Hold out for some of the "do it yourself" LED guys to show up. They can tell you how to build your own COB for a low price and actually get a quality product. If you use the search feature and look for "quantum boards" you'll probably find a ton of threads on the subject.
Look, with all due respect, those are shit lights. They just are. You're throwing good money after bad and they're not going to be that much better than the cheap light you already have.
If you can't afford an actual improvement, why bother throwing money away? Just wait until you can afford a decent light.
Mars hydro has great lights at a budget price I have a 196 reflector which has been great also have a viparspectra 300 and a kind xl750 kind is the best by far but expensive mars hydro has been great on veg and viparspectra is only used for supplemental lighting far more blues than reds.
