yes I'm interested about dimming drivers too.just starting to get parts for my build,I definitely need to be able to dimm the lights when needed.I thought id need extra bits like variable capacitor,or some other driver?thanks..Ok so I have completed my build of my new light bar running (2) CXB3590 @3000K and (2) CXB3590 @4000K in series being driven by a Mean Well A series 1400ma driver. now I only have one question (so far) and that would be when I am dimming these puppies down what am I measuring and where? Voltage? Amperage? Par?.
This is the one thing that I am completely stumped by at this point. I got all the other build logic but this is escaping me and unfortunately I do not have a trusted source locally I can bounce this off of.
I can turn the little pot inside the driver up and down and see the light dim but I am unsure what to use as my gauge as to when it is adjusted correctly.
Sorry if this is a stupid question but I am stumped......
I know its shite,but I use the lux meter on my soil ph tester.just to get a ruff idea were the intensity drops off.I've heard there's par meter's available for I phone's now.still expensive,but cool.I'd love a proper one.I think the easiest method for electrical measurement is to plug into a Kill-a-Watt meter and work from there.

But what is important is the light on your plants so I'd recommend a cheap ($30) light meter (lux, lumens). A good PAR meter costs hundreds of dollars.
Well duh, neither are the COBs but I'm not letting that stop me!
;)
I guess my comment was based on the way circuit board pots used to be.
