Avoid this light like the flu. First, there are 65 separate pieces that require assembly. There is a half sheet of instructions. This chiefly tells you how to wire in the unit. The rest of the assembly is all guesswork. If you are mechanically inclined, you will, as I did, eventually figure out where everything goes. But this literally took hours off and on over several weeks. The unit comes with three suspension cables that must be attached to the mounting plate. Because of poor instruction materials, you do not discover that once the cables are fed into the mounting plate, they cannot be pulled back out during adjustments. You have to disassemble the suspension mechanisms and pull all the cables back through, then reassemble all three. This is insane! Unless you enjoy self-flaggilation, don't buy this light.
