@MarfyMazie@yiff.life @Beckydog@hydaelyn.coerthansnowstorm.online For the light: 546 is old, but still valid - 1363 itself is over 80 now, being first introduced in the late 40s. 546 has multiple plug/socket types, the most common being 3 and 5 below the (massive!) 15A. A modern light (led) isn't going to get anywhere near the capacity of a 3A, let alone a 5A 546 plug. Using it: If you don't want to mod the lights, I'd get the right plug and a single socket extension and use it to make a (short) converter from 546 to 1363, and mark it very clearly for lights only.
