Flouro's continue to out-produce LED's. Fact.
You have got to be kidding me.
Flouro's do not equall LED's at all, in my opinion.

Here is some side by side grows LED vs HID and we know HID is the best right now, but no flouro compares to either.
Seconded. LED's (at least with 0.5w+ bulbs) surpassed HO flouros long ago. The "fact" statement is laughable if you have tried growing cannabis with both. I use 134 watts combined to clone and veg *all* of my plants and that just wouldn't be possible with T5HO.
The cliff notes version:
LEDs are more efficient than T5HOs LEDs are more efficient than HIDs LEDs will out-preform T5HOs LEDs will not out-preform HIDs
LEDs are the best for cloning and vegetative growth HIDs are best for flowering growth
Last time I saw this guy talking about LEDs he cited a study from 1995 or something. Not going to read into this much further.

Most of them use 3w bulbs or a combination of 1w & 3w bulbs to keep the size down. Also remember LEDs don't need reflectors because all the light is extremely directional.

The bright future of T5HO and HID must be why the DOE is replacing 40,000 HID street lamps with LED fixtures in my city. Or why local governments have been doing this across Europe for years now. Your argument against LEDs is based on light output and you cite no cannabis-specific studies, so I'm interested to see how you spin this when they believe in the output and efficiency of LEDs for public safety on a massive scale.

Harry_Ba11sach said: I'm still not sure I agree. As a case study, compare Agmotes LED grow where he used approx 200W of LED power with my CFL grow where I had 250W of CFLs (although only about 100W was on a single plant).
I yielded nearly triple what he did
No offense to agmotes but cultivation skills and factors alone could explain the difference IMO. My 120w LED vastly outperforms 195w CFL (3x 65w Flourex CFL's) for comparison. Just like the ICmag thread we might be splitting hairs unless people try both and report unbiased results, but the fact that he said it was a fact is what I take offense with. This guy clearly hasn't cultivated anything under LEDs and is spewing hypothetical bullshit based on studies of drop-in T8 tube LED replacements, etc. He says getting two lamps side by side isn't the solution when in fact it is, lol.

DieselB said: Nor is their enough demand right now to drive prices down.
I disagree. The 120w I bought in January 2009 can now be had for 35% of what I paid and most other units especially UFO's have also seen their cost cut in half. Ebay might not be the best barometer, but there are thousands of led grow lights getting bids and selling every day there compared to maybe a hundred HID setups. Advertisers pay 3x the price on google adwords for LED grow lights and look at some of their keyword tool search data:
"led grow light" 201,000 searches "led grow lights" 301,000 searches "hps grow light" 27,000 searches "hps grow lights" 9,900 searches "fluorescent grow light" 22,200 searches "flourescent grow lights" 18,100 searches "ufo led grow light" 9,900 searches
The ones really driving the costs down are all the aerogarden types that never would have considered buying a HID setup but love the idea of LEDs and an indoor garden that doesn't generate heat or make any noticeable change in their electric bill. MJ growers can just ride the wave as prices go lower and intensity increases as opposed to doing 99% of the spending (like we do on HPS) and being locked in at the same prices year after year after decade with little to no innovation.
