Answer: There are several different types of Chamaedorea cataractarum but a typical lighting recommendation would be about 3000 foot candles. This means moderately bright -- but indirect -- light.(These palms are actually native to rain forests.) Direct west sun would be too intense, but you might be able to filter it with a sheer curtain. Your tree will also need high humidity to stay healthy. Here is more information about palms as house plants you may find helpful.
Good luck with your new plant!
