This circuit makes na incandescent lamp flash fast producing the stroboscopic effect. The speed is adjusted by P1 and lamps up to 400 W in the 117/110 V AC power line can be used. The SCR must be mounted on a heatsink. Font the 110/117 V AC line the TIC106B is recommended, and for the 220/240 V line the TIC106D must be used. R4 is a 10 k ohm need in some cases if the SCR remains triggered.
