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.

Bi-Pin Base Miniature Light Bulbs

These bulbs are small, but very bright, so they're often used in flashlights and optical instruments such as projectors and microscopes. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.

Halogen bulbs are slightly more energy efficient than incandescent bulbs, but they generate more heat.

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

Flat Top Bulb with EX39 Base

Rectangular 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.

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.

Metal Halide Light Bulbs

Cone

Tubular

Blown Tubular

Replace the metal-halide light bulbs in your fixture.

Bulbs for open fixtures have a strong outer shell to keep them from shattering if they fail.

Bulbs with an EX39 base can also be used in E39 sockets.

Pulse-start bulbs restart nearly twice as fast as probe-start bulbs.

Bulbs that cannot be sold to Canada exceed local regulatory limits on mercury content.

High-Pressure Sodium Light Bulbs

Tubular

Replace the high-pressure sodium light bulbs in your fixture.

Bulbs cannot be sold to the listed areas because they do not meet local regulatory limits on mercury.

Non-cycling bulbs remain off at the end of their service life instead of repeatedly switching on and off, which helps prevent damage to ballasts and starters.

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

For Floodlights

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.
