If people would just try straying from popular efficiency belief, more actually grew pot rather then argue over growing pot, then they would easily have made a 1000w DE replacement w/ the COBs they have now.
Crank up your COB.
Why not?
1) you'll yield allot more then you save on your punk ass electric bill
2) COBs will actually have penetration, even if you spread them a mile apart. (W/lens)
3) Who gives a shit If the efficacy is dropped to 1-3 years, your replacing it in 6 months anyways due to technology up-grade. Wouldn't you rather get the most out of your cob now, before its rendered (old, out of style)
I agree about why make these lights to last 5-10 years. Instead, why not make these lights actual 600-1000watt HPS replacements that can actually grow mad pot.
Orrrrrr, you can keep being sooooo efficient, in the mean time bitching & moaning about how your new LED light you bought or built can't grow like your friends HPS.
So many here never even used HPS, DE or any of the big hitters but all want to replace them. I don't get it. I know what these lamps can do, that is why I have much higher standards for my LED then so many i see that just want a 600-800 PPFD on the top of their canopy but absolutely nothing 6"-1' below said canopy.
Then they post of bunch of pictures of bud tops only saying: whatchu mean Willis?, look at my bud tops! LMFAO! Get real.
Math is great until it costs you $10,000 less on your harvest cuz you thought efficiency on your bill is all that mattered. Ha! It's all good, after all, you did save $20 on your bill trying to replace 1000DE with 1/2 powered cobs spread 1' apart.
It's all good though. You do you n I'll do me.
