Product Overview

The Sylvania 51833 QTP2X26CFUNV-DM is a versatile professional-grade CFL ballast supporting one of the broadest lamp compatibility ranges in the Quicktronic line — covering PL-C, PL-T, PL-L, Dulux L, Dulux F, CFL Square, and T5 circular lamp types across multiple wattages. This single ballast can replace five discontinued Sylvania models (51793, 51733, 51763, 51738, 51768), consolidating ballast inventory for facility maintenance and multi-lamp applications.

Programmed rapid start preheats lamp cathodes before striking the arc, protecting filaments and extending lamp life — particularly important in high-switching environments or occupancy-sensor-controlled fixtures. Remote mounting capability up to 15 feet (1 lamp) or 6 feet (2 lamps) supports architectural applications where the ballast must be located away from the lamp. Dual-entry connectors allow side or bottom exit lead configuration to fit a variety of fixture designs. UL Type 1 Outdoor rating extends installation flexibility to covered outdoor applications.

Note: This is a ballast only — mounting plate, wire, and tools not included. The complete kit version is available as Sylvania 51852 QTP 2x26CF/UNV-KIT.
