5000k 4' LED strip

by -

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.

Great Job

I believe this company knows their stuff. I have had a wonderful experience working with this company. Thank you for your hard work.

New standard in reproducing daylight!

by -

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!

Great customer service

by -

I have not installed the light yet so I cannot review the performance. The purchase experience was excellent. I called with a question about the product and they were most helpful and delivery from across the country was fast. Great customer service.

Lighting fast shipment

We have placed several PO's in the last three month and were impressed with the quick shipment and the customer service. Thank you!!

Cree Surface Light are really GREAT

by -

Light in weight,electricity, good colr, really bright. I see no downfalls of these lamps. Really pleased. Bees was GREAT had no 5000K in stock but somehow found one and shipped it with order. Can't do better than that! I gave 4 Stars because it's a TRUE review not Paid and I also think that there's always room for improvement. Otherwise I would have given 5 but to me that looks fishy when all are 5 star.
