yeah, I hear the same rhetoric from the dimmer guys too. I cornered one once and finally got him to admit that you saved money, but you were getting less light and paying more for it than if you were running a lower wattage bulb. I'm no authority but logic and my understanding of the workings of the universe tells me that you get what you pay for. You pay for light and you pay for heat. A 60 watt bulb dimmed to 50% will cost 40% less than no dimmer. But a 30 watt bulb will cost 50% less. I think it is very misleading the way these dimmer companies market this way.
