Hi,
We've had some problems with the lamp contacts on our revolutions arcing. We have 4 revolutions and in the past couple of years I've had to replace the lamp contacts 3 times. I can't tell for sure whether the problem is in the contacts or the lamp itself. It seems that arcing is occurring and heating the contact on the lamp side enough that the metal from the lamp fuses with the contact and eventually develops a gap where the metal on the lamp contact bends and goes into the porcelain. We always make sure the lamp is seated fully and check that the springs are still applying pressure to the connections.
Is anyone else having this problem? Does it seem likely that we got a bad batch of lamps or is it more of a design problem?
Thanks,
Mat
