Ozone is produced by the 185 nm mercury line that is fairly abundant
in 253.7 nm germicidal mercury lamps. You get more ozone for your
kilowatt-hrs by a well-designed silent electric discharge. Remember
that ozone is exceedingly toxic.

If you want some hefty 254 nm Hg and shorter emission, look up Fusion
Systems' mircowave-pumped electrodeless lamps. They are hollow fused
silca frankfurters containing drop of mercury that wholly vaporizes in
use. Containing no metal or IR-absorbing anything, the lamps have
extremely small IR emission and truly whopping mercury emission
efficiencies.
