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
illuminance of white LED lights, while the LT45
measures both white and color LED lights.
Both meters can also measure light levels for
Fluorescent, halogen, and incandescent lights.
