The Ace Programmable Light Control automatically turns on and off at your desired level of light. Incandescent bulbs only. Good for both indoor and outdoor use, theis device can add safety and security to your home.
NOTE: The sensor lens should not be perpendicular to a reflective surface such as glass or a lamp shade. Too much reflective light or light from adjacent bulbs can cause blinking or reduce lamp output. This is overcome by rotating the knob on the light control which varies the amount of light entering the photo eye. It is normal for unit to flicker during transition from day to night and from night to day.
