Usually it is a simple flourescent bulb. I use the ones made by Phillips sold at Home Depot . . . less than five bucks, and the scanner's calibration program adjusts for color temperature.

If and how does this light affect a light sensitive object such as a photograph? Is the duration of exposure too short or is the light intense enough?

If you don't leave a photo in the scanner, it shouldn't have a bad effect on most stable photos. Probably a good bit of UV emmitted, so be careful of long exposures.

How could measurements best be made?

Dunno.. just be prudent.
