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.
