I was browsing through an Architectural mag and read an Ad for Solar-Powered Lights manufactured by Solatube Solatube Daylighting System and Tubular Daylighting Devices for residential or commercial daylighting and sunlighting needs are the smart alternative to traditional skylights and I am wondering if these work. If they do perform as far as lumens and spectrum then their relative high price may be well worth it (about $350 dollars.) If you haven't used these but want to review their data go to the Solatube website and clic their Technical Resources[/I][/I], choose Professional Residential [/I]and then pull down the Photometric IES menu where you can find some data from all their models performances, their 21 inch lamp with difuser beats all of them hands down.http://www.solatube.com/downloads/lumens.pdf

Additonally, also SunPowered, they have an outake ventilator exhaust fan and dimmer kit. Plus, their kits offer a model where additional lamps (to run with electric juice) may be used to supplement the light output. Also to consider are setups with lengthy tubing. They have options to run up to nine feet which is very convenient.

What are your experience or thoughts on this?
