I think jorge has one of those on his 30L and everything is really happy with the light. He has softies, lps and some sps. Great polyp extension and nice colors. The only thing that I would reccommend is having seperate reflectors per bulb, I dont think this fixture comes that way.....but you can get those thu sam I'm pretty sure and I think they can fit in that fixture, but dont quote me on that. As far as what kind of PAR output it has as is, I'm waiting on jorge to get the PAR meter so we can test it. I think if youre looking for a T-5 fixture and dont want to be worried with a retro kit, this is prolly a nice choice.
