Hi all,
I have just found a Coralife 175 w metal halide set...it comes in a 48 inch fixtures with 2 10 000k bulb(the person says they are Radium but i dont know bout that because i didnt see any words that said Radium on it but mind you I'm new to this hobby so wouldnt know a Radium light when I see it) it also comes with 2 actinics in the fixtures...its all wired up and all....They are willing to part it for $550...It is in pretty good condition...Still has warrenty on it..It is three months old...Is this a good deal????
