I'm having some (12 or so) new halogen spot/down lights fitted and I'm trying to choose between 12 volt or Mains
A few years back 12 volt spots started to emerge on the basis they used much less power and produced the same light - i was never really convinced by this
I notice you can also buy 240v halogen spots now - in fact i notice Wickes don't seem to stock 12 volt at all
I'm looking for pro's and cons?
