studio color 575 (208v) M ballast compatible with studio color 575 (110v) S

SebSeb Registered User
I have a few ballasts from M units but I blew an S ballast and no S spares.
Can I safely use a studio color 575 (208v) M ballast in a studio color 575 (110v) S ?
Thank you.

    I recommend not attempting this. The M has a magnetic ballast and the S has the switching lamp power supply (ballast). The wiring is different and the igniter's are different. The M does not have lamp control. The lamp is on or off with power only. The S has lamp control through the logic board which talks to the lamp power supply. The faulty lamp power supply may be repairable and you can contact Light Parts about having it repaired: 512-873-7106
