I don't know about making your own but my cousin uses the premade ones and said that the straight ones worked best with a polished inside surface as they brought in a lot more light.  

Seems we had some skylight info John posted.

Just for fun, I researched solar tubes.  I seem to remember that they advertise 98% + reflectivity for the surface inside their tubes.  So, just for fun, I researched the reflectivity of the shiny side of aluminum foil....98%.  Haven't actually done anything with the information, but I did find it interesting.

kimmer If you had a waterproof roof kit you could run a chase and then use cheap 1/16" mirror plates to line the chase with.

Yes, a sun tube is nothing more (or less) that a skylight with reflective walls that carry light down a shaft. At the interior there is usually a diffuser fixture that looks like a ceiling light fixture. The round commercial ones are easy to install but seem overpriced for what they actually are.
