This one is for lettuce, the next one will be 6 strips at .9aI did something similar a couple years back using 4 each @ 22w 5000/3000k t8 led tubes to cover 2 x 4. It worked pretty well
I would tighten them up (closer together by at least half)
Very clean light. Where did you get that little carbon filter?4 x CXB3590 @ 1750 mA, 3500k. It's working well for me. The grow closet is 3' x 3' x 5.5'.
I will definitely try thatI would tighten them up (closer together by at least half)
My 2 cents worth, check out this thread: https://www.rollitup.org/t/bridgelux-eb-series-build.928676/page-3Bought a dozen cobs for my new tent 24"x48"x60"
Looking for a cob placement design for best spread and no hot spot if possible

This is a design I came up with, but I know there are better ones
Too late to change plans as I have the Dozen CXM22s already in my posession.My 2 cents worth, check out this thread: https://www.rollitup.org/t/bridgelux-eb-series-build.928676/page-3
The strips would work perfect for a 2x4. They are cheap and easy to cool.
Although the above thread uses Bridgelux EB strips, I just ordered 10 of the M-series C at 4000K from Arrow. Arrow's price and shipping are hard to beat. 33.6 blazing watts per strip at test. https://www.arrow.com/en/products/si-b8t341b20ww/samsung-electronics

OK, I have 8 Vero 29s in 2 rows of 4 over a 2x4 foot grow box and it works great. 1 cob per square foot and I shoot for 15 par watts a square foot. 3 rows of 4 cob bars would be VERY even light coverage and you could drive each cob even softer!Too late to change plans as I have the Dozen CXM22s already in my posession.
I know its overkill, but thats the way I like it
Running at 700ma then dimming as needed, but enough for a bigger area in the future
I have 12 Cree cobs in my other 2x4 tent and works great, but my layout could be better, so want to get it better this time. It seems even spaced still has more light in middle for some reasonOK, I have 8 Vero 29s in 2 rows of 4 over a 2x4 foot grow box and it works great. 1 cob per square foot and I shoot for 15 par watts a square foot. 3 rows of 4 cob bars would be VERY even light coverage and you could drive each cob even softer!
Yes I think that is better. So many cobs on the outside you don't need one in the middleI have 12 Cree cobs in my other 2x4 tent and works great, but my layout could be better, so want to get it better this time. It seems even spaced still has more light in middle for some reason
I have seen this for 8 cobs in a square tent to avoid hot spot center:

I just need to adapt that idea to 12 cobs in a 2x4 space.Yes I think that is better. So many cobs on the outside you don't need one in the middle

Seems like a hot spot on sides??
What about your tent? Is it silver or white reflective? You can download a lighting simulator for your PC, or just use photoshop with circular gradient to transparent and overlap them to see where your hotspots will be.x----x----x----x----x

It's my own production.What boards are those? Where do you get them?
Where do we buy? Hook a brother up!It's my own production.
I think I will go with 8 cobs to start with, and then decide after this run is over if I need to add the other 4 cobs.mylar
Going to bed and will think more in the morning
