Product Overview

The Sylvania 20318 is designed for fixtures where space is limited but high-quality light is essential. As an "S/E" (Single-Ended) lamp, it lacks the integrated starter found in 2-pin versions, allowing it to interface directly with external electronic ballasts for better energy efficiency and dimming capabilities. The 4100K color temperature provides a clean, neutral white light that improves focus and visibility in professional environments. Its Ecologic construction ensures it passes the TCLP test for non-hazardous waste, making it an environmentally responsible choice for large-scale facilities.

Applications

Commercial & Office: Task lighting, recessed downlights, and modular ceiling fixtures.
Specialty Lighting: Wall sconces, exit signs, and display showcases.
Outdoor: Enclosed fixtures for security and accent lighting (ballast dependent).

Ballast & Safety Notes

⚠️ Ballast Requirement:

This is a 4-pin lamp and must be used with a compatible electronic ballast. It will not operate on magnetic ballasts designed for 2-pin lamps. Per NEMA standards, the use of a shutdown circuit is recommended for high-frequency ballast applications to prevent end-of-life issues.

Dimming: Compatible with dimming systems when paired with a dimming-rated electronic ballast.
Starting Temperature: Varies by ballast; typically rated for cold starts down to 0°F.
Life Maintenance: Ratings are based on 3-hour cycles; longer operational cycles will significantly extend the 10,000-hour life.
