i heard many non-professional scanners use fixed-intensity fluorescent
tubes, that means user can not really control the the scanner's
hardware exposure. is Epson's 4870 scanner fall in this class?
thanks.

Exposure isn't just intensity of light, it's also length of time.
Doubling time= doubling light.
