Sylvania 20318 CF13DS/E/841

The Sylvania 20318 CF13DS/E/841/ECO Dulux S/E is a high-efficiency 13W single-tube compact fluorescent lamp engineered for electronic and dimming ballast applications in commercial task lighting, recessed downlights, wall sconces, and specialty display fixtures. Delivering 800 initial lumens of 4100K cool white output at 82 CRI through a 2G7 4-pin base, this Ecologic® TCLP-compliant lamp provides a 10,000-hour rated service life with flicker-free electronic ballast starting and optional dimming capability.

ADL Supply Expert Application & Replacement Guide

The Sylvania CF13DS/E/841/ECO (Order Code 20318) is primarily specified by electrical contractors and facility maintenance teams for commercial task lighting, modular recessed downlights, wall sconces, exit sign illumination, and display showcase fixtures where the compact Dulux S/E single-tube format and 4100K cool white are the installed standard. The 4-pin 2G7 base is the electronic ballast version of this lamp family — the 4-pin configuration lacks the integrated starter found in 2-pin Dulux S lamps and requires an external electronic ballast to provide cathode preheating and arc ignition. The 4-pin lamp will not operate on magnetic ballasts designed for 2-pin single-pin-start lamps. Programmed-start electronic ballasts for this base require shunted lampholders where both socket contacts are internally connected. This lamp is compatible with dimming electronic ballasts when dimming capability is specified — confirm the installed ballast carries a dimming rating before specifying this lamp for dimming applications. The 10,000-hour rated life is based on 3-hour burn cycles; continuous-burn or longer-cycle applications will extend actual lamp life beyond the rated figure.

Operation, Safety & Mounting Compliance

4-Pin Electronic Ballast Requirement, Shunted Socket & End-of-Life Shutdown

The 4-pin 2G7 base is the programmed-start electronic ballast interface for this lamp family — the four pins provide separate connections for each cathode filament, allowing the electronic ballast to preheat both filaments before ignition for flicker-free starting and extended cathode life. Shunted lampholders, where both contacts in each socket are internally connected, are required for this lamp's base configuration. The lamp will not ignite on magnetic ballasts, and substituting a 2-pin magnetic-start ballast will result in non-ignition. Per NEMA standards for high-frequency electronic ballast applications, a shutdown (end-of-life detection) circuit is recommended to prevent repeated re-ignition attempts on a failed lamp that could stress the ballast's output stage.

Ecologic® Mercury Content & Disposal

This lamp's Ecologic® construction is TCLP compliant, qualifying spent lamps for non-hazardous waste treatment in applicable jurisdictions and reducing bulk disposal costs for large institutional relamping programs. Despite TCLP status, lamp recycling through a certified program remains required in most states. This product cannot be shipped to CA, CO, HI, ME, MN, OR, RI, or VT.
