Product Overview

The Sylvania Quicktronic 51472 QHE2X28T5UNVPSN is a high-efficiency T5 ballast engineered for full lumen output and optimal system performance with Sylvania PENTRON T5 lamps. PROStart programmed rapid start preheats cathodes before striking the arc, extending lamp life over instant start alternatives — particularly beneficial in applications with frequent switching. QUICKSENSE end-of-lamp-life detection shuts down the ballast circuit when a lamp fails, protecting the ballast and fixture from damage.

Operating output frequency greater than 40kHz reduces potential interference with infrared remote control systems — an important consideration in offices, conference rooms, and AV environments. The UL Type 1 Outdoor and 0°F cold start ratings make this ballast suitable for covered outdoor and low-temperature indoor applications. Universal voltage input (120–277V ±10%) simplifies specification across mixed-voltage facilities.

Compatible Lamps

(1–2) F14T5 / FP14T5
(1–2) F21T5 / FP21T5
(1–2) F28T5 / FP28T5
(1–2) F35T5 / FP35T5

Compatible Applications

Commercial T5 fluorescent fixtures — Office troffers, strip fixtures, and architectural lighting systems using 1–2 lamp T5 configurations.
Outdoor and low-temperature applications — UL Type 1 Outdoor rated; 0°F cold start for covered outdoor or unheated space installations.
AV and IR-sensitive environments — >40kHz output frequency reduces interference with infrared remote control systems.
Retrofit and maintenance replacement — Universal voltage input fits 120V and 277V commercial circuits without model changes.

Before Ordering — Verify

Lamp Type: Confirm your lamps are F14T5, F21T5, F28T5, or F35T5 (or FP equivalents).
Lamp Count: Confirm fixture requires 1 or 2 lamps.
Input Voltage: Confirm your circuit voltage is within 120–277V ±10%.
Physical Fit: Confirm 14.17" x 1.18" x 0.87" dimensions fit within your fixture's ballast cavity.
