Normally, stroboscopes, which are intended to emit short, intensive light pulses, operate from very high voltages. The present circuit works with LEDs and operates from 15-24 V. Of course, the diodes do not give the blinding flashes one associates with stroboscopes, but for many applications they give a satisfactory output, particularly if high intensity types with reflector are used. Very suitable is the Type GL5UR3K1. A drawback of these types of LED is that they are not cheap, but sometimes they can be found in second-hand equipment.
