This T8 LED bulb gives off 1150 lumens of light and takes advantage of hybrid dual tech, which means it can be plugged in and played or bypass the ballast for single-line voltage action. Switch out the old fluorescent and get an energy-efficient LED version -- it'll be a cinch! Installing it in a single-ended direct wire application? Just snip the existing ballast's wires, take it outta there, and connect 120-277V line voltage to the sockets. Easy-peasy!
