Built on the Octron 800 platform with rare earth phosphor technology, it delivers an initial output of 2,725 lumens and a mean output of 2,560 lumens at 25 degrees C. The lamp operates on both instant-start and programmed rapid-start ballasts, offering flexibility across a range of compatible fixtures. With a color temperature of 4100K and a color rendering index of 82, it produces a neutral cool-white light well suited to offices, retail spaces, and light industrial environments. Licensed electricians and lighting contractors handle routine installation and replacement.\u003c\/p\u003e\u003cp\u003eThis lamp is intended for use in U-bent fluorescent fixtures found in recessed troffers and other commercial overhead lighting systems. The 1-5\/8-inch leg spacing is the standard dimension for this lamp family. It is packaged individually and available in cases of 15. The lamp is TCLP compliant and lead-free, meeting environmental disposal requirements that are increasingly mandated in commercial renovation and new-construction projects. Rated lamp life ranges from 15,000 hours at 3-hour instant-start cycling up to 28,000 hours at 12-hour programmed rapid-start cycling, making operating cycle a meaningful factor in fixture selection.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e31-watt T8 U-bent form factor with 1-5\/8-inch leg spacing\u003c\/li\u003e\n\u003cli\u003e2,725 initial lumens and 2,560 mean lumens at 25 degrees C\u003c\/li\u003e\n\u003cli\u003e4100K color temperature with CRI of 82 for neutral cool-white output\u003c\/li\u003e\n\u003cli\u003eCompatible with instant-start and programmed rapid-start ballasts\u003c\/li\u003e\n\u003cli\u003eRated life up to 28,000 hours under 12-hour programmed rapid-start cycling\u003c\/li\u003e\n\u003cli\u003eTCLP compliant and lead-free construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for T8 U-bent fluorescent fixtures using medium bi-pin lamps with 1-5\/8-inch leg spacing and compatible with both instant-start and programmed rapid-start ballast systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and lamp replacement should be performed by a qualified electrician or lighting maintenance technician.
