Had solar tubes.

NEVER again.
Heat Gain in rooms during daytime hours was significant.
Every month the 4 to 6 days of Nearly Full and FULL Moon
brought in TOO MUCH light at night.
Lightning at night made rooms EERIE, to say the least.
During full moon at night, the slowly moving ceiling fan caused
dim/bright - dim/bright real bad.
Compare the flash effect of the fan blades temporarily
blocking the moonlight to strobe lights on

a police car..
Was driving me mucho loco.
Was going to paint the lens covers in the house with blackout

paint,
then had a temporary flash of sanity and found

someone
to install

L.E.D. lights which fit the circular opening .
Also put them on dimmer switches.
Problem Solved.
