Is it made for constant current drivers?
Filament resistance varies greatly with heat.

Got a kick out of the ozone smell complaints. Ultraviolet light disrupts oxygen O2 molecules to create valent oxygen atoms that attach to other oxygen molecules to create O3 or ozone. Just thought it was funny.

They use either a capacitor or a resistor to limit the current. The filament is only used for starting, then the mercury vaporizes and the arc shunts re filament.
