I bought these off of someone on RC in the spring when I decided to give MH a try. They are roughly 14 x 14 inches. There's not rust on them and they aren't perfect but they will get the job done. I'm sticking with MH but just upgraded to bigger reflectors to get more spread. Not looking for much for theme just sps or chalice frags in trade. I'll toss in the floating canopy that I built for them if you want it.
