Dear Marge, my friend needs help with a personal and intimate matter. He was looking at two old recessed ceiling luminaires recently that used to take a large compact fluorescent lamp with a GU10 lampholder. The old lamp was a spirally glass tube thingy. Anyway, the householder had bought new GU10 L.E.D. lamps with a long neck which looked as though they might fit. The thing was the new lamps could not be rotated in the lamp holders. The pins would locate but the lamps could not be rotated. Can you advise my friend as he is getting very frustrated.
Z.
