Light 2
If Sun 180/-060 Then ON

I've been using it for a few years. They're on for around 8-9 hours a day and the change over the course of the year isn't significant. I don't feel that it does anything special for the tank nor does it harm it. I simply wanted to use the option because it was there. The seasonal temperature fluctuation on the other hand may have adversely effected the tank while I was using it. So recently I went back to a steady 78F.
