Sylvania DIRECT WIRE Ballast Free (Type B) 8 ft. LED bulbs with Color Select are an energy saving alternative, designed to replace traditional fluorescent T8/T12 lamps by bypassing the existing ballast. This energy-saving product replaces 59-Watt T8, 75-Watt T12 or 110-Watt T12HO fluorescent bulbs, but by only using 42-Watt to deliver 5000 Lumens. The color of the light can be changed to 3000K, 4100K or 5000K via the switch on the product. These LED T8 bulbs contain no mercury, provide instant light and a uniform light distribution. Engineered to operate directly on 120-Volt to 277-Volt, these minimize labor and recycling costs. They can be used with occupancy and vacancy sensors for enhanced energy savings.
