Specifying a Flood Light for the Target You Are Lighting
A flood light is defined by what it points at. Unlike a fixture that lights a room evenly, a flood is aimed at a surface or an area from a distance, so output, beam spread, and mounting all get chosen against that target rather than against a square footage.
Flood, Wall Pack, or Area Light
These three cover exterior lighting between them and they are not substitutes. A flood aims an adjustable beam at something specific: a building face, a sign, a loading area, a field. A wall pack mounts flat against a wall and washes the ground directly below and around it, which is perimeter and doorway lighting rather than targeted lighting. An area light sits on a pole and throws a controlled distribution downward across open ground, which is what parking lots use.
Choosing wrong shows up immediately on site. A flood aimed at a parking lot from a pole creates hot spots and glare where an area light would have laid down even coverage, and Lumera's area lights collection covers that pole-mounted distribution.
For building perimeters and entries where the fixture should sit flush on the wall instead of being aimed, wall packs are the correct fixture type.
Size by Lumens, Not by Watts
Wattage tells you what a fixture draws, not what it delivers, and LED efficiency varies enough between products that two fixtures at the same wattage can differ noticeably in output. Lumens are the number that matters. Wattage is still useful as a rough replacement guide when swapping out older metal halide or high-pressure sodium heads, since LED does the same job at a fraction of the draw, but confirm the actual lumen figure on the listing before committing. Mounting height factors in too, because light falls off with distance, so a fixture that lights a sign well at 10 feet may be underpowered on the same sign at 25 feet.
Beam Spread and Aiming
Beam angle decides whether light lands where you want it or spills past the target. A narrow beam concentrates output and throws farther, which suits tall facades, flagpoles, and anything being lit from a distance. A wide beam covers more area at shorter range, which is the right answer for a broad wall, a yard, or a loading dock. Bullet-style floods tend toward the narrow end and larger stadium-style fixtures toward wide area coverage, but check the listed beam angle rather than assuming from the housing shape. Aiming matters just as much as the fixture: light that misses the target becomes glare for a neighbor and wasted energy for the owner.
Mounting Options
Mounting determines both where a flood can go and how precisely it can be aimed.
- Knuckle or slip-fitter: threads onto a stud and rotates, the most common adjustable mount for wall and eave locations
- Trunnion or yoke bracket: bolts to a wall, ground, or pole and tilts through a wide arc, the standard for larger fixtures
- U-bracket: surface mounts flat and gives limited adjustment, useful in tight clearances
- Ground stake: sets a smaller landscape-style flood directly into soil for uplighting
Larger fixtures on tall poles carry real wind load, so the mount and pole have to be rated for the fixture, not just able to physically hold it.
Selectable Wattage and Color Temperature
Many current flood lights ship with field-selectable wattage, color temperature, or both, set with a small switch on the fixture before installation. This is genuinely useful for a distributor and an installer, because one part number covers several specifications and you can decide the final setting on site once you see the result. It also cuts what has to be stocked for a multi-building job. Check the listing for which options a given model offers, since the available steps vary by product line.
Photocell and Dusk-to-Dawn Control
A photocell switches the fixture on at dark and off at daylight without any timer to program or reset seasonally. Flood lights are sold three ways: with the photocell installed, photocell-ready with a socket for one to be added, or without any provision at all. Confirm which before ordering, because a photocell-ready fixture still needs the sensor bought separately. Lumera's photocells collection covers those sensors on their own.
Where motion detection rather than dusk-to-dawn operation is what the site needs, the security lights collection covers fixtures built around that trigger.
Voltage and Circuit Requirements
Most commercial floods accept a universal input range covering 120V through 277V, which lets the same fixture work on residential and commercial service. Larger installations sometimes run on 480V, and those are separate part numbers rather than a setting on the same fixture, so match the voltage to the building's actual service before ordering. Flood lights connect to building wiring and often sit at height, so a licensed electrician should handle the circuit, the mounting, and the aiming. Confirm the fixture is wet-location rated for any fully exposed position.
Fixtures or Lamps
One distinction worth clearing up before ordering: this collection holds complete fixtures with their own driver and mounting bracket. A flood light bulb is a different product, a screw-in lamp that goes into an existing socket, and Lumera lists those under PAR lamps.
Flood Light Questions, Answered
What wattage LED flood light do I need?
Compare lumens rather than watts, since LED efficiency varies between products and wattage only tells you the draw. Wattage works as a rough guide when replacing older metal halide or high-pressure sodium heads, but check the listed lumen output and factor in mounting height, because light falls off with distance from the target.
What is the difference between a flood light, a wall pack, and an area light?
A flood aims an adjustable beam at a specific target such as a sign or building face. A wall pack mounts flat on a wall and washes the ground below it. An area light sits on a pole and spreads a controlled distribution downward across open ground, which is what parking lots use.
How do LED flood lights mount?
The common options are a knuckle or slip-fitter that threads onto a stud and rotates, a trunnion or yoke bracket that bolts to a surface and tilts, a U-bracket for flat surface mounting in tight clearances, and a ground stake for smaller landscape-style floods. Larger fixtures carry wind load, so the mount and pole both need to be rated for the fixture.
Do these flood lights include a photocell?
It depends on the model. Fixtures are sold with a photocell installed, photocell-ready with a socket for one to be added later, or with no provision at all. Check the specific listing, since a photocell-ready fixture requires buying the sensor separately.
What does selectable wattage and CCT mean?
Many current floods have a small switch on the fixture that sets wattage, color temperature, or both before installation. One part number then covers several specifications, and the final setting gets chosen on site. The available steps vary by product line, so check what a given model offers.
Can these flood lights run on 480V?
Some models are built for 480V service, but they are separate part numbers rather than a switch setting on a standard fixture. Most commercial floods accept a universal 120V through 277V input. Confirm your building's actual supply voltage before ordering.
