LED vs. fluorescent tube is sort of like the old argument of condenser
enlarger vs. diffusion enlarger. It depends on what you want. LEDs are
very small point light sources and surface irregularities get
emphasized. That is one reason Nikon was one of the first film
scanners to provide an IR channel and software to reduce surface
scratches and dust. It was especially needed with their LED light
source. That said, with a good lens they can be very sharp. The only
reviews I have read regarding LED flat bed scannners is that they are
ineffective at scanning objects compared to those with a fluorescent
light source because of the light fall off and restricted depth of
field. Some people like to put things like rocks, leaves or even their
coin collections on the glass plate and scan them.
