Another way to let more light into your home is by installing solar tubes. They work well in places like hallways and bathrooms, spaces without windows. They are like a skylight in that they originate on the roof, letting light in from above. Though in most cases, they are smaller than a skylight.
Solar tubes, also known as Tubular skylights, range from 6" to 18" round. At the roofline, they look like a dome. The dome material is transparent acrylic, Polycarbonate plastic, or glass with a rubber or plastic layer that serves as flashing under the roof shingle to prevent water penetration. The light travels through a metal circular tube through the diffuser and a reflector which will direct the rays toward the circular glass or plastic piece attached to the room's ceiling. The diffuser inside the tube helps distribute the light into the room even on a cloudy day. Diffusers can range in type depending on the amount of light you hope to gain and whether you are looking for a warmer or cooler effect.
It is estimated that a 10" Solar Tube gives off around the same amount of light as three 100 watt light bulbs on a sunny day.
Another benefit is that solar tube installation qualifies for tax credits under the Solar Energy system tax credit program. Currently, 26% of the cost of the installation.
