Help Needed GU10 Lampholder.

Zoomup

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.

    Dear "friend"

    The chap at the clinic suggests that Gu10 lamps and their  holders

    (to be sure, we mean one of these)

     

    agree on the pin diameters and spacing , but are sometimes a bit variable on how tall the metal 'mushroom heads' stand above the reference plane.

    If the fatter part at the top of the pin is not going fully in then the lamp will be unable to tuirn and engage.

    It is also possible the existing holders have been slightly distorted by  heat from the previous lamps

    You could do worse than try the offending lamps in a spare lamp holder outside the fitting to compare the looseness of fit compared to the lamps that do work.

    It is also possible the existing holders have been slightly distorted by  heat from the previous lamps

    It might be possible to 'trim' the plastic on the lamps slightly if the error is slight, but this should be a last resort.

    Mike, as Marge is unwell.

    I think you'll find she's a bit more than "unwell" Mike!
