Artificial light for tolumnia

[wtstuller]

Hey everyone,

I live in central Indiana and the winters here are very cloudy and cold. I am looking to move my tolumnia to artificial light, but have no idea what to look for. I know most genera (I have jairak rainbow) prefer anywhere from 2,500-4,000 foot candles, but what would that correspond to in watts? Do I need to purchase a special bulb, or would a compact florescent work? Also, does the standard 16-hour "day" apply, or does that vary also?

I should also mention that I have a miniature cattleya who lives with them

Any insight would be much appreciated!
