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?
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?
