Neither. I've been spoiled by individually powered and hung cobs that I can add/remove and raise/lower and angle at will.

You can make 'em for a little more than half what I paid for these pre-built. I only paid about $120 more than a single 6 COB china light with questionable drivers and older gen COBs so I can't complain.lol
