I installed at my garage , what a difference in brightness, garage now got more light per square feet than ever before. Excellent product and for sure more economical than the other ones. Usually use the regular T8 bulbs which are not to cheap, also no have to use the ballasts which are a real head ache when start troubleshooting and they are Xtra expensive too. Good.price and power save. Recommend a 1000. Bestway to safe money with electricity that are way expensive now.

Got these led bulbs to replace in fluorescent light fixtures we already had. You do have to remove the ballast in fixture to utilize led bulbs. There were no instructions with bulbs on how to do that, but on Wayfair site it did give brief instructions. We also looked at some YouTube videos showing how to rewire fixture for led bulbs. They worked great, much brighter light. Love them
