Thermo Cube Thermostatically Controlled Outlet

This is a great Thread.. Yes, I use that very product, it controls the lights that keep my water hose warm when it gets too cold.

I also use the Frost King one that someone else pictured, it controls the lights that are under my Fresh water tank and the 100 watt lamp in the other end of the wet bay... (It is inside the bay where as the Thermo-Cube is outside so it comes on first)

Both work very well.
