thank you chunkyskunky! when you mean efficient for output do you mean voltage wise or wattage? or both? i built the frame today now i just need wire, is 16ga ok? im having trouble finding 18gauge stranded that rated high voltage.i plan to remote the drivers ten feet away and hopefully get it...

ok cool thanks thats def a good idea as monthly perpetual would be nice for once, but hey my drivers are the 250w, but what your saying is when i push 70v to that chip i get roughly 100w at the 1400ma? So altho the drivers are rated, i can only use so much of the wattage? Just wondering when i...

truly appreciate your input, im learning as i go, thank you chunky!

ok thanks guys! yea when looking at the data sheet for that driver it has a max of 420v, anyhow my biggest concern is efficiency of the power im using so i went with 70v cobs. but not using the drivers full load i lose efficiency? is it that much of a difference? would i have been better going...

Hey, what about running 6 of the veros on that driver? (68v) because it says it has an open circuit limited of 420v. i would get 80watts per cob? Thanks

Thank you, this is what im looking for, the driver chunky posted is ideal because the voltage almost matches perfect but at 2100ma i believe these veros will run too hot. Ok i did want ti use my drivers in parrallel series of 2 strings, to get a 700ma current. But, the drivers say 089-179v so...

ok the driver u mentions says constant current 280v but then the specs say 114-229v. this looks like the driver i need but its out of stock. if so pherhaps i choose to just do the 8 cobs with what i got, id be using 140v of the 179v. is this ok? thanks again

Thanks, yes im looking at that driver now, its pricey but only does 229v and 4 cobs i would need 280v? i found this one too the elg240-c-700a and it does 343v so maybe 5 cobs at around 50w, but whats with the 700ma, too low current for the 70v cobs? that driver i mentioned is cheap but it doesnt...

ok here it is, i done fucked up ordering the right drivers and need to know my options. I was hoping for a cob per square foot run at around 50-60w, but like i said i fucked up and need help. I bought 16 Vero 29 Gen7. 3000k 90 CRI 70V (heatsinks etc.) I bought 4 of the HLG 240- C- 1400b...
