These will actually need quite a bit of light indoors to be happy. I would recommend at least 100 to 200 watts per tree to satisfy its light requirements.
Another thing to note with indoor citrus in container, is that they will need regular fertilization. Once a year, you should put a citrus fertilizer, along with some dolomitic lime, and iron sulphate to keep the soil conditioned.
