i had one guy tell me tonight that 200 watts of cobs equals a 315 cmh or cmd bulb,, well i have never grown with a 315, but they say those are equal to 400 hid?,, if you asked me I would say no 200 watts of led cobs do not equal 400 hps,, but its not far behind, 300 watts surely is equal, but there are other advantages, back when I grew with 400 watt metal halides I had to replace the bulb ever crop, the time or 2 I did grow 2 crops per bulb , i could really tell it was much dimmer by the end, and I figured I lost money by trying to save moneySo its safe to say about half the wattage of cobs equals maybe slightly less equivalent in final weight dried trimmed cured of hps whether open reflector single ended or even double ended? But less heat...less ac....even less electric bill?
