Did all of a sudden the only way to get lumens is from vertically hanging bulbs.
For med patients growing larger plants, vertical lighting provides substantially better growth throughout the entire plant. For smaller plants, or a SOG or SCROG, more traditional overhead lighting would be preferrable.
isn't watt = heat?
So, 600W LED = 600W HPS = 600W CFL's = 600W HM in terms of heat output???
not sure on this, would like opinion.
One of the biggest differences between the above bulbs is in the amount of heat they put out, with the LED being the coolest, then the CFL, then the HIDS.
The watt rating refers to the amount of light output from the bulb itself. The entire unit may take up considerably more energy, running ballast and accounting for losses and such.
This is what makes the LED so attractive - the 600w that go into the light fixture, actually comes out as 600w of light, as oppsed to 600w of light and prodigous amounts of heat that require massive air moving equipment to deal with.

i would love to see a 300w led outperform a 1000w hps. id put all my lights up on craigslist for sale.if that was true nobody would be running 1000s anymore
This is completly wrong.
People still run HPS's because an equivalent amount of light coming from an LED would be prohibitively expensive.
Everyone will be growing with LED's in 10 or 15 years time.
The thing I find curious about slr's comments isn't his inaccuracy, it is his total lack of cost awareness.
I get about $1500 - $2500
per 600w panel. And spectrums/quality vary considerably in this arena. For quality grow LED's with the right spectral balance, expect the high end of that spectrum.
Running a dozen or so 600w LED's would cost well north of $20,000 - maybe close to $30,000 or $35,000. That's real money, even for prodigious pot farmer.
Running a dozen 1000w HPS's might cost $4000 or $5000, after cooling and duct work and shit.
That's why people use HPS's TO.
We can build cars that go 400 miles on a battery charge or a tank of compressed air, why are all we still driving around using gasoline?

Okay.

Note the nearly 1gram/1watt harvest ratio with
no fucking hoods and ducts and $250 fans the size of wedding cakes and shit.
LED's are the future off all lighting, the world over. From street lamps to desk lamps to indoor marijuana production.
