It would illuminate about the same as a bright full moon, yes.  It
would be a very dazzling star, apparent magnitude probably about -13.
I don't think it would actually be dangerous to look at: despite the
pointlike focus on the retina, the light passing through the pupil
would be less than a microwatt.

It would be a very obvious brilliant point in the day time sky, yes.
More than a thousand times brighter than Venus at its brightest.
