The 120V 50/60Hz 1800W "T" FIX MOUNT The K4000 Series Fixed Position Mounting Photo Controls are thermal-type photo controls that fit into a standard outlet box, post lamp, or wall pack. The photo controls provide dusk-to-dawn lighting control, along with a delay action, which eliminates loads switching OFF due to car headlights and lightning. The thermal-type controls feature a cadmium sulfide photocell and a sonic-welded polycarbonate case and lens to seal out moisture. The design utilizes a dual temperature compensating bi-metal and composite resistor for reliable long life operation over ambient temperature extremes.
