5000k 4' LED strip

by John W -

Arrived two days before expected delivery date and in good shape. Very solid construction - can be tricky to get the bracket and lamp assembly apart for installation. Once installed, super bright. Two of these easily light up a 20x20' work bay.

New standard in reproducing daylight!

by Kuan L -

The six 44W 5000K LS4 lights fill my ~26x40' basement with the closest thing to daylight I've ever seen. The light quality is "full" and not at all like the sickly green or harsh blue of FL and CFL of yesteryear. The lights come on instantly and make no noise. Just beautiful, useful, reliable light that truly feels like I just opened my basement up to the sky. Subsequent to my great experience with the LS4, I'm getting a single LS8 88W 8000 lumen 5000K lamp for my 1-car garage. The LS4/LS8's high 90 CRI is vastly superior to the 70CRI of the Haiku Work Light I was originally considering. Especially easy decision also given the Cree is less than half the cost of the Haiku light! I can't believe we can get such quality lighting. I grew up with fluorescents and that age is soon to be past: good riddance!
