[DeTomaso] Hot Dimmer Switch

[F&D Terry]

I have a very limited knowledge of the characteristics of electricity 
but wouldn't a rheostat of a higher wattage rating heat up less? Just a 
thought.

Now that dimmer runs hot.  It gets so hot that I'm pretty sure if given enough time,  the bezel will be too hot to touch.  My main concern here is fire.  Has anyone out there replaced their rheostat with something a little more efficient?
