For many meter brands, including Extech, illumination is expressed in units of measure called Lux (for metric) and Foot candles (used in the US). To use an Extech light meter, the sensor is placed on a tabletop or other surface in the area to be measured and the light level reading is indicated on the meter's display. Various types of lighting There are many different types of lighting that can be measured. The most common are: Sodium, Tungsten, Mercury, and Fluorescent.
