The Precision Lumatrol T-30 stem mounting photo control is a great choice for walkway lights, parking lot lights, and security lights and is designed for high vandalism locations. The Lexan housing is 20 times more resistant to high impact objects, like rocks and bats, than a standard plastic housing. The wire-in control is designed for applications where more load switching is needed than a standard 15 amp series can handle. The unit functions in temperatures from -40 degrees to 170 degrees Fahrenheit and the SPST switch is capable of handling 3000 watts. The unit fits a 1/2-inch knock out, comes with a 1/2-inch, 14-thread stem, and includes moisture proof, three color-coded 6-inch leads. The external light level slide makes on-site adjustments for earlier or later on/off times simple.
