Love the brightness, the 5000K spectrum, and the ability to wire 3 different ways.
I replaced my garage fluorescent lighting with these things. I love them. I love the just-right 5000K not-too-yellow and not-too-white spectrum.They're bright. I rewired my fixtures without the fluorescent ballasts, with them powered all on one end.Update: Dropped rating from 5 to 4 stars. 24 of the LEDs stopped working on one light. So much for the "life time of 45,000+ rated hours".
