What I received had selector switches on the back which was not what was advertised. It wouldn't make much of a difference, but when I set all 4 to the same 3500k, 2 looked way cooler than the others. The spring clips were so stiff I couldn't get them out of the mounts to try different settings. Pretty disappointed.
