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.

Socket Base Vehicle Headlamp Light Bulbs

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

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

Tubular Bulb with E26 or EX39 Base

Medium (Standard Household)

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.
