i got the 90w for $300 when it came out, but its old modle now. now they have the 5-ban leds i just bougth a 180w 5-ban led with a big disscount because this was my 2nd by from the same company. my room right now is a 3x3 but will be a 6x6 after this grow. keep in mind my temps where 95-100F* in this grow and their still doing good. the pics dont do justice. this company gives you 90days to try out their light if u dont like them take no questions asked. if u do a side by side grow with their leds vs. hps they will give u 50% off. if u do a grow log they will give u 25%off. hear is where i bought them from LED Grow Lights from ProSource Worldwide - LED Grow Lights w/ 5-Band Tri-Spectrum design.
