Talk:Dimmers & Switchbanks

Although not my original edit, the bit about energy efficiency was probably better before you changed it ;-)

You seem to be confusing lighting efficiency with energy efficiency. A dimmer reduces lighting efficiency, i.e. you get less light per watt, but increases energy efficiency, i.e. you reduce the overall energy consumption. That fact that the fall of in light output is not proportional to this is not relevant - especially when that is the result you are seeking to achieve.
