from a timer or wall switch.
Can I mount a knuckle mount flood light without a junction box, or on a pole?
The knuckle mount threads into a standard junction box or conduit. On a surface with no box, install a weatherproof box first. For poles, use a bracket or adapter. Also, the IP65 rating covers the fixture, not an unsealed connection. Make sure the junction box is gasketed and the opening is sealed so water can’t get in at the mount.
Will it work on my building’s voltage? Do I need a transformer?
Our flood lights accept 120-277V, so they work on 120V, 208V, 240V, and 277V circuits without a transformer. They aren’t rated for 480V service. Check your panel or the fixture you’re replacing before ordering. If your site runs 480V, call us and we’ll point you to the right option.
Should I use a flood light or a wall pack?
Use a wall pack when you want a permanent, low-profile fixture that lights the area directly below it, like a door or walkway. Use a flood light when you need to aim light at something away from the fixture, such as a sign or a section of facade, or when you want to adjust the direction later.
