JC-LGL150W UFO LED High Bay Light 4 Pack, High Bay LED Light 22,500LM 0-10V Dimmable High Bay LED Shop Light, 5' Cable with US Plug, Hanging Hook, Safe Rope, ETL Listed for Shop Warehouse Barn

They worked great in my 14 foot tall shop and put out a lot of light.

This light is bright!When I first turned it on, I thought I was being abducted by aliens and now I can't go in my workshop without sun-screen!Seriously though, it's very bright and seems very well made. Mounting it was a snap - I just used an eye bolt and ran an extension cord to it through some more eye bolts.It has a massive heat sink but never seems to get hot nor does it heat up my workshop.This a commercial grade light and so far, it's survived the winter, spring, and summer in my workshop. I think the heat-sink will help it last a very long time as excessive heat is typically what does in most LED lights.I'm orderings more just as soon as I get some more sun-screen!

BEST THING ABOUT ITEM: very brightADDITIONAL LIKES: does not emit much heat given brightness, easy to hang, big heat sync, heavy duty construction, 5 year warrantyWORST THING ABOUT ITEM: appearance not aesthetically pleasingADDITIONAL DISLIKES: no built in remote controlCOMMENTS (Function, Appearance, Quality): This is a well built, heavy-duty warehouse or shop LED light. It is easy to mount as it includes a built in aluminum hook from which to suspend it. The hook as a set screw you can use to close the hook to prevent it from detaching. It also contains a 2 ft safety cable in case the hook fails or is circumvented. It comes with a 5 foot long cord with a 3 pronged plug. It also has a short pair of wires to which a switch/dimmer could be attached.Though it is designed for high bay usage, I have it hung 11 feet off the floor above the lathe in my shop. I was concerned it might put out a little too much heat that close to the work area, but thermal measurements revealed there was very little change in temperature at my height. I’ve enclosed three images of my wireless thermometer readings. The first is of the ceiling area with the light off (64.3), the second is of the light itself while on after 1 hour and pointed directly at the source (94.8) and the third pointed at the ceiling right next to the illuminated light also at the 1 hour mark (64.9 - image shows the memorized reading after measurement was taken since I was holding it straight up from the spindle to take the reading). The work area remains quite comfortable and is very well lit. I have it plugged into a remote controlled outlet to toggle it on/off from the work area.Naming it after s UFO is fitting as that is how it appears with its well segmented high aluminum heat sink. It has a nice sturdy feel to it as a result. A switch that is protected by a silicone plug allows you to chose between 150/200/240 watts thereby adjusting power consumption and light brightness. The light is incredibly bright at all settings, but I have it on high. The company doesn’t provide any coverage estimates, but I estimate if mounted at ~10 feet, it will easily light a double garage.MOST SUITABLE FOR: anyone wanting bright focused lightIS IT WORTH IT?: Considering the performance of the light and the warranty, probably. The ~$90 cost seems a bit steep, but you get an incredibly illuminated area for a prolonged period for that price.*PRECISE RATING: 5 (the five year warranty helped soften the blow of the price, so no deduction there)RECOMMENDATION: I can highly recommend the 240W light mounted at least 9 feet of the floor to brightly illuminate any work area.(As always, I will report back if there are any durability issues with additional use.)*Rating scale:5 = exceptional in several characteristics, happy to have it, definitely buy again;4 = excelling in at least one characteristic, would probably buy again;3 = average overall, would consider buying again;2 = low end merchandise and/or service, but somewhat useful, not sorry, but would not buy again1 = not worth the time or money; sorry I bought itCharacteristics considered: Presentation/Packaging, Quality, Craftsmanship, Materials, Functionality, Utility/Versatility, Instructions, Ease-of-Use, Comfort, Value.

I have had many issues in my shop with lighting. First, I had 12 regular light bulbs that constantly blew and give very little light. Then I got 10 used LED two row lights that that really lite the place up but didn't survive the cold after the 2nd year. Thought I'd try these. Right off the bat they are not a bad looking light. Easy to put together. Simply twist the hook into the base. I already had a couple eye bolts hanging so I used them to hook the light to. The hook has a screw through it to keep it from coming off, very nice feature. I hooked mine on the eye bolt then screwed it to the base. Also, there is a set screw to keep the base from coming off. This light actually had a 110v plug on it with a 5' cord, nice but I cut it off to hard wire it. With the light hanging and wired I flipped the switch and got nothing. About 2 seconds of staring at it wondering what I had done wrong I was blinded. It came on all of a sudden and I found out that this light very bright. I found on the side there is a rubber cover that you remove. under it you will find 2 adjustments. They both adjust the brightness just in a different way. At this point I am very satisfied with this light and fairly certain I will buy more next spring IF they hold up through the winter.

This light puts out a lot of lumens. it illuminates my large 2-car garage easily. Just plug it in and off you go. It would be a better buy if it had an on-off switch, or if the instructions included compatible dimmers. It comes with leads to attach a dimmer but doesn't say what dimmer will work, except for 0-10V, which is meaningless to me. The included mounting hook and hanger wire make mounting easy. Just mount to a stud or appropriate strength drywall hanger. The construction of the light is sturdy and should last a long time, if the leds don't give out.
