Yeah I guess you're right but lighting seems to far outweigh any other electronic device associated with growing marijuana. Things like exhaust fans and Variacs just don't seem to matter as much as lighting...and most don't cost nearly as much to invest in....for the small grow op/personal use growers, anyway. I guess I'd invest in a ChilLED if I could afford to....But then I'd worry that next year, Samsung or Osram, Cree, etc. will come out with an even more perfect chip...Or Meanwell will create some new kind of super efficient driver that will obliterate the old models. Not to say that the old models won't continue to work just fine to grow the weed...I have a bunch of old tech, too and it works as well today as it did when everyone was going crazy over it years ago.
Now they are almost antiques!
But when I see a knockoff that has all the new cool chips and latest stuff for a fraction of what a ChilLED light goes for...and likely will grow weed every bit as well as the ChilLED, it's a real temptation to try one or two of them. So I probably will do just that. But I also remember several years ago, when the cheap knockoff lights were being put down pretty hard and people were being advised to avoid them and buy something of a higher quality. Remember those days? Seems like the knockoffs have upped their game since those days....?
