These 12-watt LED T8 tubes are the energy-saving alternatives to 32-watt fluorescent tube lights. The 4' ballast-bypass tube light bulb can be used in direct-wire fixtures. It emits 1,600 lumens of cool or natural white illumination. Unlike fluorescent lights, this LED T8 tube turns on instantly—even in cold weather—and is simple to dispose of because it contains no harmful mercury. With a life expectancy 5 times as long as fluorescent tubes, the LED light 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.

Easy retrofit to upgrade to LEDs

Great product concept with all the electronics and LEDs packed in the tube. Converting old fixtures is simple. No new power supply needed. And the light output is great.
