Solartubes are great,
My sister had a few installed and made her trailer very well lit. One time an electrician came in to do some rewireing on the trailer and made several trips to the breaker box and finally came back and asked her " where is the circuit breaker for these lights" he was pointing to the solartubes :-laf
I have put in a 10 inch in my bathroom($300) and it really works great. I will be installing a 14 inch in the kitchen if we don't sell the house and relocate to Spokane.
