These LED T8 tubes are the long-lasting alternatives to F32T8 fluorescent tube lights. The 4' plug-and-play (ballast-compatible) tube light bulb can be used in fluorescent fixtures with ballasts. It emits 2,300 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. The dual-ended LED light uses just 18 watts of power—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.

Easy plug and play

I bought 16 of these (4-4 packs) and was so impressed with the brightness and ease of plug and play that I bought 8 more. The shipping was fast, The packaging was excellent. The 4000K is a little cooler color than I anticipated but still "natural light". Of the 24 bought I had one that did not work and sending it back for exchange was easy.

Works great, easy installation, read directions.

Worked Great, and easy installation. About the only thing to be aware of is that these tubes have a "fixture side" and a "light side" and that the latter needs to be facing outward. A label on the fixture side helps with that orientation, but if you just slapped it up without reading the directions, you might be tempted to try and remove that label.

Replacing fluorescent tubes with T8 LED tubes.

Replaced four fluorescent tubes in garage, the led tubes were easy to install. The line on the tubs made lining up for maximum light easy. Right light color and brighter than fluorescent equivalent tubes.
