    sure but they wont light up ;)

    maximum 4 before you run out of driver voltage

    Start here alex, growmau5 has a few vids that will help.
    That will help you to understand amps voltage and what driver will work for you.

    How big of space are you running?

    If you already have that driver you could get a elg-100-c1400 for the other 2.

    Or get a hlg-320h-c1400 if your using ideal holders or hlg-320h-36a if you're using bjb holders or plan on adding more cobs later.

    I do also have HLG-320H-48B but it does says 48V output, does it mean that 1226 does not fit at all?

    I have to connect them parallel with this driver but dont they burn? I mean 6 pc of 1216 cobs running at 320 W?

    No. You need a 36v driver not a 48v.

    Even connected parallel?

    I read from the description on cobkits.com that 48A driver, also works with 36V COBs like CLU048-1212 or CXB3590 at reduced total power output. What does the reduced total power output mean?

    i stand corrected. the Hlg-320-48a will work. Should of looked at data sheet closer. it will turn down to 24v if need be.

    Do I need to dimm the "B" version somehow to reduce the total power output? Or what does it mean?

    Do alot more research your going to hurt yourself. Watch all the growmau5 videos you can an then do another month of research before you touch anything.

    The driver will operate in constant current mode if you use 36V parallel cobs on a 48A driver. Power = Volts times Current. Decrease the voltage and the power follows.

    If i run 3 citi 1212 36v cobs on my meanwel hlg 240 -1750 instead of the max 4 cobs, will it run at lower amps from the wall than if i were running 4 cobs?

    Less cobs, more amps from my understanding...

    yes
    3 cobs at 1750 mA is less power than 4 cobs at 1750 mA

    Yepp, take a 6-8 CXM22 (50V) instead, they fit better to this driver.

    CXM22 are limited to about 400 mA/20W ea on a 48B

    What is about 1216? Trying to find this graph for lower than 48V, cant find it...
