This 10-pack of 4-foot LED shop lights is built to light up an entire garage, warehouse, or workshop without flickering or interference, the anti-high-frequency, anti-RF design means your garage door remote and radio keep working fine nearby. Each fixture puts out 5000 lumens for bright, even coverage that makes the space feel as clear as daylight. A 48-inch connector cable links fixtures end to end, with up to 6 lights wired in series off a single 59-inch power cord with its own on/off switch, so you can spread the run further from the outlet with fewer cords. Inside the PC housing are 210 SMD2835 LED beads rated for over 50,000 hours, using a fraction of the power of an old fluorescent fixture while lasting years longer. At 8.59 lbs for the full set, the fixtures work equally well in garages, basements, workbenches, and small stores.
