Test
Measures both lux and foot-candles at a rapid sampling rate of 0.4 seconds. Display update rate is adjustable to 1 or 2 seconds.
Large LCD shows separate readings for lux and foot-candles in 1.375 in. H digits, plus selected source (daylight, tungsten, fluorescent or mercury).

Extech LT40 Light Meter for White Led and Standard Lights
The LT45 LED light meter is useful for measuring and optimizing environmental light levels in a wide range of environments, including office buildings, manufacturing plants and warehouses, university campuses, schools, hospitals, and many other locations. OSHA regulates workplace lighting because illumination must be adequate for assigned tasks, and light meters are used to verify regulatory compliance, as well as state and local public safety codes and ordinances. Use of LED lighting is on the rise because it is more efficient to operate, it emits stable, high quality illumination, and the technology is dropping in price. The LT45 comes with a 9-volt battery, protective sensor cover, hard case, and user manual.
This meter measures light intensity up to 400,000 lux in five ranges and 40,000 footcandles in four ranges. Unit is color and cosine corrected. Large LCD simultaneously displays readings numerically and in a bar graph format. Meter utilizes a precision silicon photodiode sensor to obtain readings.
