    What is a non-dimmable light? 4th Dec 17 at 4:03 PM
    We bought two lights from B&Q that use G9 bulbs:

    http://www.diy.com/departments/mantus-chrome-effect-5-lamp-ceiling-light/1702673_BQ.prd?icamp=recs&rrec=true

    We then put 5 9W bulbs in each, which gave us an incredibly bright room.

    Our solution was to fit a dimmer:

    To my untrained eye this seemed to be the correct match for us and the W load was within range.

    However when we fitted the switch, the metal plate got so hot that it was impossible to touch. Also the "on/off" switch did not work consistently.

    My first instinct is a broken switch, but we then noticed on the light itself it says non-dimmable; the bulbs however are.

    I had no idea there was such a thing as a non-dimmable light, instead thinking it just distributed the power sent to it by the switch.

    So before I spend more money on another switch, is it possible that a light fitting can be "non-dimmable"?
    The above facts belong to everybody; the opinions belong to me; the distinction is yours to draw...

    Yes, to have dimmable light, both the light bulbs, switch and light fitting all need to be dimmable.

    LED bulbs won't be dimmable unless explicitly stated; just swap them for dimmable models. The light fitting is unlikely to contain more than a connector block to split the power, so that shouldn't be an issue.

    That dimmer you link to is for LEDs only but I think you have halogen bulbs.
