I'd recommend the new area 51 lights over that. You could get 7 of their new 4k COB's for $1137.
All that blurple shit is outdated. If you wait another 6 months those Advanced LED's will be $150 a piece, or they won't have a website anymore. I don't know how they are the only one with blurple panels not dropping the prices. You can buy these blurple panels right from China instead of getting them from re-sellers, you can save substantially.
Advanced LED's are very very very overpriced for what they are. There is no way 800watts of Cree XML's are worth 2 grand. 2 grand in the new are 51 LED's will blow that shit away. Be like CFL's compared to HPS.
Last time I looked at Area51LED's they didn't have a price for the new units, the price is up on their site now but there's quite a wait time. Up to you man, but I would really advise against any blue/purple panel.
The tech honestly never should have been embraced like it was, people grew good buds sure but they would have done better with an HPS. Most the guys in the LED threads have used the blurple panels before and say the cobs just blow them away. Realstyles smashed his marshydro unit up with a hammer because of it
