    We have a 20 year old leading edge system which, as you all know, struggles with LED lights. I have 2 questions.

    1/ Does anyone know of any ceiling lights that are compatible with this system. Looking around 30cm.

    2/ I recently changed the old exterior GU10 downlights to new led GU10s and still struck the same problem of them staying on. I bought a 31LCDA and put it in series with one of the lights but it failed to make any difference at all. Lights still glowed.

    Any thoughts on any or both of these?

    Hi,

    Did you read the instructions on the 31LCDA?

    LCDA should be wired in parallel typically works better closer to the load.

    This is what happens in series.

    Haneco Dular and Viva 110 are compatible with leading edge dimmers but you need at least 2 of them on a group.
    I find that LCD's cause more issues than they fix.
