Please be more specific when telling people this. The voltage can only be adjusted on the a version of the drivers (eg hlg-185h-48a.) On the hlg-185h-48b or hlg-185-48 the voltage cannot be adjusted and it will run each board, strip, or cob harder until it reaches max. Risking thermal runaway.
Remember that folks, the a version can have a set voltage that will run each item in parallel at that voltage from starting with one item to as many as you can hook up until you reach max current. The more you hook up in parallel after you reach max current the current and voltage will start lowering until you reach the minimum CV voltage range of the driver. Once you drop below the voltage range of CV. It kicks into CC mode and has a wider range of voltage, until you add so many that it doesn't have enough amps to power the board, or drops out of the CC voltage range.
Not trying to flame you higgs, just trying to let people know this info.
