IP or NEMA rated, these lights have a sealed lens to keep dust and moisture out for protection against washdowns. All meet ETL or UL standards for wet locations.

Mount these lights to the ceiling with the included brackets.

Style C have a tubular lens that allows light to shine from all directions. Those made outside of the U.S. include power connectors to link two lights. On the same circuit, link up to 62 of the 20W lights, or up to 27 of the 50W lights. Once connected, the lights can no longer be dimmed. They also include cables for ceiling suspension. IP66 lights withstand high-pressure washdowns. IP69K lights withstand high-temperature, high-pressure washdowns often used in sanitizing. NEMA 4X lights withstand corrosive liquids and spraying water—including washdowns. IK10 lights have the highest impact resistance rating.

Replace the U-shaped fluorescent bulbs in your fixture or upgrade to LED. These bulbs are often used in 2'×2' ceiling lights. Select a light appearance to match your existing lighting. Bulbs with more than one light appearance have a switch which allows you to match other lights in the room.

Fluorescent bulbs contain small amounts of mercury. For disposal information, visit www.epa.gov/cfl.

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.

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