The 660 is going to be a little. He made the 660 because I have been telling/bitching/showing him that a bigger panel to equally cover a 1000w is necessary and has a place in the market. I have had plenty of designs that will, based on the math, cover a 4x4 pretty fucking even across the whole thing. He couldn't do what I wanted, but with what was available we designed the 660 as it is now...4 units in 1. Not my perfect design but dominates a 4x4 like it should. He made a bunch of basically prototype and to him, he thought it would be like a beta test while the production got finalized. Well like I have been telling him everyone has gone nuts for it. Stanford bought all those proto's instantly. He had to not sell them all they wanted so he would have a tester and one for me. Those proto's were supposed to hold off the market till full production was ready. Basically they were gone before they were assembled and he is now behind again.
But the AT200 is ready and going. Nothing super new other than the chip and heat sink for them.
What I have been seeing in my garden and in the data from the par meter is that the lens too narrow focused, to totally benefit from the power of the new chips. at the normal height. Both light are performing and reading really well @24"+. At 36" the 660 is identical to a 1000w at center and 4x4, but does basically the same with a higher peak at 24". I think that a wider lens or would be able to capitalize the ability to run led's lower and get use the crazy peak numbers that the new AT's are capable of and still get that umol gain at the full coverage.
The best way to explain this for the 660 is...
@24" it does 1400umol center and 310umol at the 4x4(24"from center)
@36" it does 927umol center and 373umol at the 4x4(24"from center)
and 1000w digital hps(according to growershouse)
@24" it does ~880umol center and ~350 at the 4x4(24"from center)
But honestly I want to do it with a different meter. 2 random guys had their own par meters at the max yield show(1apogee, and 1fieldscout) and both were getting higher readings than AT's licore I was using.
With all that said I have recently learned some things about the AT lenses. The the 14 is actually a 28* and the 50 is 100*. I don't know why they are stated as 14 and 50 but it explained a lot. The new chip and the 50(100*) is pretty good and can run at dick high and still cover all the way. I think that new lenses will be the next step for AT.
