  • Thing is, I've found this driver at a good price and only one left in stock so I trusted my instinct and did order it already !

    Hope it was no mistake !!!
    Hahahah you lost me again !

    I have a sheet made by SupraSPL and I thought that the 3070 would require only 36,25vf when driven at 1050ma and 34,99vf at 700ma

    So for me 145V total @1050 and 139,96v total @700

    This driver goes to 148V so it should nicely handle 4 cobs at those current.

    Am I completely missing the point here ?
    Hi there !

    I think all those driver electrical specs start to make sense to me thanks to you :D

    I might have found the ideal one actually:
    HLG-120H-C1050B
    Specs are 155.4W 1050mA 74-148V CC IP67 Dimming

    For me it looks just perfect to drive 4x3070 @700ma to 1050ma am I correct ?

    Thanks for sharing your knowledge dude you're da man !!!

    Thanks! The HLG-120H-C1050B won't produce enough forward voltage to drive 4 CXA3070 as they require ~40v each. The HLG-185H-C1050B would work for 4 emitters. It's range is 95-190v
