Technical Specifications

Product Overview

The Sylvania 51408 QHE 2x32T8/UNV PSN-MC is an ultra-high-efficiency T8 ballast engineered for maximum energy savings and extended lamp life in commercial fluorescent systems. NEMA Premium rated at greater than 90% system efficiency, this ballast qualifies for utility energy efficiency rebates in many markets.

PROStart programmed rapid start preheats lamp cathodes before striking the arc, dramatically extending lamp life over instant start ballasts — particularly important in spaces with frequent switching. The ballast is rated for over 100,000 switching cycles, making it well suited for occupancy sensor-controlled fixtures. Parallel circuit operation means if one lamp fails, the other continues operating independently — unlike series-wired ballasts where both lamps go dark together.

Lamp Striation Control (LSC) technology prevents the visible gas spiraling or swirling that can occur with energy-saving T8 lamps. The -20°F cold start rating and compact Micro-Can housing (9.47" x 1.69" x 1.18") expand installation flexibility across a wide range of fixture types and environments.

Compatible Lamps

Compatible Applications

• Commercial T8 fluorescent fixtures — Office troffers, strip fixtures, wrap-around luminaires, and recessed lighting using 1–2 lamp T8 configurations.
• Occupancy sensor-controlled spaces — >100,000 switching cycle rating and PROStart protection make this ideal for high-switching applications.
• Low-temperature and outdoor applications — -20°F cold start for unheated spaces and covered outdoor installations.
• Utility rebate-eligible projects — NEMA Premium efficiency qualifies for energy efficiency incentive programs in many utility territories.
