Product Description

The Kosnic 12W LED 4 Pin DD Bulb is a retrofit replacement for a 28W CFL equivalent, using 47% less energy and, with a lifespan of 30,000 hours, lasting up to 3 times longer. This LED retrofit is non-dimmable, which may affect your choice if replacing a 4-pin fluorescent bulb. One of the benefits of the Kosnic is its option for plug-in conversion into an emergency light; a special socket and green LED is included for this purpose. The conversion pack is available separately from Lyco.
