hi thanks for the post, question on how you've wired or wiring your switch in the power supply? ive scrolled thru the post and did my research but still am stuck

ty sir..appreciate ur help

ty sanjuan, ive contacted Nuonan/Karen and am working to put an order for the 1750a models with dimmers. im still on the fence about 3070s vs 3590s here, but either way not a bad option. appreciate your help & time

ty for the link it helps!

ty grouch.. so the 1050ma would be for parallel, but then the total wattage per chip would be around 30, good for efficiency, but not so much for growth?

SO I can run a max of 3 36v chips in serial on that driver, but not anymore to exceed the max output voltage?

ok thanks guys that makes sense..unfortunately i just bought the last 2100a...but just so i learn correctly i have a few followups if you would be so kind to help...,, using the 2100a would only make sense to drive 3 cxb3590s really hard, but for efficiency the 1750a with 4 cobs would be...

im a complete noob journeying to build my first led grow light using the info on all the threads. ive been looking at the 240-2100a with 4 36v cxb3590s, and from my novice calculations, it seems like the right amount of power for the cobs for the incremental $10 price over the 1700a - but i...

thanks airwalker, why can they run only 3?, from the specs i thought 4 would be fine, although more power utilization from 3? and yeah, they're pricy, still on nthe fence whether to use cxb3070s instead for the price point... how many watts are you planning running a 1750 on 8 3590's?

hi green, im a noob looking to run the 240 hlg with 4 36v cxb3590s, maybe 2x this for a larger light, but im a bit lost as to the 240-36 model compared to the 240-1700/2100 models, what should i be looking at and what do you recommend ?

howard...thanks for posting this, i was thinking of the exact same cob/driver setup so curious to see how it's working for you, any updates? i'm planning on running 4 36v cobs off the hlg-240-c2100a, still deciding between the 3590s and the 3070s,just a few questions if anyone could help...
