tim west said:A bit of preheat will get round this, you could wind up the dimmer just a bit before going to full on
it's also good practice with GLS incandescent lamps as you don't want to stress the filament turning full on straight away.
Sorry to disagree but that is not the case, The way a triac based dimmer works is that it in effect changes the power characteristic of the load ie it chops the sine waveform at a particular timing in the cycle,bernardgreen said:But the triac is still having to switch the cold to warm filament current 100 times a second so if the triac is un-able to carry that much current it will still fail.
