I QC'd both the corded and cordless version of this light a year and a half to two years ago. I still have a couple of them actually. At the time the corded was either 3,500 or 4,000 lumen I believe.
The overall feel and use is high quality, and the light is very bright white. The whole thing is one piece of aluminum with heat transfer fins on the back. Then a rubber cover for the edge. It's either the same light and manufacturer or the mold for the body is just popular and they use the same multiple COB array with a diffusing lens over it.
If this is a single COB emitting light source then it's a different light than I have.
I would have thought the price would be higher, not a bad buy.
