Ozone generation

Ozone, a colorless, odorless gas, is produced in small amounts by operating xenon lamps made of standard quartz glass. Avoid inhaling it, as it is damaging to the lungs over a period of time. All LTI xenon lamps, however, are manufactured using ozone-free quartz; this quartz effectively suppresses ozone emission, and the lamps are designated "ozone-free".
