About Brightness and Light Appearance

Find the right lumen level to brighten your space. Then, compare the way warm, neutral, and cool lighting affect the appearance of everyday objects.

Screw-In Base Floodlight Bulbs

R20

Medium (Standard Household)

Often used in recessed can fixtures and track lighting, these bulbs produce a focused beam of light. Brightness is measured in lumens; the higher the lumens, the brighter the bulb. Bulbs with a warm light appearance have yellow tones. Bulbs with a neutral light appearance are commonly used in workspaces. Bulbs with a cool light appearance have white/blue tones and are good for inspecting. A bulb’s estimated yearly energy cost is based on 3 hours of usage per day at $0.11 per kWh.

BR and R bulbs have wide beam angles that create broad beams of light. Their length makes them good for use in large can fixtures.

LED bulbs last longer and are more efficient than other technologies. They generate little heat and withstand vibration. Plastic LED bulbs are shatterproof.

CFL (compact fluorescent) bulbs are more energy efficient and last longer than halogen bulbs. It takes several seconds for them to reach full brightness. They contain small amounts of mercury (for disposal information, visit www.epa.gov/cfl).

Halogen bulbs are energy efficient.

Socket Base Vehicle Headlamp Light Bulbs

Brightness is measured in lumens; the higher the lumens, the brighter the bulb.

2-way bulbs operate at two brightness levels, as in high- and low-beam headlights.

LED Light Bulbs for High-Intensity Discharge (HID) Lights

Tubular Bulb with E26 or EX39 Base

Globe Bulb with EX39 Base

Mogul

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.

LED Light Bulbs for Hazardous Location High-Intensity Discharge (HID) Lights

For Bay Lights

Swap out the high-intensity discharge (HID) bulbs in your hazardous-location lights to lower energy costs. These LED bulbs are rated for NEC Class I, Division 2 locations, so they’re safe to use near combustible concentrations of gas. They last longer than HID bulbs and achieve the same brightness with fewer lumens. Match the wattage of the bulb you’re replacing. These are ballast bypass bulbs—install them in a socket that’s wired directly to the power source.
