    Have 2 wall mounted wall lights.
    The bulbs dim with a knob on the light fitting.
    Changed bulb to dimmable LED.
    Now the LED bulb won't switch off fully.
    There's a small glow off the bulb.
    Don't really want to change the fittings if possible

    Does the bulb continue to glow when you remove it from the fitting or does it go out straight away?

    Can't say that I ever took notice !
    Went back to the standard bulbs.
    Must try again !

    Did you just replace the bulbs to LED? You will need a LED dimmer switch too

    The dimmer you have is still providing some voltage rather than going off entirely - but it'll likely also kill the bulbs soon enough if its a bog standard dimmer from the old days. Dimmable LED does not mean it works with old fashioned rheostatic dimmers.

    The dimmer switch is a knob on the light fitting.
    At the moment I don't want to replace the 2 fittings.

    I once came across a product like this;

    https://hartingtonheath.com/product/i-lumos-led-adapter-for-use-against-dimmer-light-switches-flickering/

    It's a resistor and is meant to stop flashing or flickering.

    It probably will sort it, as would a normal incandescent in parallel with them. Although that would be less practical.

    If you put the old on off light switch back and the issue goes then the issue is your dimming switch not being able to dim low enough for the low energy lamps.

    The correct dimmer, or one of the ones that has the on off feature even you press the dimmer knob button are options.

    FTR, LED GU10's in my house have an afterglow that lasts a few minutes on a straight up on off switch.

    Phillips master range, not cheap Lidl / Aldi ones.

    Electroboom has a video on the topic. Ignore his (faux) safety nightmares. Doesnt have to be the dimmer, it can be very small amounts of induced current. Only certain models of LED lights will illuminate at such levels.
