So the problem/question is: if i drive an incandescent lamp all goes perfect, if i fire a solenoid, all goes perfect, if i run an AC motor, all goes perfect, BUT if i try to light one of those new led lamps or a saving energy lamp (kinda flourecent lamp) then the lamp goes dimmed when it should be off and full light when on, even the fluorecent one starts to flashing (some models) in the off cycle......
Have you any ideas about this behavior or how to avoid it?
Hi;
I think this is caused by the R3-C1, the LED or the saving energy lamp is still working in a 'dimmed mode' (with a low current via R3-C1) also without the triac, try it.
Do not use R3-C1 but increase the value of the R2 (from 180 Ohm to 470 Ohm, for example).

Sorry for my mistake: R3-C1 (of course)
