Do fluorescent lights have a power factor?

Sure... 0.4 in the case above.

But, that said, if the undercounter light fixture say 15W, then that
is how much is used regardless of power factor

Yes.

and w=va still applies. or am I wrong...

You am wrong. W = PFxVxA.

Did you go to embassy doublespeak school? If you
did, congratulations in your studies. You
certainly confused me. You answered the 2nd
question yes and the third saying I am wrong.
Those answers are inconsistent. The subject was
totaling up the wattage or amps. If the fixtures
says 15 watts and it has a power factor, the
powerfactor is already applied. If you total it
up with other appliances you don't apply the power
factor again.

I think I'll just stick with totaling up the
wattage of fixtures/appliances.
