Cob..what brand and type for me..

[Robbert alberts]

Hello..

This is my first post on this amazing site..
Keep it up! Loads of good reads.

But for me is still confusing whats best for me..

I what 3x3 cobs for 4 Alien xl rdcw pots.
So every pot gets 4 cobs ( a few shared )

I room is 120x240x200.. do lagre for the 4 pots .

Don't really fancy of putting a heater with them so need some heat off the cobs .

I was thinking of 9x citizen 1825c4 3500k cri80 and a 320/2800 driver ( 3 of them )
So I can run them at 100watt.

Or are there better cobs atm?

Citizen are good but look at the luminus cobs, cxm22 have a look at price and performance.

Found them already. .
Looks good for the price...

Lummen is a bit lower and they take max 125watt...

So I don't think they like running them at 100 continue.

I could get more of them and say run them at 50 or 75.

those are a good choice for 100W action.

if youre not super concerned about efficiency citi1818 or cxm 22 will do fine as well. its slightly above their range but were talking like only a few % down in efficiency vs say 75W per chip

 

[Robbert alberts]

Do you offer the 1818 as well?

 

[CobKits]

i have all 3 of those chips

Nice....

the smaller chips like cxm22 and citi1818 have better holder and reflector options as well. in the 100W range you could spend twice as much per chip on a citi 1825 and only gain a few % in efficiency. if you were targeting 125-175W id say 1825 all the way but the difference is smaller at 100W or below
