Cree Series 304 canopy lights

[shadyluke]

So I lucked into 3 of these things brand new, in the box. Seem to run about $640 each. I am trying to decide if I want to mount them in my shop. I'm going to be putting a ceiling up this month and all new lights. I will be using 8' T8 fixtures but figured these may be nicer over my lift bay or across the back. They have some big heat sinks on them, is there any issues blowing insulation on top of them? These are the lights mounted over the gas pumps at Wawa's.

Looks like a hell of a light!
I would avoid blowing insulation over the tops of them. They say nothing about "insulation contact" rating. And the mounting options are direct, hook and cord or pendent. All of which indicate they should NOT be recessed into drywall with insulation above. Linsulation is going to void out any work the heat sinks are doing and they won't last. At that price, I won't want to replace one if I fell in love with it. Which you probably will!

Check what optics and what voltage they are built for. If you have the "UH" model, y won't be able to use them. And the price might change exactly how and where y mount them.

By the way......you ****!

I will have to fabricate my own mounts but I know I can power them. Hooked a 120v cord to them last night. Bright as can be.

It looks like you might have some different light levels available there with 3 different mA taps. Probably a dimmable fixture. Cant tell you how to take advantage of that though. Depending on which you use, you'll get anywhere from 4600 to 11,600 lumens.
Also, looks like they have in built in motion sensors.
And no, do not cover them with insulation.
Good luck

I have a wiring diagram at home. Even I can post later, can't seem to find it on the interwebs at the moment. How much space do you think they will need around them? I may be able to put a box over them to keep the insulation off of them.

I would think they are meant to hang in open air, with the bracket on the bracket fastened to the ceiling or structure. The heat sinks will do no good inside a box where the hot air cant get away if these will be left on for long periods of time.

Installation instructions are available here: http://lighting.cree.com/products/outdoor/parking-structure/304-series Click on spec sheet, then scroll down to installation instructions. They only show the fixture mounted in free air, so I wouldn't try to mount it in a recessed box. It has some pretty good sized heat sink fins on the back side that will need to remain exposed.

They are recessed mounted in the canopy over gas pumps. I'm not sure how much air moves in those but I wouldn't call it open air. I may try to put them in my soffits above the doors, they are vented. Plus I have 3 lights and 3 doors...win. The other option is to just surface mount them in the shop. Probably put these over the lift bay and use T8 fixtures to supplement the rest.

I've installed 100s of Cree canopy lights, mainly CPY 250, they get hot enough so in Maine last winter with over 130 inches of snow and temps colder than normal no snow was ever on these lights when they were on, in fact there would be a pool of water on the canopy around the lights and then 3 feet of snow . These are meant to be outdoors and mounted on a metal roof.

Nice lights for sure, but they are a fire hazard in a building

Here is the wiring diagrams.

The installation instructions show a junction box mounting bracket for surface mounting. Do you have the brackets?

No, they must have to be purchased separately as the boxes didn't include any mounting brackets.
