Digital BW, The Print

I found a moderately priced Tensor desk lamp at an art supply store
that uses a 15 watt "6400K full spectrum" helical flourescent bulb.
One reason I got it was that I simply could not judge colors or toned
prints with my tungsten lighting, or (ironically) the flourescent
replacements that are designed to give tungsten-like light.

I don't know how well balanced the bulb is--I find it a bit on the
cold side--but it's good enough: I find I can judge color fairly well
under the lamp plus the ambient tungsten. It does take a minute to get
to full brightness, but there is no flicker as far as I can tell. One
unexpected benefit: reading text is much easier. (Makes sense, I
guess--full spectrum should give max contrast for a wide range of
text/ground combinations.)

Potential issues: I haven't found a source for replacement bulbs, and
there may not be enough light to judge a very large print as a whole.
The only solution I've come up with so far for either issue is to buy
another lamp.
