Overview

The Extech LT40 and LT45 LED light meters are used for monitoring and optimising environmental light levels in application such as buildings, schools, and offices. LED lighting is being used more commonly, because they are less expensive, more energy efficient and brighter. The LT40 model measures the light illuminance of white LED lights, while the LT45 measures both white and colour LED lights (red, yellow, green, and blue). Both meters can also measure light levels of fluorescent, halogen, and incandescent lights.
