What would be the best way to replicate 1000 watts hps with cobs?

What would be the best way to replicate 1000 watts hps with cobs? like what parts to use and how many watts are needed?

Thanks In Advance.

Here is a very nice built, I believe two of this lamp together will be more powerful than any 1000 watts DE hps.

That's a bit less than a DE HPS but it would still be a good light, the one above at 600W is what you would want

Either the 600 watt if you're replacing a regular SE 1000 watt HPS.

If you have a DE Gavita or something similar, then you will need more power to replace it.
