Barrina 8FT LED Shop Light, 100W 15000LM 5000K, Clear Cover Linkable Led Tube Lights, V Shape Integrated T8 LED Lighting, LED Ceiling Lights for Garage, Warehouse, Workshop, ETL Listed, 12 Pack

Light weight yet rigid, great color at 5000K, and excellent efficacy/150 lumens per watt the best I have seen. These are great shop lights when mounted on a high ceiling, as the two rows of LEDs are at 90 degrees to each other, for a total 270 degree output. This type of wide distribution is great for reducing shadows. But I wanted to use directly above and close to shop table tops, and I was concerned that there would be a dark area below the lamp, as often happens with bat-wing type output I thought these might have. For this reason, plus I wanted to shield the high glare that occurs especially when mounted lower than normal shop ceiling heights, I mounted in plywood troffers 7” high and 15”-19”wide, with the side walls at 30 degrees.The result is very good, very even light output even 36” from the lamps which I have mounted about 11” apart.As for measurements, with two 8ft lamps I get over 200-foot candle on the table top, just what I wanted.In the photos the further-away overhead light is the regular Barrina 20W 2200 lumen lamps, 6500K, which is pretty good but the troffer needs to be deeper to reduce glare, I will probably add 6” wings. These are 4ft lamps at 2200L while the new 8ft lamps are 15000 lumens. Therefore one 8ft lamp replaces six of the 4 footers.After building this I wondered if the troffer wings were even needed for smoothing out the distribution, so I tested 2 lamps 11” apart but without the wings, and found that there was no darker spot in the middle when measure pretty close at 36” away, in fact there was a peak in the middle, even when measuring 1-lamp alone. So it appears that troffer wings rather than help fill in the center, they filled out to the sides for a more evenly lit table top.

10 on the ceiling and 2 above my workbench in a 24x24 garage. Pretty much like having the sun itself in the garage with you. No dark corners anywhere. They seem pretty well made. One was damaged fron shipping, I contacted the company and they said it should be OK to install it plus they refunded my money for the one and it works fine. Pro tip, use a laser level pointed to the ceiling to align all the brackets during installation.... especially if you are linking 2 or more together.

Did not use the clips because my shipping container ceiling is uneven. Hanging with two wire loops screwed to the ceiling. Hangs with a 2" gap between fixture and ceiling. Lights are bright but get way too hot to touch.

So I got my 12 pack of lights yesterday and took one out wired it up to a replacement extension cord plug and tried it out. They are definitely bright. Easy to install and will be easy to wire in my new garage. 5 stars would recommend.

I would give these a 5 star but 2 of the 12 were damaged. The box itself was fine so not sure what happened. The lights are super bright and easy to install. They seem well made. I already had 6 installed before I noticed the 2 damaged. They clearly were broken and was hoping they'd still work but they were only flickering. I could return for refund but at this point I can survive with 10 out of 12.

Using these lights in my studio. They are bright , however, I had to replace them after 2 years. The replacement ones seem to be much brighter and the clips used to secure them to the ceiling are much better than the original ones.

First off, this is a great LED brand. Own the 4ft one, hence the decision to jump to the 8ft option to be used for a larger secondary structure/building was simple one. Two orders, second one a replacement…both orders had 4 out of 12 LEDs in pristine condition. The rest were bent at the ends like pictured, or along the shaft in random spots. It is a shame that issues like this are caused from manufacturer’s bad packing and shipping standards. These LED lights were not simply dented, they were bent to the point of unreasonable. Amazon made it right, but this is on the manufacturer. Please make sure you inform the manufacturer- they have a great product, it’s a shame that packaging does not reflect the product’s quality.

Installed these 8’ lights in my pole barn. They are 16’ off the ground and provide a perfect amount of light for woodworking or doing mechanic work.Easy to install, and they came with a good variety of cables for various situations.
