She's just dug out a fibre optic santa, purchased a good few years ago
for silly money no doubt from QVC. Once again she's lost all the
transformers for everything FFS. Same every year. removes all power
supplies from all lights, decorations etc etc and mixes them all up in a
bag and loses it.

So FibreOptic Santa has a 12v 20w Halogen bulb up his arse. I was
wondering if it could be replaced with an LED bulb, whether the light
would still pass effectively down fibres and give the same effect and if
so, whether a regular wall-wart would suffice or would it need to be a
special one?

Cheers
Pete
