I actually need one of these because one of the recessed halogen lights in my apt stopped working.
At first it was flickering, at random times (along with the other lights) and then went out totally.
The only reasons I can think of that may have caused the flickering (which hasn't happened since) are
1) Maybe there is something wrong with the dimmer (this room is on a 3 way circuit with 1 dimmer)
2) Maybe it has something to do with the Ethernet over powerline running through the apartment.
When I removed the housing and changed the bulb it didn't seem to make a difference, so I'm thinking I need to check the power with a multimeter.
Also in the bedroom it seems as if one of the halogen recessed lights is much dimmer than the others causing uneven room light. I wonder if that is the next to go...
