Jim, that very clearly is NOT a 10K resistor, although the package looks right. In fact, it's a 25 watt package, but that's even better.

I wonder if Mexican ohms are hotter than American ohms.
A good answer is easier with a clear question giving the make and model of everything.

Yes, they are. That's why their speakers are louder. We rate our sound levels in Decibels and they have to use Tacobels.

I have also heard that the good old magnetic transformers - the ones used for spotlights e.g 50W - make very good dummy loads and will fool the dimmer into seeing a bigger load.

Has anyone tried this or can confrim the theory behind this?

P.S. Can people post the retail price of the lutron and Litetouch pieces?

I think Lutron's is $170 or somewhere around that.

So many competent electricians here - can anyone explain if the above is valid and why? Is it because of the losses? Do you still have losses if there is no lamp load on the transformer?

Have you ever heard of anything that is 100% efficient?

Since nothing is 100% efficient, then the transformer will still have losses, even if no current is consumed.

People think that the 120V 60Hz power in their homes is not being used while they have nothing connected... but that is not true! There is capacitance between the wires, so energy is consumed to charge and discharge that capacitance every cycle. Even the power company's transmission lines and the power distribution in our homes and businesses is lossy.
