We have had the Altman Phoenix for over a year now. Trying to use the 750 lamps, HPL with the 115 X. They over heat and blow way to soon. We are not running voltage over 117 so that should not be the problem. Altman says we are the only house with this issue. I don't believe them. We did not have any of this with our previous instruments. Anyone else having this type of issue?
