Hi Pete,

What application do you use to dim/bri-it?

Another question... someone have tried to change the included triac
BTA10-400C (10A/400V) with a BT139/800 (12A/800) one in order to increase
the maximum power? I need to operate a set of 15x50W halogen spots (750W).

This modification is enough or more changes in the schematic are necessary?

Thank you,
Dan

  I think it's rated at 40w minimum. I've got one driving 3x15w and it works
  fine.

  Hi,

  How much do you load it?
  I hear that it is not reliable at low power loads (<60W).

    Dan,

    LM can be brightened and dimmed.

    I've never had problems with mine :-(

    Hi all,

    How a LM12 lamp module must work?

    Is it able to dim and bright, or only to dim?
    I have a new one and it is almost impossible to use it.
    Loaded with an 100W lamp it can be ON/OFF using X10 commands, but when
  dim,
    sometimes it try to dim a little bit then start to flash and it can not
be
    powered off by X10 commands anymore. It must be disconnected from the
  mains
    in order to stop it.

    Another question: It is possible to have local dim/bright commands for
  LM12
    module, by modifying it?

    Anyone can help?

    Thank you,
    Dan
