Sylvania 21767 FO32/841XP/ECO

The Sylvania 21767 FO32/841XP/ECO is a commercial-grade Octron® 800XP® Ecologic® 32W 4-foot T8 linear fluorescent lamp engineered for high-density office, healthcare, educational, and retail troffer applications. Delivering 3,000 initial lumens of 4100K cool white light at 85 CRI with 95% lumen maintenance, this premium tube achieves up to 44,000 hours of rated service life on programmed-start electronic ballasts — with a TCLP-compliant 3.5mg ultra-low mercury fill and G13 medium bi-pin base for direct drop-in compatibility with standard 48-inch T8 fixture platforms.

ADL Supply Expert Application & Replacement Guide

The Sylvania FO32/841XP/ECO is a commercial facility standard specified for corporate office troffers, healthcare corridor fixtures, institutional classroom grids, and high-density retail ceiling systems where 95% lumen maintenance over an extended service life significantly reduces relamping labor costs compared to standard T8 lamps. This lamp is compatible with both instant-start and programmed-start electronic ballasts — but the lampholder type must match the ballast type: instant-start ballasts require un-shunted (non-shunted) bi-pin lampholders, where the two contacts within each socket are electrically isolated from each other, allowing the high open-circuit ignition voltage to strike the arc correctly. Programmed-start ballasts require shunted bi-pin lampholders, where both contacts are internally connected to deliver simultaneous preheat current to both cathode filaments before ignition. Installing mismatched lampholders — shunted sockets on an instant-start ballast, or un-shunted sockets on a programmed-start ballast — will result in lamp non-ignition or premature lamp failure. The rated life varies significantly by ballast type and switching cycle — programmed-start on 12-hour continuous cycles achieves the maximum 44,000-hour rating; confirm which life rating applies to your installation conditions in the spec list below.

Operation, Safety & Mounting Compliance

Lampholder Type Selection — Critical Installation Requirement

The lampholder type must be matched to the ballast starting method — this is the most common installation error in T8 fluorescent retrofits. Instant-start ballasts apply high open-circuit voltage directly across the lamp pins without preheating, requiring un-shunted lampholders where both pin contacts within the socket are electrically isolated. Programmed-start ballasts preheat the cathodes before arc ignition, requiring shunted lampholders where both contacts are internally connected to deliver simultaneous preheat current to both filament pins. Installing the wrong lampholder type for the ballast in use causes lamp non-ignition on instant-start circuits with shunted sockets, or bypasses cathode preheating on programmed-start circuits with un-shunted sockets — both result in premature lamp failure.

Ecologic® Mercury Content, TCLP Compliance & Disposal

The Ecologic® low-mercury formulation limits the internal mercury fill to 3.5 mg, allowing spent lamps to pass the Federal TCLP (Toxicity Characteristic Leaching Procedure) test protocol under NEMA guidelines — qualifying for non-hazardous waste treatment in applicable jurisdictions. Despite this certification, lamp recycling through a certified e-waste program remains required by federal and state regulations and is best practice for all mercury-containing fluorescent lamps. This product cannot be shipped to CA, CO, HI, ME, MN, OR, RI, or VT due to state-level mercury lamp regulations.
