Solar tube lighting solution - GIF

[datsun240]

I have 6 of these Sola Tubes in my house. They are extremely bright, my electric bill is very low. I wrapped the tubes the attic with R-15 insulation.
Only downside is the covers on the roof look ugly, industrial. I mounted mine on the back roof. I had them installed 20 yrs , no leaks , lens still clear.
