My Fluke multimeter has a diode tester and with it's internal 9 volt battery also illuminates the LED when checking it.

What voltage did the meter read when the LED lit up in diode-test mode?

The diode-test mode injects a small test current of, say, 1 mA and then measures the voltage across the diode. 1 mA would illuminate an LED but I can't imagine it lighting up a 14V 50 mA grain-of-wheat incandescent bulb if that's what is used in the non-LED version.
