I think it’s 12V.
When I get home later, I’ll have a quick look. I swapped mine for a lower-wattage one back then, as the burn times were too short for me...

So can any bulb be used? The FOTOIMPEX catalogue states:
"If your device requires a halogen bulb,
please note not only the voltage
and wattage but also the base. Only when
the three-letter code (e.g. ESJ), the
voltage and the wattage match will
the bulb actually fit. Please note: every third time
you change a halogen bulb, the
base should also be replaced or at least cleaned.
Otherwise, the bulb may
burn out again after a short time."
What exactly is meant by ‘base’?
