Here is a report on the cost of using natural light from Sun Tunnels over electric light. It also explains the effect on the air conditioning system. Electric lights do heat up the interior space that it lights. This means that turning off the electric lights and harvesting the sun's light during the day, when air conditioning use is at its peak, results in significant energy savings.

They give you a good look at the contrast between natural light and fluorescent light. When you are in fluorescent lighting you may not notice the yellow tint to the lighting. I work outside so I notice the darkness with electric lights. The shot in the video shows the different colors of the light. Natural light is cheerer and easier on the eyes. This makes for more productive environment.

Tubular skylights are the most cost effective way to reduce your energy bill. The estimated payback period for this project is 4 to 6 years.  After that it amounts to cost savings year in year out. This is why daylighting is becoming so popular.

For residential users it is harder to see the economic impact on your budget. The comfort of using natural light will be a more important factor in choosing solar lighting.
