Hey all I'm gonna see what yall think on this one . I want to put a new light over my 20 tall so I can give my daughter my dual power compact 130 watt fixture. I'm thinking about a 150 hqi retro but I'm not sure if I'll need suplemental light or what type of reflector. I like the open top look and I'm kinda open to suggestions ( bulbs , ballast, reflector,ect) so just let me know what u think or have experenced with your set ups . Thanks again yall
