    Intermittent MR16 downward lights

    Hi all. Just moved into a new home and I've got 4 of the kitchen downward lights that are out. Tried changing the filaments but it became obvious that the filaments are fine, it's the wiring into the back of the socket that's at fault. My question is how do you de-wire these MR16 GU5.3 sockets...

    MR16 LEDs - less video shimmer from dimmable lamps?

    Hi - I have a room lit by two undimmed strings of six x 4.5W MR16 no-brand non dim lamps. This system originally had 50W halogen MR16s and 2 x 300W torroidal transformers. Visually this was OK, but video flicker on a webcam was terrible with the LEDs (none in daylight or with a halogen lamp)...
