She will adjust, but one thing you might do is to leave her up with your husband till around 11-midnite and then have him bring her to bed so you can nurse her. Then she may at least want to sleep earlier. That's what we did with my older son - he was and still is a nite owl. The nursing that often is actually perfect at this age. And, it might actually help to push it to every 2 hours during the day - that may lengthen the time she can go at nite.
Also, for the light thing, perhaps getting a dimmer switch, so you can gradually adjust the light to a lower and lower level everyday, so that eventually she's accustomed to the dark. And, again, there's no reason if you nurse her at 9-10pm that you can't get 2-3 hrs of sleep before the next nursing. My younger son was very much this way until about 2 mos and then it's like a switch was flipped and he got so he would go to bed early, nurse at about 2 am and then wake up 5-6am for nursing. Now, he was an early bird - I found this harder overtime than having a night owl as I got no time to myself in the morning until he hit the preteen years.
Anyways, good luck - I always found that you have to try a few things before you hit on what works for you both. And, again for us, bringing the baby to bed at nite worked best for everyone to get sleep - for my younger son, we did the "sidecar", with his bed by our bed.
