Therefore you can use a lower wattage bulb than you would if you used a standard one and this is where the savings are made. If you look on the box of an energy saving bulb it will give the wattage of the bulb and an indication of what wattage standard bulb you would need to get the same amount of light.
Hope this makes sense

I understand that, it was the low voltage bit that was confusing me. I thought low voltage would mean less cost but apparently this is not the case. I was debating between a flourescent tube and low voltage halogen spots. I was told a 50watt 12v halogen bulb would use the same energy as a 50watt 240v bulb. Just wanted a comparison of costs. Although after working through the sums voltage plays no part in the costing, so now i'm thinking i've been told right.
