UL Announces Certification Options for New ANSI T-LED Fit System

February 13, 2017

UL is excited to announce new certification options designed around the newly approved ANSI G6.6 T-LED fit system! On February 10, 2017 NEMA published revisions to ANSI C81.61, "Electric Lamp Bases” and ANSI C81.62, "Electric Lampholders”. These revisions include a new fit designed specifically for T-LEDs. This new T-LED fit system will allow for new certification options for Lampholder, T-LED, Retrofit-kit and Luminaire manufacturers. The new ANSI G6.6 T-LED fits system is intended to be used within luminaires traditionally designed for linear fluorescent lamp systems.

Lampholder Manufacturers

UL has updated its certification guidelines to allow for a UL Listing of ANSI G6.6 lampholders under the category for Solid-state Lighting Bases, Holders and Connectors (OLFB). These lampholders will be evaluated to UL 8754 (CAN/ULC-S8754), the Bi-National Standard for Holders, Bases, and Connectors for Solid-State (LED) Light Engines and Arrays.

T-LED Manufacturers

UL has updated its certification guidelines to allow for a UL Listing of line connected T-LEDs utilizing the ANSI G6.6 T-LED fit system. These certifications will be placed under the category Lamps, Self-ballasted, Light-emitting-diode Type (OOLV). These T-LEDs will be evaluated to UL 1993 (CSA C22.2 No. 1993-12 & NMX-J-578/1-ANCE), the Tri-National Standard for Self-Ballasted Lamps and Lamp Adapters.

Retrofit-kit Manufacturers

New certification options are available for Retrofit-kit manufacturers who are looking to leverage the new ANSI G6.6 T-LED fit system. Retrofit-kits are classified under the category Light-emitting-diode Luminaire Retrofit Kits (IFAR), and will be evaluated to UL 1598C & CSA TIL No. B-79A, the Standard for Light-Emitting Diode (LED) Retrofit Luminaire Conversion Kits.

Luminaire Manufacturers

We are excited to announce new general coverage options for both Surface Mount and Recessed LED Luminaires (IFAM and IFAO) that leverage the new ANSI G6.6 T-LED fit system based on requirements in UL 1598 (CSA C22.2 No. 250.0-08 & NMX-J-307/1-ANCE), the Tri-National Standard for Luminaires.
