Product Overview

SYLVANIA 49136 | QTP2x54T5HOUNV PSN Quicktronic® 2-Lamp 54W T5HO Ballast

The Sylvania 49136 (QTP2x54T5HOUNV PSN) is a commercial-grade, high-performance **electronic fluorescent ballast** designed to operate one or two 54W T5HO lamps. Operating on a universal voltage range of **120-277V**, this Quicktronic® Professional series ballast features advanced **ProStart® programmed rapid start technology**, which precisely heats lamp filaments before ignition to significantly extend lamp life and maximize switching cycles. Engineered to withstand the harshest commercial and industrial environments, it features a heavy-duty **90°C high-ambient thermal case rating** and reliable cold-weather starting down to **-20°F**, making it an ideal choice for high-bay fixtures, warehouses, and outdoor enclosed environments.

ProStart® Technology for Demanding Applications

Standard instant-start ballasts can induce severe electrical stress on tube cathodes during system ignition, leading to premature lamp blackening and filament failure. Sylvania's **ProStart programmed rapid start** system solves this by delivering a brief, tightly controlled preheating cycle prior to applying the strike voltage. This structural ignition management makes the **49136 ballast** exceptionally optimized for use alongside occupancy sensors, building automation systems, and high-cycling workspace layouts where lights are routinely toggled throughout the day.

High-Frequency Mitigation: Operates at an ultra-quiet internal frequency above 40 kHz, successfully eliminating lines of infrared interference with nearby remote control or sensor hardware.
Extreme Durability: Incorporates a full UL Type CC rating (anti-arcing protection) and a UL Type 1 Outdoor classification for stable integration inside damp or weather-exposed structural channels.
Eco-Minded Engineering: Manufactured using entirely lead-free processes to ensure strict compliance with international RoHS hazardous waste guidelines.
Simplified Inventory: The auto-sensing voltage circuitry automatically configures itself to cleanly handle any electrical line input ranging from standard 120V up to 277V.
