I have a medical device with a blown globe. I measured 240volts at the globe but the suppliers says it takes a 120V globe. I asked them if they are sure because I measured 240volts at the terminal. Their reply was that they run the 120V globe at 240V but at a lower amperage. They do this to get a better colour temp out of it. Interesting. I'm guessing I measured 240V only because there was no load. Either that or they are breaking the laws of physics.
