Product Overview
The Sylvania Quicktronic QHE 1x40DL/UNV Dimmable CFL Ballast is a high-performance electronic control gear module engineered to power a single 40W long compact fluorescent lamp. Featuring an auto-sensing universal voltage input range from 120V through 277V, this premium ballast provides a steady 1.00 normal ballast factor. Its dimmable design makes it an exceptional choice for commercial spaces integrating advanced lighting control networks, energy management systems, and ambient daylight harvesting zones.

ADL Supply Expert Application & Replacement Guide
The Sylvania QHE 1x40DL/UNV is widely specified for retrofitting and maintaining architectural recessed downlights, shallow surface-mount troffers, and commercial wall sconces using long 4-pin compact fluorescent sources. Meeting strict NEMA Premium Electronic Ballast criteria, it introduces deep power tuning capabilities to dimming fixtures, allowing facility managers to align their properties with modern ASHRAE and Title 24 building energy conservation codes.
Technical Wiring Note for Contractors: This single-lamp dimming ballast requires a continuous, clean low-voltage signal line connection to function under automated controls. Because it regulates current to a single long-twin-tube (DL) fluorescent lamp, technicians must verify that the fixture lampholders are shunted precisely according to the terminal schematics printed on the physical case housing. Ensure a rigid, solid mechanical ground connection exists between the small can steel frame and the luminaire chassis to prevent radio frequency interference or low-end dimming arc flickering on site.

Operation, Safety & Mounting Compliance
Electrical Connections & Code Compliance
This Quicktronic dimming module must be installed in strict compliance with the National Electrical Code (NEC) guidelines. Built with robust transient surge filters, it protects connected commercial circuitry from localized utility power spikes. It satisfies all FCC 47 CFR Part 18 Non-Consumer standards regarding electromagnetic radiation boundaries, ensuring no harmful feedback interferes with local IT server trays or medical equipment profiles.
Thermal Thresholds & Enclosure Protection
The maximum permitted metal housing case temperature is securely capped at 70°C (158°F). When installing within compact sheet-metal industrial luminaires, architectural troffers, or deep recessed downlight cans, verify that ambient ventilation lines are free of debris to avoid heat entrapment. The device is safety certified as UL Type 1 Outdoor Rated, making it robust enough to handle unconditioned storage environments or damp structural canopy soffits. It is constructed 100% RoHS certified and free of legacy hazardous PCBs.
