screws used to fasten the ballast were torn out, wrong size fasteners were used @ factoryrepaired and working fine.

I have a single-car garage that got a bit dark at the back, and I needed an alternative to fluorescents. When they mean "High bay," don't take that lightly. This is definitely a light that is meant to be hung higher than 10', which is where I have it mounted now. It's also not a light that projects outward much. There is glare, there is shadow; it is an extremely bright light for any homeowner. There are no deflectors, so don't expect the light to do much other than go down in circle. How big that circle is will depend on how high you hang it. Another big issue is these lights DO NOT come with any sort of mount. I don't believe I ever read that, but I may be wrong, so shame on me. I had to buy away from Amazon because no one seemed to have the mount. I have never seen a light that could not be mounted directly to the ceiling, which is what I needed. I believe it will serve my intended purpose.

very bright

Description shows these as 2’ X 4’ but they are only 2’ X 2’. Put out a great amount of light but size is not what I expected

I wanted something with a little more lumens for mounting 17' high in the center of my garage/workshop. I initially thought that they could be too bright but it does a great job from that height. The 22k lumens may have worked even better but I'll live with this for now.Solid metal construction but the driver on one of them was flopping around in the metal wiring box. Replaced the crappy stamped metal nuts but overall well built.They come well wired on the inside for 0-10v dimming with push in connectors, configured to easily allow you to go from one light to another with the low voltage wiring (I'll wire that up at some point in the future)I'll likely buy a few more of these. They are a little pricy, but I've seen less expensive ones that seemed too flimsy.

The pictures are from May 2015, when we installed 31 of these the lights(5000K) to replace 250 Watt MH lights. Worked well for 5 years @ 13 Hours a day. Bought from Home Depot at that time. Started dying one at time. Time for replacement.Bought these 4000K ones from amazon, and switched all the old ones straight out. Sure they will give service for another 5 yearsSaved around 800 to 900 a month in electric Bills

added around 30 to a large shop. much brighter than the T8 bulb fixtures we took down and less stress on the circuit

Needed an electrician to install.. would recommend getting the other version for more user friendly installation
