LED High Bay Light, 200W 20000LM Super Bright UFO High Bay LED Lights, 6500K LED Shop Lights, IP54 Warehouse Lights Area Light Fixture Commercial Bay Lighting Bay Lights for Garage Barn Workshop-10

A little hard to install. but works well

I feel like this light is decent for the price range. It isn't exactly how it described. To be honest I wouldnt put this in a warehouse. Its good for a shorter ceiling. If its too high its not as bright.

I was amazed how bright these lights are, with a pure white 'day-light' hue which really penetrates the darkness. I originally ordered them to mount them on my RV for night-time illumination, but I found that difficult because the bracket is too short to swivel the light 90 degrees from the outside wall, only about 45 degrees before the body of the light would hit what it was mounted to.These lights would excel being mounted into holes in a wall or ceiling, in fact, screw holes are already provided for this purpose. Just be sure there is plenty of ventilation behind them, as the heat-sink fins will get very warm during operation. They've got to breath.

These are pretty good little bay lights but they are not what they claim to be, which is 100W lights. The first clue is the claimed light output, which is 10,000 lumens. Most other 100W lights claim a light output of around 14,000 lumens. 10,000 lumens is more consistent with around 70W. The second clue is the size of the light, which is 8-1/4 inch diameter. Most competitive 100W UFO bay lights have a diameter of around 10 inches. This means that these lights have a circular surface area only about 70% as large as competitive lights, which is important for heat dissipation. That also suggests the power of these lights is around 70W. The third clue is the price, which at about $22 per light at the time of this review is around 35% less than many competitive 100W lights, and if cost is proportional to power in a certain range, that also suggests these should be 65W to 70W lights.Finally, there is the definitive test: the direct measurement of power consumption. I have a meter which measures the amperage drawn by a device; multiplying amps by volts yields watts. The result: these are 73W lights, which is completely consistent will all the other indicators.Evaluated as a 73W light, these are fine. They are nice and bright - 10,000 lumens, after all, is quite a lot of light - but not as bright as a 100W LED light should be. The light is emitted in a uniform cone, and I think the light will perform well mounted 8 to 10 feet above the floor. The build quality seems good, although the pigtail electrical cord - about a foot long - seems unnecessarily short. The price is fine for a 73W bay light.If these lights had been billed as 70W or 75W, I would probably rate them 5 stars. I subtract a star for claiming to be something they are not, and they are lucky to get that.

I've already added some true warehouse-style UFO high bay lights to my storage building (16' ceiling), and my attic storage (12' high ceiling). They make a world of difference in being able to see things. so now I got these for my regular garages (2 X 3-car oversized), two lights for each.The ceiling there is only 8 feet, and these are fine for that. It also helps that those are fully sheet-rocked, textured, and painted bright white to improve lighting. But compared to my others high-bays, these simply are not in the same class.For starters, they have way fewer LEDs than any of my others, and overall they are much smaller diameter, and much smaller actual lamp area (excluding the outer cooling rim). They are also way flatter. Not the same as those true UFOs for high ceilings. However, that's fine for where I am using them. Just know these are scaled way down from what you might expect.The features are also scaled way down. The ad lists "1-10v Dimmable, "Radar Motion Sensor", "5' Cable with US Plug", "3000K/4000K/6500 Dimmable". Perhaps on some of their higher wattage versions, but NONE of those are on this one. It is strictly 6500K, so NO 3000K/4000K option, NO 1-10v dimmer, and NO indication it will work with a conventional wall switch dimmer (so I'm not going to being testing that to see if it ruins it), and just a short connection lead with no plug.I'm not even completely convinced these are 10000Lm, although the general rule is 100Lm/watt, so perhaps - if they are actually pulling 100W. They are bright, but don't seem up to the same level as one of my bigger high bays that is also spec'd at 10000LM.I have to wonder why that other one has lots of tall cooling fin surfaces on top, while this doesn't. If its making the same light, it should be getting equally as hot. And it would then need just as much to keep it from thermal self-destruction. Makes me wonder.This is definitely a bottom-of-the-line bare-bones small height and diameter version. That works for what I plan to use these for, but it would not work for my other high ceiling locations. Plus I really prefer the option to set 5000K natural light in some of those areas for color matching. 6500K won't work for me there.Honestly, I'm not a big fan of 6500K because, to me, it seems overly harsh. But for my garage with cars, motorcycles, and various storage, I can live with it. And these do have a couple of things going for them: they are compact, so they can almost hug the ceiling, and they are low priced.As long as you know what you are and aren't getting, this might be the ticket. But just be aware, compared to other true high bay lights, these are more like a junior version. But at just over $22/each, for what they can do, they are a bargain IF you accept their very limited features, don't have a really high ceiling, perhaps need a light that doesn't hang down far, and need four of them.

I got these to replace the large CFLs I was using in my 3 bay car port. They are a little less bright than I expected, but still much brighter than what I had used previously. To install, I simply added a plug end onto the wiring and use a screw in adapter in the old light fixture. This made the installation a lot easier than trying to rewire the boxes that were 20 feet above the ground.
