What is the relationship between torch batteries and bulbs.
I have a couple of old torches using 6v batteries. So I need 6v batteries ?
Two 1.5v batteries need 3v bulb and so on.
If the exact match is not available do I choose the next bulb up in voltage or down and what is the effect?

You should use the same battery voltage as the bulb voltage. But you can add batteries in series, like two 3-Volt batteries will work as a single 6-Volt battery. If you use a different voltage than that prescribed you will have either a dim bulb or an over bright bulb that will soon burn out. Try to match as closely as possible.
