The bottom line is this,,, if you have the money to buy a UFO then why not just buy a 400 watt hid or a 200 watt flouro? Leds are a waste of momey any if you look through riu enough you will notice that most grows that started with Leds either died out fast or had bad results. Imho it is a waste of your hard earned cash, so unless you have dough like that don't become a victim to the Leds...
