Overall the product is good, but why it's a 4 star and not a 5 is the fact it came with a broken bulb.

The material and design is cleaver and clean.

These do not fit a standard electrical box. I ordered three and one of them was DOA. I am not sure they will provide a ton of light. The instructions explain all the connections but the mounting method does not allow for connections that are standard in a modern home in the US. I installed mine after the return window so I will need to replace the failed unit. I would order these again as long as I did not need to install in a standard location and had the time to customize the mounting. Not for a novice.
