Product Overview

The Sylvania 50736 QHE2x32T8/UNV/DIM/TC is a high-efficiency QUICKTRONIC® T8 electronic dimming ballast designed for two 32W T8 fluorescent lamps. It supports universal 120-277V input and 50/60Hz operation, making it suitable for a wide range of commercial lighting systems.

This ballast uses PROStart programmed rapid start technology and QUICKSENSE® end-of-lamp-life sensing to support reliable operation in properly matched fluorescent fixtures. Its 1-10V dimming capability allows integration with compatible lighting controls where adjustable light output is required.

The low-profile 9.5-inch by 1.68-inch by 1-inch housing is designed for fixture installations where compact ballast dimensions are important. The ballast is intended for professional electrical installation and should be matched carefully to the fixture, lamp type, and control system.

Compatible Applications

Commercial 2-lamp T8 fluorescent fixtures
Office lighting systems using 32W T8 lamps
Schools, hospitals, retail, and institutional facilities
Lighting retrofit projects requiring universal voltage electronic dimming ballasts
Fixtures requiring 1-10V dimming control compatibility
