GE's Direct Wire Sunshine T8 LED tubes replace 48-inch T8—1-inch diameter—fluorescent bulbs. They convert 48-inch T8 fixtures to line voltage. Direct Wire LED tubes wire directly to line voltage and do not require a ballast. Their slim size fit in the same fixtures as traditional 48-inch T8 fluorescent bulbs. Why make the switch to LED? GE's Direct Wire LED tubes are rated to last 50,000 hours. They provide long 22-year life based on six hours use per day, so you’ll replace less often. They use less energy than a 32-Watt T8 with nearly the same light output helping you save money on energy. And, they’re mercury free. Use Direct Wire Sunshine T8 LED tubes in commercial applications like specialty retail and print shops to provide cool, bluish-white light.
