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.
