Blady blady blah
what a load of shat it is a con for the colder times of the year and here is my opinoin why
in the summer you hardly use lights but
95% of a incadesant lamp energy dissapates in heat so in the winter yer house is cold and your heating has to make up for the 95 watt of heat lost from a 100w lamp
Save in one hand spend the same from the other
