Xenon bulb

for warning lights

Overview
Excelitas offers complete plug-in flashlamp solutions — lamps, sockets and integrated trigger coils — that can be configured for warning beacon systems. Multiple quartz envelope options and dedicated long-life electrodes reduce maintenance frequency and total lifecycle costs.

Triggering Methods
Depending on operating conditions, lamp design and glass material, Excelitas flashlamps use efficient triggering methods such as wire, silver lining, conductive coating or a band to ensure reliable ignition and consistent flash timing.
