Same here, go LED!!! Plants grow under each type of light have subtle differences in thier needs. To be a fair I hope you are adjusting for these factors.
Its all good. How much good can you stand?

yeah, every 5 hours per 1K hid light is a dollar out of my pocket. With HPS and MH at the same time, that will be 6 bucks a day. Even if LED's do it for half the wattage, I can save 3 bucks at day at full blast. That shit adds up fast.

1) 120,000 x .05 (5% usable light in HID) = 6000 usable lumens
2) 23,000 x 1.00 (100% usable light in LED) = 23,000 usable lumens
The issue with LED has always been the intensity of the spectrum emitted, not the amount of absorbable light. By using a 3w or higher powered diode the required penetration is attainable to produce dense bud.
I have watched the LED race closely for about 3 years now... LEDs will win eventually and they are getting really close now. Just remember that there are many different grades out there, most of which are garbage produced in china!
can you cite any LED light made anywhere else? I believe hina has taken the lead on LED manufacturing.

A three watt led at that quantity can be more than a buck with the proper driver and shit. That leaves over 300$ for everything else, assembly, shipping and profit.
Dude, check digikey. They are a wholesaler for cree in the USA. The cheapest you will buy a 3w cree led for is around $3.00 (and this doesn't even factor in the more expensive spectrums!) each in mass 1000's quantity. 168 x $3 = $504 in LEDs alone. It is physically impossible to produce a quality 500w led light using 3w cree bulbs for anywhere close to $549

well LED chips are made all over the world, china has taken over assembly of the units from what I can tell. Cree leds (the led chips themselves) are made in the US, and are implanted in the grow light body in china.
There are some ebay seller from china putting out absolute cat shit led lights, using bottom of the line stuff. Then again, i bet the best lights on the market are assembled there. He'll my cell phone is from china and I f'n love it.

You are right, I was merely pointing out that with any product produced in China there are hundreds of knock offs that produce cheap crap.

My point exactly, there is no way that this company is assembling 500w 3w led cree fixtures in china and retailing them in north america for $549!

Fuck your right, It says they use cree for the 12K white. Oh well, hopefully they are a good off brand name led and I won't run into any problems. They are still bright as all hell.

stats that prove Ledbudguy right:
- Size: 18"X11"
- Number of LED's: 168
- Total Wattage: 504
- Lifecycle: 50,000hrs
- 6 Band LED
- Infrared: 730nm
- Red LED: 630-660nm
- HO Cree White: 12k
- Deep Spectrum Blue: 425nm
- Ultraviolet: 380nm
- Universal Voltage: 90v-240v

I guess that way he can say: we use cree leds *and not say we use All cree leds.
