What is the advantage of using a Electronic Dimmer instead of the Rheostat type?
74600-02 Electronic Dimmer Solid state devices dissipate very little power. They are either fully on or fully off. The power dissipation of a Rheostat Dimmer is proportional to the maximum load current, independent of the position of the dimmer. The energy used to overcome the resistance produces heat. Electronic dimmers are not load sensitive. Changing the load (for example by adding or removing a light) will not produce a noticeable difference in brightness of a light. Electronic dimmers are considerably more efficient. There is less loss in the feed cables and substantially less loss (more than 50 times) in the dimmer unit itself.
