LiteSpeed,

When you get a cam, can you post pics ASAP? Please... These LEDs that your using... did you fabricate them your self?

You say you have about 1800 watts... of LEDs?! How big is the setup?
And about those fans and pumps... ??? Have you found that the LEDs have to be cooled? As to they last longer::: about what the average lifespan of your LEDs?

What wavelengths (nm) are you using?

Can we get some pictures? Pretty please...
