Possible dumb question about DIY LED and drivers

When a driver says it's output Voltage is 107-215V as long as I use 108V of COBs it's not going to harm anything, right? I plan on running them in a series and couldn't find anything about if there's too many extra unused volts being supplied by the driver.

If you are using a constant(fixed) current driver, then the listed output voltage is the range that the driver can supply the rated current. Basically, if the drive current is what you want to use for the arrays you have, then just add up the forward voltage of the chips @ that drive current and if that falls within the cc operating range listed it should be fine. I think the only possible benefit for trying to use ALL of the available voltage is little better efficiency of the driver.

a driver is a little less efficient at ~50% load than a properly sized driver closer to 100% load, but thats the only consequence. you wont hurt the cobs or drivers

Awesome, thanks! I do intend on expanding later but right now to save on funds I'm going to start with only 3 and ramp up as I get further into flower after a pay check or two.
