Control unit for stage lighting fades out one lamp while simultaneously increasing light output of another with accurate tracking. Gate of silicon controlled rectifier SCR1 is driven by standard external phase control circuit. Interlock network connected to output of SCR1 provides complementary signal for trigger of SCR2. If lamps larger than 150 W are required, use largervalue for C1.-M. E.
