http://hydroliquidators.net/store/p...d=170&osCsid=61eedc5f598fc839662be20662f2f099 any experience/thoughts on this lighting system? seems like having the ballast contained in the lighting hood would make the unit too heavy to hang, almost... the dude at the hydro store said it was a solid system and he seemed pretty stoked on it... so yeah, thoughts, anyone??
