    Changing out old halogen dimmable downlights with transformers to new Martec LED dimmable with Dimming LED drivers ( constant current) 10w, tried one before getting to carried away.
    New LED work ok plugging into GPO but when installing into light point in ceiling which has a GPO the light works ok, dims ok but stays luminated slightly with a bit of a flicker when turned off
    Guessing the Cbus system may not like the driver or is it something else?
    Solutions?

    This is a common problem with many LED downlights. You will need a Load Bypass Device/Load Correction Device (LCD) to be installed across each dimmer channel where the problem occurs. This issue is due to 'off-state leakage' through the dimmer. The LCD will need to be installed by an electrically qualified person as this is deemed to be an alteration to fixed wiring.
