Hi Keith

Skylight, yes that's the best, ( in the day time only )G.
I have and I think it's best to have, fluorescence plus incandescent
lamps/bulbs.

I have several (5) 4 foot fluorescence fixtures, couple halogen
spotlights and a double jointed desk light that can be (and is) moved
around for the best position.
You have never enough light it seems, my best friend who is a retired
industrial electrician, scolded me for not buying High Output (HO)
fluorescent lights, he said they give a lot more light and the lamps
last a lot longer, they apparently don't give you the strobing effect
either ( I think they are also more expensive ) maybe next time I will
get one or two.

You should keep the light that you can get from your window also in mind
when placing your lathe, if you are able to have the window light from
the tailstock end it should be very useful and not interfere with your
vision I would think.

Have fun and take care
