Product Overview

The GE 75381 GE332MVPS-N-V03 is a 2-3 lamp version of GE's UltraStart normal BF 0-10V dimming T8 ballast series. This ballast provides the same full 100% to 3% 0-10V dimming capability as the 4-lamp GE 75382 (GE432-MVPS-N-V03) in a smaller form factor suited for 2-3 lamp T8 fixtures. Normal ballast factor (0.88) delivers full rated lamp lumens without over-driving.

Universal voltage operation (120–277V) covers all standard North American commercial circuits. Programmed rapid start preheats cathodes before ignition, extending lamp life in the variable duty cycles typical of dimming installations. Parallel lamp circuit keeps remaining lamps operating if one fails.

Compatible Lamps

(2–3) F32T8 — standard 48" T8
(2–3) F32T8/WM — energy-saving 48" T8
(2–3) F28T8 — 28W T8
(2–3) F25T8 — 36" T8
(2–3) F17T8 — 24" T8

Compatible Applications

0-10V dimming commercial lighting — Daylight harvesting and automated dimming control in 2-3 lamp T8 fixture configurations.
Normal output dimming systems — Full rated lamp lumens at 0.88 BF with continuous 0-10V dimming capability.
Universal voltage commercial systems — Single SKU covers both 120V and 277V commercial circuits.

Before Ordering — Verify

Dimming Protocol: Requires a 0-10V analog dimming controller — not compatible with DALI, phase-cut, or switching-based bi-level controls.
Lamp Count: Confirm fixture requires 2 or 3 lamps. For 3-4 lamp configurations, see GE 75382 (normal BF) or GE 75385 (high BF).
Lamp Type: Confirm lamps are on the compatible list above.
Input Voltage: Confirm circuit is within 120–277V ±10%.
Physical Fit: Confirm 9.5" x 1.7" x 1.18" fits within your fixture's ballast cavity.
Socket Type: Programmed start requires un-shunted lampholders — verify before installing.

Safety and Installation Guidelines

Disconnect and lock out power before removing or installing a ballast.
Ground the ballast and fixture properly per NEC and local electrical codes.
Do not bundle lamp leads — excess wiring can cause starting or performance issues.
Qualified personnel only — install per applicable electrical codes.
