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. Various Types of Lighting 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 read more

The LT40 LED light meter is useful for measuring and optimizing environmental light levels in a wide range of environments, includ...ing office buildings, manufacturing plants and warehouses, university campuses, schools, hospitals and many other locations. OSHA regulates workplace lighting because illumination must be adequate for assigned tasks and light meters are used to verify regulatory compliance, as well as state and local public safety codes and ordinances. Use of LED lighting is on the rise because it is more efficient to operate, it emits stable, high quality illumination and the technology is dropping in price. Besides LED lighting, the LT40 can measure standard light sources fluorescent, metal halide, high pressure sodium and incandescent up to 400,000 lux (40,000 Fc). The LT40 comes with a built-in sensor with protective cover, 2 AAA batteries, storage pouch and user manual. read more
