With those big chips you only need 6 per light. Remember your going from 22.5% efficient to 55+% efficient. Cooling should be fine as long as your below the kinds original wattage. Your cobs are emitting a lot less heat too.

Yeah I gotta figure that out. I bought 8 - 1812 and 4 1818. Think the efficiency is the same?
The k5 750 which was supposed to be a 750watt hid replacement has a whopping 94.3 par watts. Don't have to do anymore math to know that things a pile of trash. To achieve the same light output as the stock panel you'll beat it with 2 cobs so take that into consideration when building it. Let me know if you need any cree's I'll drop some off to you.

Hey now that like of trash does me right. Might not be efficient but it works. I have to take the find the total heat watts to determine my heart sink size. I think I'm good but I'd like to run the numbers. That's why I was asking for the efficiency on the citizens.
I just not think you'll need it. Those 2 cobs produce more photons then the hole panel did
The clu058 1825 @1200 ma 3500k are right at 51% efficient
The clu048 1812 @650 ma 400k are 47% efficient
The 3590 @ 1400 am is closer to 56% efficient
Don't take the comment personal. The epistar in that rig is 22% efficient

Franken-light!! Your one crazy sob jupiter
That kind panel is about the size of my Amare and it comes with 6 cobs for a full 4x4. If you go with 9 cobs you'll be cooking plants
