The Tork 2000 conduit mounting photo control is designed for use with outdoor security lights, patio lights, walkway lights, parking lot lights, decorative lighting and LED fixtures. It has a 1/2-inch conduit mounting in a fixed position. The translucent Lexan enclosure is impact and vandal resistant and prolongs cell life by screening out ultraviolet rays. Both the dome and base are ultrasonically welded for maximum strength. It controls 2000W of Tungsten lighting and functions in temperatures ranging between -40 degrees Fahrenheit and 140 degrees Fahrenheit. The thermal, SPST switch has a two minute delay preventing false switching due to car lights or lightning. The easily adjusted on/off switch requires no tools to adjust the light level selector. This photocell works on 120 volt systems and the 6-inch, three color-coded wiring leads make attachment to any 16 AWG wiring easy.
