MR16 Halogen or LED? Pros and Cons?

Is the switch itself specifically for dimmer led bulbs. I don't think you can use ordinary dimmer switches for LED lights.

I have an issue with my dimmer and now I know why. I did suspect the switch but did not realise there are dimmable led switches and two types!
