You can go online to any site that carries daylight lighting (pet stores, electrical, etc) ... fluorescent bulbs. My husband made me my own light box which I put near the window to simulate sunlight and leave on for 8 hours or so a day. Helps my plants too ...nice and green. As far as too much light I have read that blue blocking sunglasses can have an antimanic effect.

Never tried it- getting out during the daylight hours helps my moods though
