While we're at it...

Is there a list of common LER / QER values for common COBs/LEDs?

If we had this we could post a thread for folks how to easily calculate their light requirements.
(Only knowing LER /QER for CXB3590 3500K 36V I don't see much sense doing this)

10x CXB 3590 3500K @1400mA
4x4' (120x120cm) = 956PPFD

This is PERFECT if you want to max your light (aka: close to 1000 PPFD for flower)

My calculation gives me a PPFD of 783 with that set up. It would take two hlg 240 1400 drivers to run 10 3590's... :)

If budget was no worry I would look at running four hlg 120 1050's, four 3590cs each at 60% efficiency. One cob per square foot in a 4' x 4' with a PPFD of 1,007 with wall/reflector loss... ;)

Argh..you are correct 1.2x.1.2 = 1.44 sqm. Sorry ;P

Ok so...16 cobs does seem like alot for 4x4 bloom tent but I am with it. Does anyone want to go in on a cxb3590 order? I imagine we can save $ if we order a quantity of 50+ cobs. Thanks for your help guys. My 1200w King Led is unacceptable. I honestly think it does ok but I am looking for efficiency. Cheers guys.

Just out of curiosity, did you ever happen to measure the actual power draw of your "1200W King light"?
Let me guess, 340W? Someone on another forum measured their "900W" light, turns out each of the 150x "6W" LEDs draws only 1.7W, so it's not more than your standard 3W Epistar LED, actually less per LED.

16) CXB 3590 3500k 680$
Or
16) CXB 3070 3500K 576$

4) Mean Well Drivers 300$

4) passive capable heatsinks (Heatsinks USA 5.88 profile) 280$

The bits and pieces, wire, thermal paste, screws, holders, reflectors, lenses, solder, heat shrink tubing all add up and none of that has shipping tagged on to it... :)

It is an amazing light but it comes with a price...

:) ; that price difference
I spent my $ $ on the 3590 the price is not that higher everything else costs the same
is $100 worth the extra that the 3590 offers ?

I'm not sure yet but because I only needed 8 I went with the biggest, hottest, coolest at the time... :) if I was looking at lighting a 4' x 8' I would definitely consider the 3070... :)

I think the draw is like half. Almost all led panels draw much less out of the wall then the advertised wattage. There is an explanation behind it but I do not recall.

Are you sure 16 cobs is not too many to cover a 4x4 bloom space? I feel like 10 cobs would be about the right amount.

I just yesterday read a thread by one of the pros (Supra or Realstyles) where they measured CXB3070/CXB3590 and it seemed as if both LEDs are performing almost the same when driven low/medium, say at 1400mA. Quickly going over the CREE tool, when I compare the two I see roughly 10% more lms for the CXB3590

Didn't we have that yesterday already? It was 10 COBs (3590s@1400) 789 PPFD, so 12 I am guessing for about 1000 PPFD. 1200-300 PPFD as with 16 COBs...I consider overkill and not worth the investment and running costs IMHO.

your meanwells do multiples of 4 so that could be one reason for the 16
but 10 will have u ordering 2 more
been there done that Had to order more i had 30 needed 32
for the 185 - 1400 meanies ie ; 4 per m/w
