Sylvania 13-Watt 4 ft. Linear T8 LED Tube Light Bulb, Cool White (25-Pack)

These LED T8 lamps contain no mercury, provide instant light and a uniform light distribution. Engineered to operate on existing instant start and select programmed rapid start electronic T8 ballasts, these lamps minimize labor and recycling costs.
