In terms of light output/brightness/PAR, you may never exceed a 600w hps bulb. All but a few leds fail here until recently.
Its just you dont need anything like 600 watts ( well upto 650 with ballast ) to produce that amount of light anymore.
Forget Led, when did anyone jump with joy over CMH when it was claimed 315 = 600. Grow shops cant shift the stock.
So it follows that gram per watt has to be better with led.
Any seasoned hps grower hitting 0.8 would smash 1+++ under new led. That's all i would want to see. Its not about best light technology, its about best grows and best weed.
