A quote from the video: "People love natural light and they can't get enough of it”. Plants love it even more and usually can't get enough of it inside buildings. It is the limiting factor (along with education) in the growth of urban greenscaping both decorative and edible.
The future growth of urban greenscaping is clearly aligned with our ability to create more light in buildings. LED technology will have the most impact but I believe we need to do much more than we are currently doing to advance natural light engineering in the built environment.
These Solatubes (search on "light tubes" and "solar tubes") are an intriguing technology that I would like to know more about from first hand experience. In my view, architects (and landscape architects) need to have a much better understanding of the human need for plants in buildings in urban environments. From long experience in the field (particularly in interior plantscaping), I have observed that the architectural profession is not well versed in plant science.

Every day, we at Solatube® International challenge ourselves to find an affordable way to bring daylight into dark spaces where natural light had rarely been an option. One thing is clear. Our products are not skylights. They are high-performance daylighting systems that use advanced optics to significantly improve the way daylight is harnessed.

Our customers love the natural light they get after installing solar tubes in their home or office.
Our company ECO Solar Skylight Tubes - http://tubesolar.net, offers the same product but from a different manufacturer. Compare our prices to theirs!

Looking to grow plants using solatube. What is the candle power? What is the wavelength? Any data would be appreciated.
