Cxm22 questions

[oilfield bud]

What's up Riu. I'm new to this diy led thing but think I'm wrapping my head around it..... Kinda lol. But anyway what do y'all think of running 10 CXM22 gen 3 90 cri's of of one hlg600h 54b driver. Should be around 60 watts per chip right? Thank you for your input.

Good parts list. hlg600-52b will be operating in constant current mode so each cob will get about 52 volts and consume 58 watts.

Are you going to buy the 133mm pin fin heatsinks? https://cobkits.com/product/133mm-passive-pin-fin-heatsink-for-clu048cxm22vero-29/

Well... I'm still doing a bunch of resurch but if I'm going the cxms rout then yes. Ill use the 133mm heat sinks But now I'm stuck between roughly 30 cxm22s at roughly 1800w In a 6x9 flowering area or 24 gen 7 vero29 at roughly 2400w in the same space ran on 140mm heat sinks. I think I'm gonna make a separate post about it

I have 10 cxm22’s
I run 4 in a row at around 73 watts with hlg320 at 3500k
And 6 Cxm22 with 2 hlg240h-54b in parallel at 80watts 3000k.
The 4 lighter covers a 3x2 really nice and grows nice plants. The other 2 I haven’t used yet

Looks nice

I like them, check out my ongoing journal

A string of 4 in parallel works good on a HLG-240H-54B that puts them at 60 watts each.

Can be built to completion in about 3 hours

That'll work. For versatility, you might consider two lights powered by HLG-320 drivers.
Some good build info over at ledgardener.com

Is that what you ran in your 2x4

Yes, an 8 cob version run at 300 watts ish.

There’s more than one way to skin a cat
This works too. Mine pushes them a bit harder...

8 cobs total 300 watts? You’ve got great coverage with 8

 

[oilfield bud]

I'm wanting to make 3 fixtures with 10 cobs at 600w each. Maybe 4 fixtures

Total 480 watts at full power but thats too much for a 2x4 so I run it dimmed.

Well the way I am driving them they go best in strings of 4. So perhaps 12 cobs? You can always run them dimmed but get more spread. They run more efficient at lower power levels.

 

[oilfield bud]

Well I'm trying to max out 9x6 flowering area I was thinking 1800w in there with 30 cobs off of 3 600w drivers.

 

[oilfield bud]

I could swing 36 cobs if y'all think that would be better. That would be 47w each

 

[Renfro]

More cobs at a lower wattage = better spread and more efficiency.
