I won't add to the plants listed previously. However, I do know from experience that most folks tend to overestimate the available light. An east window can be good for low light plants provided that the window is not too small, is completely uncovered throughout the daylight hours and is not blocked outside by leafy trees, roof overhangs or large buildings. Even then, if you place a plant more than about 4-5 feet from the window or off to the side of the window, the plant will not get adequate light. I know those are a lot of factors to take into consideration, but that is why many folks over estimate the light for their plants and then wonder why they don't do well.
As a general rule of thumb, low light for plants must be bright enough to read newsprint comfortably for at least 8 hours each day. Incandescent lights will not help your plants, although they certainly help with reading!
