Potentiometer needs to be attached to a B series driver to have full control/safety dimming down to 10% of cob power.
Speaking of, @CobKits are You going to be restocking ext pots/knobs?
Thanks
You might be able to use a push connection. Wago connectors you just push the wire into a hole, and latch something too crimp it. Make sure you get a potentiometer with pre soldered wires compatible with itWish there where some with wire pre-soldered on. I can't solder anymore, I shake like a pain mixer...

wiring in seriesWhat am i doing wrong :/ ?
Thanks, upon wiring in parallel it did work.wiring in series
you need a driver capable of ~200V to run 4 cobs in series
that driver can run any number of CXM22 but they need to be wired in parallel so the overall voltage required by the cob array is a match for the ~50V the driver provides
Anyone know where I can find a decent price on ans Apogee MQ501 PAR meter? Seems pretty hard to find other than Direct from apogee
This is what i have chosen with your help. will the leds get me through vegetative and flowering stage? thank youif efficiency is your criteria

about $350 you just need to build a simple aluminum frame that we can talk you thru
They are nice mate the first one i like the most think ill go for that one. Heres my parts list for when im ordering except for the wires, reflectors and cob holders. Do you think i have everything?
If you check out threads here where they measure the light that their fixtures produce (in a grid pattern), you will see that they always have a hot spot in the center.Hi mate im thinking of going with 8 x citizen 1212s to cover my 100cm x 100cm tray. Im just wondering what sort of frame to build for it. Any help appreciated thanks
you need chip holders (bjb or ideal) as well as thermal interface material (either 8 pads or a 4g tube of arctic silver)They are nice mate the first one i like the most think ill go for that one.
