Luminus CXM-32 Gen3 the next big thing??

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 $
 
@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.
 
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
 
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.

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

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
