\ 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
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.
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.
