Dimmable LEDs

    I want to fit a dimmable bulb to an aglepoise style lamp mounted on a high shelf.
    I plan to use a 13w dimmable LED bulb.
    I need to be able to have a really bright light for detailed work but then turn it down when using a computer etc.

    Would this work with a normal dimmer switch ?
    Would a 13w LED generate much heat to the bulb holder ?

    Thanks

    I am confused. The dimmers says suitable for LED & the bulb says dimmable.

    Am I better off just using a old fashioned high energy bulb ?

    LED light bulbs. Dimmable LED light bulbs can be dimmed with a normal resistive dimmer. They consume very low wattages and are extremely energy efficient.

    Then it should work (assuming it is rated for 13W or more).

    The dimmer minimum power is usually the issue, the ones that are not suitable for LEDs will not work properly with loads lower than 40W
    The dimmer is not resistive, it's still a triac based dimmer but designed for LEDs.
    I had some issues with dimmable LEDs even when using them with LED dimmers, they didn't go full power and there was some buzzing and there was that 50Hz flicker that you don't really see but you notice when looking at moving/spinning objects.
    So it may work flawlessly, or there may be some issues, you won't know until you try.

    Best off getting one of the smart ones that you can control brightness and colour/warmth.

    Yes but the ones I have seen don't go that bright. I am trying to make one light do two jobs

    Maybe 2 lights will work better? A dim soft warm one for working at the computer and a bright colder one for fine work?

    I swapped out our "standard dimmers" for one suitable for dimmable LEDs, went with the Varilight V-pros:

    Got them quite cheap from: https://www.tlc-direct.co.uk/
