A fluorescent tanning lamp having a glass envelope has an ultra-violet light reflecting coating covering at least 180° of an inside surface of the envelope; and a phosphor layer covering substantially 360° of the inside surface of the envelope, including overlying the ultra-violet reflecting coating. An odor reducing photocatalytic material is provided on an outside surface of the envelope, the photocatalytic material being coextensive with the ultra-violet light reflecting material. A preferred material is anatase TiO2; i.e., the crystalline form.
