Extech LT45 LED Light Meter

The LT45 LED light meter is useful for measuring and optimizing environmental light levels in a wide range of environments, including 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.

The LT45 uses a detached light sensor connected with a coiled cable (expandable to 59 inches, or 1.5 meters) to measure both white and color (red, yellow, green, blue, and purple ) LED lights, as well as standard light sources — fluorescent, metal halide, high‐pressure sodium and incandescent — up to 400,000 lux (40,000 Fc). The LT45 can also store and recall up to 99 recorded light-level measurements.

The LT45 comes with a 9-volt battery, protective sensor cover, hard case, and user manual.
