Upc 008938 790901 3 halogen light fixture

Not 100% sure but I suspect the LED replacements exhibit a significantly higher impedance when off, unlike incandescent and halogen.

If you have multiple cans controlled by one switch, try changing all but one to LED and likely there will be no flicker at the lighted switch.

If you leave at least one halogen on the circuit and it still flickers, be sure to comment here and I'll research further.

Replacement style led's lamps are available for nearly any fixture. Take one of the halogens to your local box store and ask for a replacement led.

All light fixtures should be grounded IF they have a metal casing. If they are plastic caring there is no need for a ground. I doubt a halogen has a plastic case, they get much too hot

Please see my answer at http://www.fixya.com/support/t9977585-sv168n_36_spagna. I suspect your problem is with a failed transformer, rather than the actual halogen fixtures.

if fixture is as shown, remove the nut in the middle of the fixture, remove the lamp, and replace it, note donot touch the lamp with your fingers, this causes lamp to fail, use a cloth to install then replace in reverse as you took it apart

I am going to stick my neck out a little with this one although I agree with BoomerP. The clue of halogen bulbs is feeding my answer. Halogen bulbs require a high voltage transformer to operate and won't normally work with a dimmer but I never tried it. Bypassing the switch should bring them on though. If you have the proper voltage at the switch and they don't work with the switch bypassed, its probably a bad transformer in the fixture. Good Luck. Be careful.

To remove it use a paper towel or wear clean gloves the oil from your skin will cause it to blow, Grab hold of it from the middle and gently push left or right. Be sure power is off.

This dimmer was not made to dim a load smaller than 40VA. That halogen bulb would only have been 20VA or so.

I think that when your bulb burnt out, the dimmer over-volted the transformer and smoked it. That said, I think you have a fixture problem and, possibly, a switch problem, too.

check the kit at home depot, get name and phone number of manufacturer and call them to see if they can supply the glass that you want.
