“I have a xenon lamp of the type used in flashes and strobes. You want to make a beacon keep steady on. Can you send me a circuit?”

 

Xenon lamps used in strobe lights and flashes were not made to light continuously. They can only operate in pulsed mode, because when driving they have an extremely low resistance, which would result in a very high current, practically a short circuit that would destroy the lamp. In normal applications, the discharge of a capacitor provides the current for a short time, just providing the energy it can handle. Thus, these lamps are precisely specified by the amount of energy they handle in mJ (millijoules) and not in watts (joules per second). Therefore it is not possible to make these lamps operate continuously.
