Guide for specifying LED substitute light source categories as equivalents for corresponding filament light source categories prepared by the Task Force on Substitutes/Retrofits.

GRE and its Task Force on Substitutes and Retrofits proposed and GRE at its 79th session agreed to include an “interlock feature” for LED substitute light sources to prevent the misuse of these light sources. The first LED substitute category proposal is the “PY21W/LED”. A further solution has been developed by IEC cap-holder experts in IEC TC34/SC34B/WG2 by adding a “third pin” at an angle of 110° (from the reference pin) for the BA15 cap system, including the BAU15s cap prescribed for the PY21W filament light source category. This document contains the relevant cap and holder sheets for implementation in the IEC 60061 structure.
