Has anyone tried to make a solar light tube

I already have sky lights installed in an unfinished attic. I figure I could try lining some heating duct with some of those Mylar emergency blankets, butt it up against the skylight and then install a modified recessed light fixture in the ceiling. Connect the tube to the light fixture and it should work the same as the $300 units. I understand the effect the dome could have on collecting light, I do have some security camera domes, but don't want to go cutting holes in the roof unless it will work. ???anyone Thanks

I installed a skylight in my apartment... the people who live above me are furious! -Steven Wright. I can't help but to ask if you've exhausted your wall window addition options. if you have experience framing walls and following directions it could result in the best light per cost. of course, the devil is in the details...

I've seen this done with lots of small fiberoptic cables and a solar tracker. It's a neat idea.

How much more light might you to expect to get over the existing skylights? L

Well the skylights are somewhat closed off because it is an unfinished attic. So the skylights are there, we just do not see them.
When you've finished will they let in a lot of light in, or do you think you're in need of making more holes in the roof? Or have I missed something, and you want to pipe light through the attic to a room below?

Yes, that's exactly what this person wants to do. There are companies that sell prefabricated (and relatively expensive) versions, but it ought to be possible to make something comparable by hand. They actually do collect a surprising amount of light. The mirrored inner surface of the duct means that light over more 120 degrees of view gets reflected down and out into the room, about the same as having the flat skylight directly in the ceiling.
