There may be instances where a room is either too small or it is otherwise undesirable to have a second light fixture in the ceiling. Natural Light has an ingenious solution! The light kit can be installed in the previous fixtures ceiling rough out or can be added anywhere with additional electrical wiring. The incandescent light fixture is mounted inside and is wired to the wall switch. Your Natural Light tubular skylight is now ready to serve for evening illumination! Check local building codes or call us for more information. **Double sockets will not work well with smaller tubes. Please use double sockets in tubes larger than 18" only and you should use 60-watt bulbs in these connections.
