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 Luminaires manufacturers. The new ANSI G6.6 T-LED fits system is intended to be used within luminaires traditionally designed for linear fluorescent lamp systems.

Please see below ANSI C81.61, “Electric Lamp Bases” and ANSI C81.62, “Electric Lampholders”G6.6 figures and dimensions requirement:

Lampholder Manufacturers

Updated its certification guidelines to allow for a  Listed 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

Updated its certification guidelines to allow for a Listed 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 . 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 Luminaires Retrofit Kits (IFAR), and will be evaluated to UL 1598C & CSA TIL No. B-79A, the Standard for Light-Emitting Diode (LED) Retrofit Luminaires Conversion Kits.

Luminaires 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.

BACL technical experts recommend:

Traditional LED Type B tube only can certified as Retrofit Kit (UL1598C+UL1993, Classified certification) for export to North America market, but now add a certification program, you can use G6.6 ANSI standard lamp base directly as a whole new type LED light source (UL1993, Listed certification) Sales in North America! First of all greatly reduce the cost of certification and shorten the lead-time, and secondly, no longer need Qualified Electrician Renovation, the use of more convenient and reliable!
