It delivers 2600 initial lumens at 77 degrees F with a color temperature of 3500 K and a color rendering index of 85. The lamp uses rare earth phosphor technology and operates on both instant-start and programmed rapid-start ballasts, achieving rated lamp life up to 84000 hours under 12-hour programmed rapid-start cycling. Nominal length is 48 inches with a medium bi-pin base. Licensed electricians and lighting maintenance technicians handle installation in standard T8 fluorescent fixtures.\u003c\/p\u003e\n\u003cp\u003eThis lamp is suited for a wide range of commercial and institutional applications including education, healthcare, industrial, office, and retail environments. The reduced 28-watt wattage offers measurable energy savings compared to a standard 32-watt T8 lamp — up to 96 percent mean lumens retained over lamp life. Its Octron XP 800 series design supports high-frequency electronic ballasts. The lamp ships in a standard package of 30 units per case, making it practical for large-scale lighting retrofits and maintenance programs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e28-watt reduced wattage versus standard 32-watt T8 for energy savings\u003c\/li\u003e\n  \u003cli\u003eUp to 96 percent mean lumen maintenance over rated life\u003c\/li\u003e\n  \u003cli\u003eRated lamp life up to 84000 hours at 12-hour programmed rapid-start cycling\u003c\/li\u003e\n  \u003cli\u003eCompatible with instant-start and programmed rapid-start ballasts\u003c\/li\u003e\n  \u003cli\u003eRare earth phosphor construction for consistent color rendering\u003c\/li\u003e\n  \u003cli\u003eLead-free glass construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard T8 bi-pin fluorescent fixtures operating on instant-start or programmed rapid-start electronic ballasts.
