Hmm, its hard to me to picture your exact situation, but i don't think she would like the lamp right on top of her cage. If you do have a lamp above her, maybe consider getting an Avian floor lamp with the full spectrum bulb.
Otherwise I think the schedule sounds fine. I don't know how your scheduled is, what I do is wake the birds up at 7 when i get up, open all the curtains, by the time I get home at 5 I can turn lights on and then they go to bed at around 7:30. The parrotlet's have little cages in the bedroom where we put them to sleep and cover them. This way they are not disturbed while we are up and about, we usual turn on a dim lamp around our bedtime for about a half hour and it does not bother them.
