LT40 & LT45

LED Light Meters

Extech LED Light meters are used for monitoring and optimizing environmental light levels in

buildings, schools, and offices. LED lighting is being used more commonly, because they

are less expensive, more energy efficient and brighter. Model LT40 measures the light intensity

for white LED lights, while the LT45 measures both white and color LED lights.
