Luminus CXM-32 Gen3 the next big thing??

[john0000]

So I have ruffly 40 par watts and 33 heat watts at 1400ma .. so I would one for every sq/ft would be ideal ..

 

[bassman999]

Vf is irrelevant to efficacy comparison, no?

My point is that one cob pulls 40-50% more watts at same current.
Really saying to compare cobs at a given wattage not current

 

[CobKits]

yeah that was just an aside i guess

point being at a given efficiency cxm is way out ahead in deliverable power and way way out ahead in par per $

Cant wait to get mine going and reap the rewards of the new technology

@CobKits

Do you plan on selling any pre built frames for ease of building? Kind of the last thing I need to plan out. Would be cool to be able to buy a piece of sheet metal with holes for the engines.

 

[CobKits]

yes its been sorely needed but i dont have a timeline just yet

 

[john0000]

Do you have an efficiency chart you can post @CobKits

 

[CobKits]

i can post my own measurements- i dont attempt to correlate them to efficiency %

you can generate tables from luminus calculator if you compute LER for a given spectrum

 

[john0000]

Thank you

Now I'm getting into the details on my planned cob build. Spring is coming, and I don't foresee any other cobs coming out that will be better than the CMX22's

4 x 2ft grow area

CMX22 3500k

6 @ 1400ma with 163mm pin fin
OR
8 @ 700ma with 120mm pin fin

Can someone show me calculations for PPFD, efficiency, and total watts? Not sure what way to go.

I'll take pictures when I get to building

I am building a light for the same area, and will be using a dozen CXM22 at 700ma.
Actually 10 cxm22 and 2 CXM27 that I already had lying around.
Ill be buying more cxm22s if I like them

That's so many lights!

You using pin fin heatsinks or bars?

If and when I get a bigger grow space I can use different drivers and push at 1400ma
I use 2 per 8x8 bar style on 42" long frame and 7" fans between them for canopy and that pulls air around heatsinks also.
My build skills arent the greatest, but after I build it Ill post a pic. Might be a while though with my stupid back pain.

Thoughts on cxm32 6500k 70 cri

you cant buy less than 300 of them

 

[john0000]

60 is the order min

 

[john0000]

Avnet has them

 

[CobKits]

interesting, ill get in touch with them and see if i can get these in smaller quantities in colors we want

 

[CobKits]

cxm27 are good chips too but it sucks theres no good holder options

They left me hanging on samples of the CXM32, they offered then never came through.
I was willing to pay for them and maybe they thought I was asking for free IDK.
I decided then to just get the cxm22s from Cobkits
