Not happening.

I am not challenging you guys as you seem to think, but there is definitely a piece of knowledge missing.
You need to read, and no I'm not saying I'm an LED expert or a lighting expert, but like DH said, the comparisons you are looking at don't seem to be of equal wattage. When LED's and HID's are matched by wattage, LED's destroy. Why not try and find a grow of 450W of HID and compare it to stra8's 450W of LED. No comparison. What you are saying pretty much is that HID's waste alot, and you keep saying that. And what you also keep saying is that LED's do not waste, because like you said, 1000w HPS lights not fail, but 450w LED's do the same work, so meaning, that the HPS light is LESS EFFICIENT......If I'm too high or not enough, someone tell me, but that's pretty much what I've been reading.

ForgetClassC Reviewed by ForgetClassC on . Importance of 460nm red LEDs? Here is something very confusing to me. Many LED proponents loudly proclaim the need for 460-470nm red LEDs over the cheaper 630nm LEDs. I understand that this better coincides with the accepted chlorophyll B absorption peak. So far so good. LEDs veg very well given appropriate wattage & color. So far so good. LEDs do not compare (generally) to HPS flowering as far as yield. (Please - let's not go off in that direction here. Thank you!) Rating: 5
