I'm seriously considering ordering the lm301B UFO with Cree supplements from R2T... I think it would be perfect for my 2x2 that has 6 X EB strips 2nd gen for side lighting.

I can't speak highly enough about this Paradise Seeds Sensi Star pheno.
Although I dare not say I've got it ready or there'll be a queue outside my door.
Imagine if they were grown under real Samsung diodes........

I’ve been reading a lot of this thread butttt—it’s a lot.
I’m in a 4x4 and looking to possibly send back my two cob 240 watts and spending my money on Chinese quantum boards.
What would be the best choice of lights to fill up a 4x4 with plenty of light?
Also what are best lights for veg? Will 65 watt quantum’s work?
Lastly are the newer version quantum boards worth the money? or are the older diodes pretty much the same.
Thank you for any help. good vendor choice is helpful as well

I'm a noob. Which one of these two pretty little holes do I use to dim my lights?

You can fit 4 boards like this in a 4*4
Edit: these lights are white, my cellphone camera makes them look blurple.
These are the lm561b boards from Meijiu on Alibaba. You can get the Alibaba app and chat with Rita there. She hooked me up. Tell her Pablo Draco sent you. I paid $80 a piece for the boards add + heatsinks $30 each + driver's. You should be able to find Meanwell 600's at around $100 each. You'll need 2 for 4 boards. You can also go for the lm301B boards, but they are more expensive at around $115-120. Not sure the difference is that noticable. Then there's the shipping... But I've seen they offer free shipping to the US before.

How the hell is your camera fucked up to make photos appear like blurple light?

What COBs, with what driver? If you're running a decent setup, you may see little-to-no gain from switching to boards.

You would NOT want two 600w drivers in a 4x4. One (with appropriately matched boards) would be more than enough.

Thanks man.
My grow area size varies depending on plant numbers. It's usually between 4 ft x 3 ft to
6 ft x 4 ft ish. I've got reflective boards that I can move in or out.
2 x FOTOP 800 board kits with heatsinks will do a 4 x 4. 1 x MW 600h would get the job done.
3 x FOTOP 800 boards even better
4 x FOTOP 800 boards for a 4ft x 4ft would be perfect.
2 x MW 320H 48A drivers would suit the 4 board setup.
Wall to wall light lol.

That's what she gave me when I snapped the photo. Here's a better one:
Maybe the camera was picking up on some of the reflection off the colorful sound insulation that's on my walls.

Right third time.lol
It's a Tower fan or 2
Here's Soma's Somango from seed, 45 days 12 on 12 off.
It's under a Disco Board now, in the left hand side at the back.
It got so tall I'd to snap some branches over. Must be the skunk in her.
I had to raise the Gorrillas up 8" to even out the canopy
And 4 x RQS Royal Gorrilla that were under the hinflux strips until I moved then in beside the Somango about an hour ago.
So, I've the Somango and a Gorrilla directly under the Disco Boards to see if anything good or bad happens.

I have 2 cheap Chinese leds with (epileds COBs) and 3watt osram chips. Each 240 watt with veg and bloom switch. I also have a high pressure sodium 400 watt I’m basically using these as supplemental light in 4x4 grow tent. https://www.amazon.com/Hipargero-Lights-Indoor-Plants-Spectrum/dp/B075XSFB5X
I’ve done a lot of research and I finally decided to buy these a week or so ago and they seem to be pretty decent but they have 120° Lens. I asked Customer service and they told me they use these for (whatever reasons) I forgot. Anyways I can send these back if I need to but my mind is boggled at this point from all the information about lighting. I know I should’ve started out simple but did not do that. Do You think I should keep these and just remove the glass lens covering the COB? Or go a different rout. These are the 800 W version not the 400 in the link
I should have mentioned that I have cheap Chinese things from Amazon instead of just saying I have CO B’s thanks for any help
