Doesn't make much difference, IMHO. Just have plenty of them, don't
have them casting your shadow over the bench, and modern ballasts will
work better in cold weather.
If accurate colour rendering is an issue, then go straight to
incandescents. Cheap portable halogen floods are convenient and good
enough for most uses, or you can go for an atrtist's "blue" bulb
(which need to be over the bench, as they're tiny in the space of a
workshop).
I've worked on framing in a barn under low pressure sodium (the yellow
streetlights) before now, which really _is_ annoying

Matches my experience exactly.

To this, though, I would add "if the piece will be placed or used
indoors." Of course, this is the usual case. Bottom line: when accurate
color rendering is important, use the same kind of illumination the piece
will receive in use. If it's a swing or park bench, finish it outside.

Eye strain is likely more a problem with insufficient light or poor
light distrubution rather than light colour.
Look for full spectrum. They are the closest to pure white and are,
unfortunately, the most expensive. I've seen them occasionally at the
borg. Don't confuse them with Daylight bulbs, which are similar to
cool white (but if you live near the tropics, you might prefer daylight
bulbs). In the absence of full spectrum, some folks put one cool and
one warm white in a two bulb fixture. I've tried cool/daylight in a
fixture, but prefer full spectrum.
I've seen full spectrum for T12 (? the common ones) but not for the
newer T8. They exist, AIUI, but haven't seen any.

~5000k tri-phosphor T-8 bulbs with electronics ballasts are
recommended - by me anyway... ;-)
Electronic ballasts switch at ~20kHz, and get rid of the 60 cycle
flicker than many people find annoying with fluorescents.
This particular color temperature resembles natural sunlight and makes
colors seem more natural. When doing finishing work, they are helpful
in avoiding the surprise colors that show up after finishing a piece
under warm white or incandescent bulbs.
FWIW,

There is a company named Ott-Lite that makes
bulbs and light fixtures that are color correct
but on the expensive side. They have 24" and
48" fluorescent replacement tubes, try this link:

The SWMBO has one of their light fixtures over
her craft bench (read my old drafting table!)
and it is bright and white.
