UFO LED High Bay Light 150W,22,500lm 0-10V Dimmable,5000K Daylight Shop Lights for Warehouse,Workshop &Factory,Includes 5-Inch US Plug Cord,Safety Rope&Hanging Hook,AC100-277V

Lights are bright but not blinding. installed in a 30 by 36 barn at 14 feet high. 4 lights [150 watt] was plenty. I have not hooked up the dimmer option but lights appear to be of vary good quality. wood walls not painted and a cement floor. If you had painted or white tin walls a dimmer might be needed.

I’m using 24 lights in my 40’ x 85’ workshop and super happy. Eight lights is plenty to see and do general work, but having the other 16 lights the place up like daylight. I’m running these on 240 volts in order to reduce the current and be able to run smaller wire. The only down side to it is that I had to buy double pole switches to cut power on both live wires; otherwise a few LEDs stayed lit on each lamp even with the switch turned off.Totally happy. Would definitely buy more if I needed more. Have about a year of use so far and no light failures yet.

I put 5 lights in my garage 30x40x12 and believe me all the light u will ever need

Exelente

I purchased 15 of these lights for my husband's garage and would not recommend. At first we were very happy with the brightness of the lights. After a few months several lights began to flicker or cut off. I was issued a refund for 4 that we were having issues with. After another 2 months we started having issues with more of the lights flickering and smoke coming from two of them. My husband checked one that was smoking and realized the panel inside was burning up. It would cost more to fix than it would to replace. The description says these lights have a 5 year warranty, but you can only go through Amazon for customer service. They will not replace the lights under warranty, but want to give issues over a refund. I was told that I would be charged a restocking fee for the return of all the lights. I have shipped the lights back and now I am being told it could take up to 5 days to see my refund (we will see if my money is returned and if I am charged a fee). My husband's business depends on him having working lights. I would not recommend these lights due to customer service from Amazon and advertising a warranty that doesn't seem to exist.

Update…Within two days of writing this review, I received a response from seller who was very proactive and immediately sent 4 replacement lights. Excellent customer service.Purchased 9 of these for a new 36’ x 44’ shop. The light brightness is very good. However, of the 9 lights installed 3 of them flicker and and 1 will turn off completely and then after awhile will turn on. Power supply to light checks out fine.

These are just what you need for your 40x60 barn/shop, I installed six of these in my 40x60 and I'm very pleased. I looked at the 150 watt that were a little cheaper but these are worth the extra buck or two. MY six lights are wired in with number 12 THHN stranded to a 20 amp breaker and they only pull 9 amps, super cheap to operate! And staying well with in the 70% usage range for the 20 amp breaker. These come with a convenient three prong plug for easy outlet installation, but I hard wired mine. Plus they have a 5 year warranty. Either way a very economical light. Highly recommended by me! SUPER fast shipping resulted in SUPER fast installation!!!!!!! Would buy from again! Thank you

Seriously wow
