The lights were used to light up a 30x30 warehouse with a height of 15 feet. The warehouse peak is at 20 feet and lights were mounted at a height of approximately 17 feet. Lights came with hardware for various mounting options. I used a total of 4 lights each rated at 150 watts and 5k color. A professional electrical service man was used for the install and since each light only draws about 1.5 amps each, all were tied into a single breaker. One switch controls 2 lights another switch controls the other 2 lights. Hoping to get long life and will update my review accordingly.

This light is amazing! I’m not quit using it the way it’s intended but serves its purpose very well. I mounted it on a tripod where my dual 500w halogen lights use to be so I can work on cars and such. I have a 3.5 car garage and it lights up entire garage, the pictures do not do it any justice. Another nice feature is you are able to add a dimmer to it, it has a lead coming out of it to do so. It would of been better if they supplied dimmer with light but all in all this is an awesome light I would definitely purchase another!

I installed one 150w in my shop, it likes a sun, super bright, buying more

Put 10 of these is a 40x80 metal building. Plenty of brightness !

I have been looking into high bay lights for my shop for a while. I bought one of these to try out. It has exceeded your expectations. I will be purchasing at least 5 more
