Are 12 volt lights cheaper to run than 240 volt lights?
there is no such thing as a free lunch power consumption is
directly proportional to current draw firstly you need to convert
mains voltage to12volt via a transformer the advantage to 12 volt
lighting is only recognised when using lower wattage halogen or led
lighting. as far as i am aware the use of a mains voltage 100watt
globe draws the same if not slightly less than a12volt 100watt
light as the transformer uses power (in the form of heat) to
produce 12volt at least this is what all my "sparky" contacts tell
me . my own experience has shown led lighting to be the way to go ,
i am using a small deep cycle battery ,a small solar panel and leds
so far so good with more and more 12volt led lights becoming
available
