Hi folks, We have a few rooms in the house with light fixtures that take MR16 light bulbs: https://www.amazon.com/Philips-Floo-...dp/B007RKVRVM/ In looking at the bulbs, it seems like these are halogen bulbs for 12V light fixtures. Some of these are hooked up to regular dimming light switches, so they must be dimmable, right? Does this mean I can use RRD-6CL switches with them? Or are there low voltage switches? Thanks!
