1. An ultraviolet radiation lamp system for treating a fluid, comprising:

  • a substantially sealed cavity comprising a mercury-containing material;

    a filament disposed in the sealed cavity; and

    an electrical control element in contact with the filament, the electrical control element configured to maintain a temperature of the mercury-containing material with respect to a predetermined temperature, the electrical control element comprising an integrated circuit containing an algorithm which maintains the temperature of the mercury-containing material by modulating a current through the filament based on (i) at least one predetermined fluid parameter of the fluid to be treated, other than sensed lamp temperature, and (ii) predetermined target temperatures of the mercury-containing material with respect to values of the at least one predetermined fluid parameter.
