Hey there GC! I wanna build a flower light for my 2x2 and be able to dim as required. Thinking it's probably better to go big? More light bigger bud? I just want to make sure I'm reading things right, so for 4 CXB3070s a good constant current driver for that would be an HLG-320H-C2100B? Max voltage 156v, so over the 144v I need for my 4 COBs, which I want to wire in series, and have a remote dimmer so I don't have to fiddle with a screwdriver. Does that sound about right? I have a good heatsink which should be able to handle those COBs passively. Bonus question for the noob...What should I be looking at for a potentiometer? Thanks team!
Hey Doob. All your numbers look correct for your setup. The HLG-320H-C2100B looks to have onboard volt and current pots so you can set your max current/ volts off of those. I think i remember reading someone had the same type setup and was using an outboard pot and ran into issues.?, please do a search to verify whether this is true. I would recommend a 240v, 5 amp outboard pot at the minimum to cover anything that might happen. Safety first right. P.s. Might be cheaper to scavenge a pot out of a used 240 volt baseboard heater at the local scrap yard.
Hey Mad Scientist, thanks for the heads up! Maybe I'll rethink that pot. I'll have a bit more of a Google anyhow and have a good long think about it. Cheers man!
