I'm renting a flat, and cannot change wiring within a room walls, and there is only single light switch, I'd like to be able to switch between 2 light bulbs depending of needs.
So when I turn light it would light up whole room high power LED and after off/on switching it would change in to directional bulb for my working desk.
I assume it would be 2 bit binary counter made with relays, but my rusty memory failed on me. Making it work with mains AC was main issue.
Might even use single relay, considering I only need one light source at the time. It would need latch relay after off/on action.
Idea was kinda inspired by these flip of a switch bulbs
