It's for my personal use sana. The other guys can keep lugging the big xenon light source around. :D

As for CFL, I don't think they'd cut it. We need projected lighting such as on those halogen OHP bulbs because the light has to be trasmitted through a fiber optic light cord (see image) which is connected to a flexible or sinus endoscope which is stuck up the patient's ear, nose, or throat.

Fiber optic light cord:


My job (that's not me):


The thing stuck in the patient's nose is a sinus endoscope, the cord leading down from it is the fiber optic light cord which is plugged into the xenon light source.

A camera can also be attached to the endoscope so you can look at it from a video monitor (that's an upcoming project also).
