We install many Sun Tunnel Skylights each year (also known as Sun Tubes or Solar Tubes)
We recommend Rigid (solid Tubes) and only install flex tube when absolutely necessary.
Ridge Tube is 20% brighter on average but can be as much as 60% brighter on longer tube lengths,
Additionally only sun tunnels with the ridgid tube qualifies for the solar tax credit.
That tax credit saves an average of $300.00 per unit for our customers
