Get a TI smartlamp 600 with the TI Probloom add on. It is a 330w led that has 5w diodes and has a very good flowering spectrum in it also. Good for veg-flower. I think the website is http://www.ledinnovationdesign.com/sl-presentation-en.html .
Also, i use this is a 3x3 tent. Works good. Little to no heat.
