They are great lights and no plastic hangers or anything like that. Very well built and fantastic lighting and I have not put dimmer controllers on them yet but I am operating them on medium and have great lighting throughout my shop.
Great lights for a tall ceiling shop
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
Customer is very happy with the lights for now. Will see how long they last, before they have to be replaced. This is our first experience with your company, but may not be the last.
Great
Installed in a 2,000 sq/ft aircraft hangar with an 18” ceiling. The four lights illuminate the space perfectly- nice and bright!
Really good, light is bright and were easy to install.
very bright! Great for our gym
These lights are awesome, really turns night to day!!!!
Very bright Working well
Put these lights in my mom and step dad's building. Great to see with in the sun light, yes these puppies are bright love em!
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.
2 of these 100W lights lit a 16X21 wood shop up perfectly. Plenty of light.
Rugged and well designed. Great materials. VERY BRIGHT. These completely illuminate my basement and then some. Installation was very straight-forward. Very happy with the value of these lights.
I bought 2 black ones same specs, dimmable, hooked them up with a dimmer switch they work flawless, but not the white version for what ever reason, they are going back!
Bright Light
Super bright works great in the shop
This light is brighter than 250w mh. Super good value for the money. The install was just as expected.works as expected. Ver energy efficient
I removed the old florescence and installed these and what a difference. It is like a sunny day in my garage.If you are going to use the dimmer circuit read up on what type of dimmer switch to buy.
Lights work great but 6 week ship date is crazy

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.
Just installed them but like what I see so far.
