    Hello,

    Can you provide some details about the lamps and dimming circuit?
    Datasheets would be great.

    Greetings,

    A lot of ground was covered in this other thread.

    Use this thread to ask your question, this thread belongs to you alone. I'm referring you to the other thread as a reference.

    The other poster had a lot of Q&A sessions, he wasn't too happy with some of the answers.

    The short answer is it is unlikely you will be able to get satisfactory results using the built in dimmer. I could be wrong, but LEDs are not light bulbs. The way they light up when current is varied is very nonlinear. There is a technique called PWM that will vary a LED linearly, but it is totally different than the way typical dimmers work.

    I would assume the manufacturer matched everything else though, so the LED version should be a drop in replacement.

    Best advice is try it and see, if it doesn't work, then we'll be glad to work with you to make it right.
