Spectrum King 400w LED Grow

Started off 2 strains from seed. Night Nurse, and God Bud. Both seeds were planted directly into 7 gallon pots, and are under the 400w spectrum king led. I'm vegging them in half of my 8x4 grow tent. I plan on scrogging them both. One I'll keep under the 400w led the other I'll move to the other side of the tent under 2 400w CMH. New to growing, and new to posting on forums so bear with me. Here are some pics.

The bigger one on the left is the night nurse. The other is God Bud. Got both strains from bcbuddepot.com

I didn't know regular humans actually bought these behemoth lights! The babies look super healthy. Why are they so chunky? Do they use proprietary drivers?

Not sure what they use or how they work. All I know is they use Cree LED. The results are great. Those babies are only 19 days from seed.

I'm going to need some help with scrog if anyone knows anything about it I'm open to advice. I don't know when I should start topping, or pruning

Hey Mrpurps, keep posting, I am very interested on the results. I seen this LED light today in the local hydro store. It was on and was very impressing. They also had a 400W MH on and I measured the intensity with my lux meter (I know, it is not a PAR meter, but just to compare). At 12" the 400W MH measured 20,000 lux and the 400W LED was out of range (my meter measures up to 250,000 lux). The light penetration was fantastic. The shop owner has one at home and is very happy and just ordered a second one for himself.

The light is not chunky (it looks chunky on the Mrpurps picture, but in reality it is smaller than an HPS light with the hood.

You should have measured around the perimeter. @Greengenes707 obtained a PAR grid from someone who owns the light. It looked like it fell off sharply away from center. He posted it in the "new to LED" mega thread.
