I called my local HF and they had 7 in stock. So I figured for $19.99, what the heck. Printed the $10 off coupon and picked up 4 (limit of 4 on the coupon) for less than $80 (before tax). Figured I would unbox 1 and see if I liked it.
I'm actually surprised at the construction. This light is very light in weight at slightly over a pound. The "bulb" area is mounted to a single piece extruded aluminum shell that is very well made. The plastic shroud over the LED's is not flimsy and is frosted to aid in light spread. There is clearly a good sized circuit board inside as you can see the screws where it's mounted. Manual says not to mount directly on drywall, but I don't see that heat would be a problem in the time I let one run on my kitchen table. Yes it gets warm, but not hot, and you can hold it in your hand all day long from what I observed, so heat does not appear to be a problem. The construction is clean, and looks very good. It's a lot better than I expected for $20 and most likely being China made. It is ETL certified and stamped that is is made to UL standards (but I presume it is not UL certified). Not a sign of flickering, no hum or noise at all. Even tried a video of the light to see if the camera caught fast AC flickering as it sometimes does with fluorescents, but none seen with the LED. With there being signs of a control board mounted, it appears this is not a 120v direct drive LED setup, but is using a driver control board.
Not sure how to rate the light output as I don't have one of the other 4000 lumen LED shop lights to compare it to. It's pretty dang bright (single unit). I would call the light temp in a daylight range probably around 5k. Where I'm going to use them the ceiling height is about 12.5' and open floor joists above so the lack of surface mounting option is not an issue.
I did an unscientific measurement using a free ft candle app for my cell phone. My kitchen overheat 2 bulb florescent light gave a reading of 39.5 ft cd at table height which was 5 1/2' from the light in my 8' tall kitchen. So I laid the Braun light sideways on the counter and measured off 5 1/2' feet and took a reading with the same phone and app. Got 80.5 ft cd. So I'm pretty certain once I get 4 of these in the same area of my basement, there will be very decent lighting for a $20 fixture.
The power cord does come out the top of the light and there is no provision to chain multiple lights together. The power cord is a nice thick cord with a grounded plug on the end. Chain is decent quality. I will be using these in a switched outlet configuration so the pull chain is irrelevant to me. There is a stud mounted on each end of the top of the light where an "S" hook attaches the chain. You can see one of these studs in the last photo below next to the screw on the right side of the photo.
I have considered popping the control board end cap off, to see if I can figure out a way to direct mount these to the open floor joists above. However unlike the twin LED strip lights there is no space in which to drill for mounting once I determine there are no wires in the path of the drilling. With the light weight, I'm thinking just take a 4 to 6" piece of 1/8" aluminum and drill and tap two small holes in the light frame to mount the short piece of aluminum. Then use that added tab as a bracket to mount to the floor joists. Or keep it simple and just hang the dang things (which is what I'll probably do.
So for for $20 a light. I think these are a decent deal and appear to be better than the average Harbor Freight item quality. Of course the true measure will be how long they last before the control board frys.
