One thing to consider though is color quality. I thought about using LEDs,  
and was shocked how bad the colors looked when trying a LED flashlight for  
illumination under the stereo microscope compared to the built in  
incandescent light. That quickly buried the idea of a LED light there.  
Maybe different better LEDs are an option, but mine clearly weren't.
