Illuminate parking lots and roads with the warm, yellow light of these high-pressure sodium bulbs. Brightness is measured in lumens; the higher the lumens, the brighter the bulb. Color rendering index (CRI) is a measurement on a scale of 0-100 of how accurately the light from a bulb represents an object's true colors; the higher the number, the more natural the colors appear. Any CRI value over 80 will show colors true to life. A bulb’s estimated yearly cost is based on 3 hours of usage per day at $0.11 per kWh. Bulbs cannot be sold to Canada because they exceed local regulatory limits on mercury.

Non-cycling bulbs prevent damage to ballasts and starters because they remain off at the end of their service life instead of cycling on and off like other high pressure sodium bulbs.

An instant restart means you won’t have to wait the several minutes it takes other high-pressure sodium bulbs to restart.

Replace high-intensity discharge (HID) lights with the longer-lasting, energy-efficient LEDs. Brightness is measured in lumens; the higher the lumens, the brighter the bulb. LED lights are perceived as brighter at night than high-intensity discharge light technologies, so they require fewer lumens to provide the same brightness. Match your old light’s wattage to find the right LED bulb. A bulb’s estimated yearly cost is based on 3 hours of usage per day at $0.11 per kWh.

Plug socket-ready bulbs into an existing fixture with a compatible ballast.

Ballast bypass bulbs eliminate the need for a ballast, so the socket must be wired directly to the power source.

Switch from the yellow light of high-pressure sodium to the white light of metal halide without changing ballasts. Brightness is measured in lumens; the higher the lumens, the brighter the bulb. Color rendering index (CRI) is a measurement on a scale of 0-100 of how accurately the light from a bulb represents an object's true colors; the higher the number, the more natural the colors appear. Any CRI value over 80 will show colors true to life. A bulb’s estimated yearly cost is based on 3 hours of usage per day at $0.11 per kWh.

Bulbs with an EX39 base number will not burst when they fail.

Use these lights in large, open areas such as warehouses and manufacturing spaces where the ceiling is up to 30-ft. high. They are ETL and C-ETL listed for Class I Division 2 Groups A, B, C, and D, Class II Divisions 1 and 2, Groups E, F, and G, and Class III Divisions 1 and 2 for use in environments where ignitable concentrations of acetylene, hydrogen, ethylene, and propane occur infrequently, such as in the case of an accidental spill or failure of a ventilation system. With built-in LEDs, these lights last longer, are more efficient, and generate less heat than other light technologies. They produce a neutral light appearance, which creates a balanced environment for general work areas. These lights produce a wide beam of uniform light. Lights can be hardwired to operate on any of the voltages listed. Thread onto 3/4 NPT conduit to suspend lights from the ceiling.

With a lower profile design than other bay lights, linear bay lights mount closer to ceilings, providing more room for racks or shelving. Use them in large, open areas such as warehouses and manufacturing spaces where the ceiling is up to 40 ft. high. Rated for use in damp locations, these lights withstand humidity and moisture. They can be hardwired to operate on any of the voltages listed.

Style A and C lights require suspension hardware (sold separately), which includes two wire rope slings with hooks and two wire rope clamps. No tools required—adjust the length of the suspension hardware and tighten the clamps to secure. Style B lights come with suspension hardware: two V-hanger brackets and two 36 in. chains.

Lights with built-in LEDs last longer, are more efficient, and generate less heat than fluorescent lights. They emit a neutral white light often found in workspaces. All have a lens that disperses light evenly.

Lights without bulbs work with tubular fluorescent bulbs (sold separately).

Lights with an aluminum housing are lightweight and resist corrosion better than those with a steel housing. Lights with a steel housing are more durable than lights with an aluminum housing.

Illuminate harsh, wet areas, even outside in extreme weather—these lights are often used on ship building ports. Rated NEMA 4X and UL marine listed, they’re sealed against heavy rain and washdowns, and they won’t corrode from salt water or cleaning chemicals. They’re also IP rated to stay sealed in dusty conditions. And with a durable glass lens, they’re rated IK08 for impact resistance. They’ll work in temperatures from -40° F to 145° F. Bright enough for environments that require high visibility, these lights have a cool appearance that highlights white and blue tones.

A quick-connect mount lets you wire these lights to an outlet box without having to hold them in place. First, wire the mount to your outlet box with a 3/4" conduit connector. Then twist the light into the mount to lock it in place.

These lights are DLC (DesignLight Consortium) listed, so they’ve been tested to confirm their energy efficiency. They’re also CE Marked to meet European safety standards.

These lights are UL listed for Class I, Division 2, Groups A, B, C, and D for environments where ignitable concentrations of acetylene, hydrogen, ethylene, and propane occur infrequently, such as in the case of an accidental spill or failure of a ventilation system. They can be hardwired to operate on any of the voltages listed. They require a metal halide bulb (sold separately). These floodlights cannot be sold to California due to local energy efficiency regulations.
