These LED T8 tubes are the long-lasting alternatives to F32T8 fluorescent tube lights. The 4' ballast-bypass tube light bulb can be used in direct-wire fixtures. It emits 2,070 lumens of cool, natural, or warm white illumination. Unlike fluorescent lights, this LED T8 tube turns on instantlyâ€”even in cold weatherâ€”and is simple to dispose of because it contains no harmful mercury. The energy-efficient LED light uses just 18 watts of powerâ€”significantly less than the 32 watts of an equivalent fluorescent tube light. With a life expectancy 5 times as long as fluorescent tubes, the LED T8 tube reduces costly repairs, disposal fees, and the need for replacements. Price per bulb, 4-pack, 25-pack, or 50-pack. It's perfect for basements, offices, schools, hospitals, factories, and more.
