Hi,
for a triac dimmer you need a zero cross detection. Wit standard dimmer circuits this is managed by R, C and diac.
************
So you say it is blinking. Then you should have a circuit.
Show us your schematic. (I think this is the most used sentence here).
Without your schematic it is impossible to see where the blinking comes from.
Usually a dimmer can work without blinking.
************
For sure you can use other circuits for dimming lamps.
************
Is it alowed in your country to dim (with triac) that heavy loads?
If i remember right it is not alowed in germany´s public electric supply mains.
************
if this is not a single lamp, you can use multiple dimmers with lighter (allowed) load.
Just control one channel 0..100% then the other and so on until all are 100%.
