SYLVANIA DULUX T/E/IN, T/E/IN/SS, T/E/IN/XL, and T/E/IN/ XL/SS compact fluorescent lamps are ideal for use in a wide range of commercial and residential applications. They are desinged to be operated on energy efficient electronic and dimming ballasts. All lamps in this family contain amalgam technology which provides higher lumens over a much wider temperature range than non-amalgam lamps. SUPERSAVER compact fluorescent lamps are energy saving replacements for full wattage triple tube cfl lamps. No ballast change is required to reduce energy costs by up to 19%. EXtended Life Lamps are direct replacements for standard life DULUX T/E/IN lamps and provide up to 67% longer life.  Additionally, the EXtended Life SUPERSAVER versions have long life, the energy savings, and improved lumen output of 6% of the standard life SUPERSAVER lamps. For all lamps, the triple tube configuration of these lamps allows for single-lamp luminaire designs with improved efficacy and photometric performance.
