LED bulbs offer outstanding energy efficiency, long-lasting performance and just-right brightness. Unlike CFL bulbs, LED bulbs deliver instant full brightness and are completely mercury-free. Featuring a standard, E26 (medium) base and the common A19 size, they're ideal for most standard lamps and fixtures when you wish to illuminate your home with soft white, warm light. With a color rendering index (CRI) of 80, they also provide excellent color accuracy. Choose LED soft white light for spaces like bedrooms, family rooms, dining rooms and entryways.
