    Hi

    Can anyone suggest replacement LED light globes to suit MR16, 50 watt.
    I have tried numerous ones but the LED brands but they don't dim very well.

    Any comments would be appreciated.

    Thanks

    I assume you are using these on universal dimmers, not leading edge ones?

    They seem to work happily on both dimmers, at least with the drivers that came with them which say they are happy with current clamp dimming.

    Rab, you will need to ensure that the built-in driver is dimmable, its not as simple as just swapping the globe out in most cases.

    The issue you will run into is MR16 is a very small formfactor with no way to easily cool them so you will be limited to low wattages of 5-7

    Philips "Master" comes in MR16 and are dimmable but only in the 7w that I know of.

    To run LEDs you need a driver circuit which controls the power supplied to the emitter array.

    These drivers usually operate as a PWM output circuit and an AC->DC rectifier. The circuits inside have to be designed to be dimmed to work with a dimmer. Otherwise u will shorten their lives assuming they work at all while dimmed.
