24" T8/t12, 20 W, T8 Tube, 8 W, Bright White, 6/carton

GE's T8 LED tubes replace 24-inch T8—1-inch diameter—fluorescent bulbs using the existing fixture and electronic ballast. It's slim size fits in the same fixtures as traditional 24-inch T8 fluorescent bulbs. Why make the switch to LED? GE's LED tubes are rated to last 36,000 hours. They provide long 16-year life based on six hours use per day, so you'll replace less often.
