I can't help with the lighting problem, but some nice low light plants are the anubias varieties - there's lots of them, with leaves of all different shapes and sizes, I actually brought a new kind (for me anyway) today with the tiniest leaves I've ever seen in my life! Java fern - again, there are lots of different varieties of this, each more unique looking than the last. And bolbitis (the African kind) grows okay under low light as well... Hopefully someone else can chime in and help you with your lighting problem.
I currently have four anubias varieties with leaf sizes ranging from the size of my palm to the size of my pinkie nail, one "trident" (as i was told its called) variety of java fern and bolbitis in my tank and all are - should I say were - doing alright until the algae took over, and I have the worst lighting available, 2 t12 fluorescent tubes that were purchased from the hardware store.. These plants are tough as nails!

To the OP, if you do get any of these plants make sure the rhizome isn't buried in the substrate or it will rot, all of them can be attached to rocks and wood (that's how mine are currently) but can be placed in the substrate, just make sure the rhizome isn't!
