I had a slight issue with a few lights out of the box (it’s an 8’ foot long box, let’s get real, things happen) I sent a message to the seller and they promptly got me taken care of. The lights are installed and provide an amazing amount of light for their size. Cast light very evenly and do not flicker in video recordings (important for some people like myself) I will say there is a slight humming sound that wasn’t expected but it is not annoying or noticeable unless the shop is dead quiet. When you consider the cost, the quality and the responsiveness of the seller it’s an easy 5 star purchase.Wish 1st order were clearVery bright light!I had a problem with 2 lights would intermittently would not come on and they took care of it right awayMy only complaint with these lights is the extremely light gauge strand wire used in the manufacture of the connector cables. The conductor being so extremely fine, frays and breaks when connecting to solid-conductor house wiring, and the wire is near impossible to solder.The plastic wrap around clips were very nice and heavy duty, only 1 per lamp two would have been perfect. The shop I hung them in has an air compressor up stairs and the little clips are just cheap, I would have bought the extra half round clips if available. Ended up making out of plumbers strap, made hanging much quicker and easyer. Also a few longer wips would have been nice. Overall lit shop up nicely.I've been too many years and I'm getting too old to try and see things in my basement. I had 6 100 W lite bulbs there. 4 of these light strips is more light than those bulbs. I can actually go down there and see nowPut 18 of these in a 30x30 pole building and it is perfect. I was surprised how light they are but dropped one from about 12ft and still works! Mounting brackets could be improved a little and some longer power cords would be nice.
