XBO lamps are short-arc lamps in which light is generated by a discharge arc burning in pure high pressure Xenon gas between two electrodes. XBO lamps have a very high colour rendering index and extremely high luminance. For this reason they are used for cinema film projection, high-end video projectors and in light guide systems, e.g. for endoscopy. This lamp has positive pressure even when cold. Please read safety/warning instructions before using this lamp.
