Lamp fixture conversion method

A method of converting a lamp fixture of the type containing a mercury vapor lamp to a fixture containing a low pressure sodium lamp comprising the steps of

• a. removing the fixture from its respective mounting location;
• b. inverting the fixture and removing the fixture lower housing half and associated lens;
• c. removing the mercury vapor lamp from its socket in said fixture;
• d. anchoring the fixture reflector to the fixture housing to prevent relative movement between the reflector and the housing during the conversion operation;
• e. removing the mercury vapor lamp socket and any associated socket seals;
• f. removing any electrical components associated with the mercury vapor lamp operation not compatible with low pressure sodium lamp operation and replacing the same with electrical components compatible with the desired low pressure sodium lamp operation;
• g. affixing a bracket to the inner wall surface of the upper housing half rearward of said reflector, said bracket mounting a sodium lamp socket external of said reflector and aligned with the existing socket opening in the reflector and said bracket having a forward member engaging said reflector;
• h. installing a low pressure sodium lamp in its respective socket, whereby such sodium lamp extends from its socket external of the reflector to a point proximate the forward end of the reflector;
• and
• i. replacing the fixture lower housing half and lens while aligning the seal portion of said reflector with the mating portion on said lens.
