There are quite a few reasons. Dimming alone greatly reduces energy consumption
and may pay for itself through energy savings not to mention extending
bulb life 10 times or more.
Lighting systems that combine occupant sensing can also turn lights on as someone enters a room and then off
when they leave saving energy from leaving lights on when not needed.

All dimmers rely on heat conduction and convection to keep the electronic components cool. Derating is the reduction of the maximum capacity (load) a unit can reliably handle when fins/side sections are removed.
Dimming increases incandescent lamp life, and halogen lamps are
incandescent lamps. Lutron test data suggests that all halogen lamps
will have an expected lamp life similar to that of other incandescent
(non power factor corrected) lamps when dimmed, i.e. a halogen lamp
dimmed 25% has a life extension of about four times that of a
