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 LLT45 measures both white and color LED lights.
