You should buy a par meter. I don't think it's right that some of these cob manufactures here offer Par ratings based on equations. They sell lights stating they will perform with certain PPFD's but never actually measured w/ any type of meter at different hights. I find that to be very misleading.
Don't be one of those guys Reals. Keep it REAL like your name implies.
All I've seen from these vendors w/ so called transparency is them trading one set of deceit for another. Leaving much of the LED world to continue to not trust manufacturers.
Real readings from a real light meter is what's needed, for real.

I have an Apogee meter and a lux meter but that thermal imaging I don't have and it will show me the hot spots.

You can rent these at some Home Depots if you just want to try it out.

PPFD readings are easy. Some manufacturers are using PPFD calculated from theoretical PPF, this appears to be true, But the same cobs at the same wattage have been tested by plenty of folks par meters. Thats no big deal. Check out @Malocan's thread for some of the most comprehensive testing yet. 511W of CXB3590 in a 4x4 tent, average PPFD at different heights, comparisons, the works. It's a great thread. https://www.rollitup.org/t/spectral-lightmeter-gigahertz-optik-msc15.913239/

I'd love to see more data like this, instead of negativity, ego stroking, and drunken rants. Here's a 3D visualisation of some of Malocan's measurements I made:

How cool is that?

I want to replace my 1000W HPS with a COB set up but I want to make 2 of them for a 4x8 room. I'm guessing 4 COB per heatsink and driver? 4 of those for one 4x4 section?

Are there any DIY tutorials for this type of set-up that someone could link to me?
