Here is my second post asking for an advice. I'm looking to start shooting product. My kit is canon 50D, tripod, 24-70 L, 70-200/2.8 IS, vivitar 55/2.8 macro, spending time on ebay for a 24/3.5 TS. I want to buy a lighting kit, CFL. Budget is around 500$. After reading numerous reviews, for different lights I stopped at this kit Calumet Quattro Fluorescent Two Light Set - CF0003K1 - What's your opinion in this regard?
