AC light dimming

Hi there! I'm currently working on this project, Dimming an AC bulb, can anyone help me with this one? please send me a working circuit of this if you have any. Thank you very much!

Dimming an AC bulb, can anyone help me with this one?

You need to say the wattage of the bulb before you can work out what solid state relay you need to use.

Maybe this old forum will help

Uh It's 50 watts ..

OK so you need one that handles at least 1A.
These are a bit over kill for what you want:-

Not sure where in the world you are but the magic words for google are:- scr phase angle

You should be able to find a local supplier.

Just out of curiousity, why wouldn't a TRIAC work?

It would, a triac is just two SCRs back to back in one package.
However most commercial systems use SCRs for splitting the heat dissipation between two devices. Others actually use triacs but have SCR in the description because it is a more popular name.

OR, if the thrill of the fun isn't in just figuring out how to do it, you can look into the X10 libraries and do some really cool stuff!
