Quick shipping and light as described. Happy with the purchase.

WOW! Cree LEDs rock!

The LED Fixture is well build (metal chassis) and the Lens mounts securely. We use these lights in portable equipment. The old plastic housing for the T8 fluorescent fixtures would break and fall off the ceiling during transport. These don't have that problem. The light quality and brightness is fantastic. Bee's provided great packaging and quick shipment.

These lights are everything I expected.

I need a lot of light in my garage workshop. As I get older my vision is getting worse so along with strong reading glasses, having a lot of light helps me see my projects in better detail. I bought six of these lights and installed them in two rows of three. This has really made all the difference. I ran the 120v wiring and 0-10V wiring for the Legrand Pass & Seymour dimmer myself.

Cree Lights and Bees Lighting were great!

Purchased these for a customer to install under an industrial mezzanine. Just what the customer was looking for. Great light!

Great lights, great service

My garage workshop was too dim for these aging eyes and the big box store offerings lacked high brightness and CRI. Working alone, it took just a few hours to install 6 of these 48� fixtures that are light-years ahead of old-time fluorescents, It is now a well-lit pleasure to work on my car or at the work bench. Bee�s was Amazon-easy to deal with and shipping was even faster. Lights were on my doorstep just 54 hours after placing my late-night order. The price was significantly less than HD or Lowes wanted for inferior lamps. You can�t go wrong with Cree's or Bee�s!

Great Pricing on CREE LED Ceiling Lights

Great pricing on very bright, low watt CREE lighting. Fast shipping. Would buy again.

Great Light with 0-10V dimming

by -

I had a small area in which to squeeze this light fixture. If I selected a typical Lithonia or Philips 0-10V fixture it would have been much wider and not fit as well. My only issue is if you have a normal junction box the assembled light (thickness) won't fully cover the hole. So, I still need to figure out what to put there to cover remainder of the hole. I wired this up with 0-10V wireless relay pack (EnOcean) and unpowered switch for dimming as well as an occupancy sensor. So, lights can go on with occupancy detection and I can dim it to whatever level I want. It is very bright so I dim about 50% down and get about about half the light output which is sufficient for most cases. The price is very good compared to the competitors with 0-10V capability. So, recommended if you want to use 0-10V dimming and pay the extra money. If I didn't need that I would have saved about $50 and gotten something without dimming. So far, great product.

Cree LS4 4000 Lumens LED Strip Light- love it!

This really lit up the garage. I can finally root around my work bench at night. I have a 2+ garage and the one light, with a 60 watt bulb on the other side of the garage, provides plenty of light. Although I may go overbord and get a second one. Appears to be very well made. I have no complaints, except wish it cost a little less.

Great fixture. Easy installation, clean

Purchase was easy and quick. 8' fixtures arrived in good condition with no damage. Bees Lighting was happy to accept the return of one 8' fixture, but I have decided to keep it since the shipping cost for a fixture of that length was about $150.00. Would purchase from Bees again, but would be careful not to over order.
