Nice, is that an 8x4 tent?
Tell us about it :o You air cooling your lights? What you running for exhaust?

Oh neat, I didn't realize it was LEDs. When I have extra cash I'd love to do a LED grow in a tent with added CO2. I have some friends that are co2 converts, amazing results but hardly worth while when you consider the additional cooling costs when using HPS especially in tents. it would be sick as tits to crush 2gpw.

LEDs must run much much cooler than HPS. So at the very least they would be easier to manage with an AC vs. HPS. I didn't mean, no exhaust or AC at all.
Tent would have co2 on a controller ideally speaking, AC would be used to maintain temps and exhaust outside, and you would need a fresh air exchange however often ie. mostly sealed/perfect environment. I have a friend with a low tech co2 setup in his tent, he just has a regulator to pour disperse x amount of co2/hour and he figured out what the average ppms would be given his exhaust, room size, and air turbulence based on whatever manufacturer guidelines. I don't know how accurate that is but he's happy with the results. He also works for a place that distributes dry ice and tanks full of various gases so he just fills up for free.
4kw of light for most people = 250-350 cfm per 1kw in my case i'd probably be using two x 8" can fans = 500w and worse case for the AC would be 1100w so 5600w total probably have a small fan to exhaust the volume of the room twice a day or whatever is recommended. 5.6 kw /hr * 60days*12hours*$0.2=$806.40 in electricity alone under full ac/fan load. Whatever LED amount I found to cover say 1600 watt vs 4000 for "equivalent yields" (Granted this costs $7200 or would have from LEDgirl, then I'd just need to figure out the best/cheapest method of cooling I have no idea how it would compare. If I saved half of the electricity costs, I'd pay the LEDs off by electricity savings in just under 3 years! I still don't know how I feel about LEDs. In that time i'd probably also spend around $1500-2000 on bulbs alone.
What's the best priced / performance LEDs on the market?

Is there a standardized equivalent?
I'd probably, as it stands, get 600-800w in a 4x4 to see the growth potential.
Have you heard of Apollo? Very good reviews on amazon. They also seem pretty cheap on amazon, I can also get 50% amazon gift cards.
