What Is a Light Meter?

A light meter measures the amount of visible light, also known as illumination, in a given area. 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.

There are many different types of lighting that can be measured. the most common are: sodium, tungsten, mercury, and fluorescent. The following list shows common applications for each lighting type.

Sodium lighting: Highway, parking lots, security measurements
Tungsten lighting: Sunlight and incandescent lighting measurements
Mercury lighting: Highways, parking lots, stadiums
Fluorescent lighting: Indoor lighting for workstations and store display areas
