For all this effort you might consider just using an incandescent light source.
I want it to be able to run off a battery for a decent amount of time.

PWM might drive up the complexity and cost, especially if you're in a DIY mood. What about simply installing switches that turn off/on individual rows in your light?
As for power, I have a ton of old 12 volt laptop supplies laying around that I can use for mains power and for battery power I was thinking of using some of those big LiPo packs they use for RC planes as they're inexpensive, have impressive power density, and can handle whatever current I need to pull out of them.
