Great shop lights!

If you are looking for bright shop lights these are for you. I picked the 400W because at the peak my shop is 30’ and drops to 20’. Great coverage. Highly recommend

They're bright!

This light's been working great in my 2 car garage for 6-7 months now. Haven't wired up the dimmer, but between two of these lights, I have more than enough light to perform any task at night. They do get a little bit warm, but so far they haven't failed. The ceiling in my garage is only about 8 feet, but it's enough room to disperse the light evenly throughout the garage, and even getting enough light on the walls/shelves. Overall, I've had no complaints. They're great.

Nice HighBay Light, DIMMABLE!

These dimmable high-bay lights are great. Use a 0-10V compatible dimmer and you can really lower the power usage on these fixtures when you don't need the big light.
