We just purchased 10 100W CRN lights for our 100x100 hangar. To convert our 31 dying 400W Hid lights. Bypassing the transformer is the hardest part of the install. Bright is an understatement, lights are rated 6000-6700k so its a little blue. With a $4300 initial cost it will take us just 22...
Link fixed, upon research on their site they are infact single end. To me isn't a deal killer as it's just a wire nut away from making them single end. Which if more popular might be a better idea any way.
So I currently have 20 four bulb troffers in the garage and per the recommendation of the thread I was planning on using these.
