Every two weeks for the last 2 years, a 12 volt incandescent lamp burns out.  Voltage at lamp is 10.8 VAC typically.  We called the fixture manufacturer and they said it was a transformer issue.  How can we eliminate lamp failure?

Six MR16, 50watt, 12volt lamps on each cable/track. I have to reset using the rocker switch (low voltage circuit breaker on the Semper Fi transformer). One track trips after about 10 to 15 minutes. The other one trips after track been on for a day. Electrician was thinking the dust build up on the track could be causing the problem.

I've attached a cut sheet for the fixture in question and the cut sheet of the LED lamp that will be used in it.  We need a transformer that will dim to 1%.  What is the best method?
