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.

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

Flat Top 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.

Metal Halide Light Bulbs

Cone

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.
