ADL Supply Expert Application & Replacement Guide
The Sylvania FO32/735/ECO (Item 21998) is a commercial facility standard for corporate office troffers, healthcare corridor fixtures, institutional classroom grids, and retail ceiling systems where 3500K natural white is the specified color temperature and TCLP-compliant low-mercury construction is required. The Octron 700 series delivers CRI 78 — adequate for general commercial illumination but below the CRI 82–85 of the Octron 800 series; confirm CRI requirements for your application before ordering, particularly for color-critical retail or display environments. This lamp is compatible with both instant-start and programmed-start electronic ballasts — but the lampholder type must match the ballast: instant-start ballasts require un-shunted (non-shunted) bi-pin lampholders; programmed-start ballasts require shunted bi-pin lampholders. Confirm your fixture's existing lampholder type before ordering when retrofitting, particularly when changing ballast start methods during an upgrade. For partial relamping, confirm all existing lamps are 3500K before ordering to avoid a perceptible color inconsistency.

Verify Before Ordering
Match Lampholder to Ballast Type — Instant Start Needs Un-Shunted | Programmed Start Needs Shunted | State Shipping Restrictions Apply
Instant-start ballasts require un-shunted bi-pin lampholders. Programmed-start ballasts require shunted bi-pin lampholders. Confirm your fixture's lampholder type before ordering for retrofit applications. Verify ballast is rated for 32W T8 electronic operation. Confirm 3500K natural white matches your existing installation color temperature before partial relamping.

Operation, Safety & Mounting Compliance
Lampholder Type, Ballast Compatibility & Octron 700 vs 800 Series
As with all 4-foot T8 linear fluorescent lamps, the lampholder type must match the ballast starting method. Instant-start ballasts require un-shunted lampholders where both pin contacts within each socket are electrically isolated. Programmed-start ballasts require shunted lampholders where both contacts are internally connected. Installing the wrong lampholder type for the ballast causes non-ignition or premature lamp failure. The Octron 700 series provides CRI 78 — adequate for general commercial task and ambient lighting. For applications requiring higher color fidelity, the Sylvania Octron 800 series (FO32/835/ECO or FO32/841/ECO) provides CRI 82–85 at the same wattage and form factor.
