I recently bought a few LEDS, one being the blackdog, the other being prosource worldwide,
and compared them against my ufo led lights from china... wasn't impressed by the expensive
american brands at all when it came to measuring light in the 400-700 range... the cheap guys
seemed to have same amount of lumens in relation to wattage but were 1/10th the cost.

here's the link to the latest i bought at 1600 watt

how do these compare to say a 1000 what HPS?

Imo no led compares to hps. 1000w double ended hps is the way to go. Puts off a ton of light and once your rooms are dialed in and you know what your doing, can easily provide 2+lbs per light of some AAA flower

Not sure what the exact cost is per light because I have a lot of other stuff running in the room (dehums, fans, ac, etc) but its around 1800 a month for a 8k setup. More than pays the bills come harvest.

I haven't seen it yet, if it were true every large scale grower would be buying led's and not every single 1000w de product on the market.

On what footprint? 4x4? If so id rather get 2x as much in the same space and use a few more watts. Try convincing warehouse guys that if we switch to leds, we can get half the size harvest in the same place, even if its using less watts

2x4... but my tent is actually 2'4"x4'4" so closer to 10 sq ft than 8.

People are always comparing 1000w HPS to a lower watt LED, usually around 600-640w which doesn't always give definitive results... but getting near equal results with +300 watts less is a big deal for some. I'm more into getting as many grams in as small a space as possible and consider 40w per foot and minimum 120 LPW by input to be the minimum as a 'hobby grower' otherwise there's no advantage over HID. Large scale growers might see advantage in going as low as 25 watts per foot, but the efficiency still needs to be similar to the larger HID bulbs. Most of the LED lamps that people have been suckered into buying have poor efficiency, in many cases comparable to CFL.

I would like to see watt for watt grow offs, either 600 vs 600 or 1000 vs 1000, but to my knowledge there aren't any yet.

If someone wanted to do a watt for watt with existing retail products, a 1000w -vs- 6 Area51 150w units. Spend $2400 on the LED and that can happen... which is why large scale growers are slow to adopt. Not just that but there are only a few LED lamp manufacturers that can compete in that category and a whole lot of people got turned of by cheap Chinese lights so there's that bad experience LED needs to shrug off. COBs are fairly new technology and only one company offering so far, soon to be two. In the next year or so there will be some interesting grow data coming in I expect. Eventually someone will do watt for watt grow offs. Beyond that it's just a matter of getting past the sticker shock.

People have only really been using them in a public setting like this for about a year or so, and no commercial company is building a COB based panel aimed at large scale growers. It'll be a few years before they catch traction with the large scale growers.

it took them a long time to realize that dehps was a step up i wonder how long cobs will take?
