That's one of the reasons that I use the circular florescent magnifier light...I've had brighter ideas than the light that's equipped with my saw...I even think that the bathroom night light is brighter than the saw's built-in light.
Get a good light even if your room is well lit...I perform non-destructive testing in my job...While performing visual inspections, a good light source is required to see fine details...Under the wrong lighting conditions (what most of us consider bright enough), lots of stuff can get overlooked...Ambient lighting, even in something like a well lighted office/classroom/etc, isn't enough by itself...You need a decent light source focused on what you're looking at...At the same time, don't go overboard and get a light that's so bright that you end up blinding yourself or getting a sunburn from the reflection off of the object being illuminated.
