Ultimately the driver you choose will depend on the total amount of volts(v) is needed by the series of COB LED you are wanting to power.\ If I could get some advice on a configuration it would be great. It is 4 1818 3500k 80 cri and 4 1212 3000k 90 cri. Using the light engines.With 2 drivers Not sure about driver's yet but don't know if I need to run them soft or hard and what efficiency I can expect. Want to shoot for the 40 or so watt sq, ft. range . The 1212's will be mainly supplemental. Hoping to get some feedback on this. brindle123
For example a series of 4 clu048-1212 diodes needs at least 138.4v from the driver to turn on. (34.6v per cob x 4= 138.4v) WIth this example in mind the 200 watt(w) Meanwell HLG 185H-C1400 driver at it's maximum output can produce 143v to power the series of 4 COBs with 4.6v to spare. Another 200w driver, the HLG 185H-C700 has a maximum output of 286v
Although most COBs are more efficient with lower operating temperatures, running a series of COB diodes soft or hard is a matter of personal preference.
With your current desires in mind you will need to a driver that draws 150-160 watts from the wall that can produce enough volts to power the series of diodes you want. An example of a 150-160w driver: Meanwell: HLG 120H-C series.
Just for the sake of information: Trying to power a 36v COB in series with a 34v COB usually won't work. Within this web forum and possibly others, Meanwell brand drivers are typically used but definitely not a requirement.
