LUX is defined as “Relative amount of light that will produce a viewable image.” A unit measuring the intensity of light. Full moon light is about 0.1 lux whereas full daylight is about 10,000 lux. Most color cameras can produce decent images during deep twilight. Most black and white cameras need about as much light as produced by a full moon. With our new HAD and Super HAD CCD cameras, the only light you need is starlight on a dark night.
