I thought so but just had to be sure. I didn't know if perhaps one had a slightly higher draw than the other so they wouldn't play nice on the same driver.
What is the best way to clean off Arctic MX-4 off of a chip? I'm going to have 16 of them to move from the center to the side of the 120mm heatsinks. I plan on just putting the two spectrums next to each other on the same heatsink.

you can use 3 x 1818 with that driver or if you use 1212 you can run 5 of them and max out the driver better for around 190w

Is there a meanwell I can drive 5x 1818's with?

I think 1818's are 50v so any driver with 250v would work the hlg-320h-1050 would work . I think you could do 6 on that driver.

http://cobkits.com/product-category/light-engines/luminus-light-engines/
i have some 120mm 3000k 80s already built and ready to go, so i put those on sale. the rest are 1 week or less to assemble and ship. im passing off a bunch of these to my buddy this weekend to assemble so hopefully in a week or so i have a bunch in stock in all colors

best at any wattage is probably citizen 3618 gen6 (~$50) and luminus cxm32 gen3 (~$47)
most cost effective at a given efficiency:
citizen 1212 gen 6 ~$13
luminus cxm22 gen 3 - $17
vero29 gen 7 and vero 22 gen7 are also right up there (i dont stock those tho)
any of the chips in the second list are 80-90% as efficient as the top chips at a fraction of the price

I know that. But if you space 6 COBs 5cm apart in 1x1m tent, calculator will still give you same amount of PAR W or PPFD.

It's pretty perfect for 30x30
PPF values really depend on a lot of factors, if it's inside a box with reflective walls PPF is going to be pretty similar to PPF values closer than 30cm.

Around 70PPF per 1212 at 1.05A.
