I use 6v bulbs, 15 Watt.

I struggle to get hold of them locally, could I use a 12v bulb? And if so
what wattage would be best?

My understanding of bulbs is that electricity passes through the filament,
it gets hot and glows, so there would surely be interchangeability,
is this
about right?

Cheers,
Rick

Mail order?
