Triac Filtering Question

Hello All

I'm just finishing up a basic light control circuit using Triacs (2 CCTs On/Off and 1 Dimming)

My question is both the On/Off and Dimmable CCTs will be controlling basic incandescent bulbs upto a total of 600W ea CCT.
What is the ideal filtering and placement for EMI/RF etc. filtering and how would this be calculated for future projects.

In short would you put discrete inductors, capacitors resistors in CCT or buy one from, say RS, again how do you choose the appropriate device.

Thanks in advance

Anyone?????

I suggest you try and see what is used commercially, you will probably be surprised how crude it is.
