First off it's great to see you back bro. Lots of talk about your short break throughout the forum. Well missed.
I do have a couple larger cobs in the mix right now. It's more of an experimental thing at a close friends place. Lights like the cmh being 315 watts or hps 600-1000 watts are spread out across a very large reflector. A cob is 28mm and gives a heck of a lot more light per watt. That's what the experimenting is about. I have personally done it and seen numerous people here under estimate the power of these lights. The meme war contest winner posted this.
lol it's the truth. I'm happy to offer these lights as like you said there is definitely a need for them. It's a great cost effective way to try the new tech, it works amazingly well, perfect for supplementing and powerful enough to grow on their own. The biggest benefit is the long term. Not only energy savings or life span and no need for bulb changes but how versatile. If I piled up every light I have bought in the past that I don't currently use it would be taller than I am. Where these will always have a use. Granted I may not need all 20 but I will always be able to stick an extra light in various places. Or add a tent a closet, warehouse whatever the space is. Meanwhile that pile of red and blue LEDs are still collecting dust.
Just hang it up and plug it in. 3 day shipping too. Not quite amazon prime status but close.
