    Hi all

    I bought these lights from B&Q

    https://www.diy.com/departments/carmenta-brushed-chrome-effect-6-lamp-ceiling-light/1700097_BQ.prd

    they sell these lights with it:

    But I bought these instead as I wanted cool white:

    WOWLED G9 LED Light Bulb, 3W (30W... https://www.amazon.co.uk/dp/B07HG3JH5Q?ref=ppx_pop_mob_ap_share

    why don’t they fit in though? They are also G9?? But the bottom is different for some reason

    The difference in shape is due to the need for a driver to control the current that flows through the LED elements.

    There has to be space for the components of the driver and a heat sink to disipate the heat produced in the driver.

    I thought it was the leads/connection point that was the problem?

    Yes it’s the connection point that’s stoping the LED ones going in

    the light manufacturer really ought to make clear it’s only g9 halogen that’ll fit

    I believe led are also more efficient?
    Plus they are cool white which is my preference

    just strange they are not standard in this day and age!

    Your not the only one to be caught out with G9 bulbs, the quartz bulbs can shatter so quartz bulbs not only G9 need to be in glass so if they shatter hot bits can't set your carpet on fire, this is not required with LED, so some G9 lamps are designed for LED only, for a dimming switch to work, or any other electronic switch, where there is no neutral to the switch, a small amount of current needs to pass through the bulb without the bulb lighting, bulbs without this are marked non dimmable. However the G9 is so small there is not the room for the leak through resistor or capacitor so it has to be added to the fitting, a 4 uf capacitor is not that small and getting it to fit inside the fitting is a squeeze. Then even after fitting dimmable bulbs, and the capacitor the bulbs still from time to time pulse.

    So my lights do have covers over the bulb, but the heat from a quartz lamp is quite a lot, and it was bought fitted with LED bulbs, so not sure what size if any quartz bulbs can be fitted?

    GU10, E14, BA22d, all no problem even with non dimmerable bulbs using electronic switches, just G9, and only one lamp with G9, if I had a few lamps could try swapping bulbs, but if I buy 5 new bulbs and they don't work, then I have 5 bulbs to put in the bin.

    I hate G9 lamps.

    Surely you have 5 bulbs to take back, not put in the bin.
