Xenon Flash Lamps and Flashtubes

 

    Two of the most common electric light sources leveraging xenon’s properties are flash lamps and flashtubes:

 

Flash lamps:

 

  • High-powered strobe lights producing very short, intense flashes.
  • Used for professional photography, spectroscopy, lasers, solar simulation.
  • Contain xenon gas pressurized up to ~1000 psi with quartz arc tubes.
  • Energy stored in capacitor discharged through lamp to emit microsecond-long flash.
  • Can repeat flashes tens of times per second. Lifetime of billions of flashes.

 

Flashtubes:

 

  • Long glass tubes of xenon gas that emit a brilliant arc flash when discharged.
  • Used in industries like mining, lighthouses, alarms, nighttime construction.
  • Operate at lower pressure (<100 psi) but larger lamp size than flash lamps.
  • Typically one use but some allow repeated flashing.
  • Bright output up to millions of candelas covering large areas.
