There are some very compact, thin portable light tables selling for around
$50-$75. The lighting is very evenly distributed and, as far as I can tell
by eyeball, fairly neutral. But besides the cost they use AA batteries -
I'd imagine they'd use up a lot of batteries. And using an adaptor would
defeat the purpose.
So I use a portable light table that's not much larger - around 5"x7" - but
thick enough to accomodate four C batteries. The batteries last quite a
while but the single daylight-balanced fluorescent tube doesn't provide as
even coverage as the more expensive compact units. OTOH, it cost just $14 at
Sam's Club.
Comparing the two portable light tables, light from the flat units seem a
bit more bluish while mine appears slightly warmer. This was compared to
midday outdoor light.
I've also used it as a makeshift underlight source for macro work on custom
jewelry made by my son-in-law. And I've used it as an even more makeshift
transparency adaptor lighting source for my flatbed scanner.
