Amprobe LM-100 Light Meter with Silicon Photodiode and Filter

The Amprobe LM-100 light meter measures up to 200,000 lumens per square meter (lux) or 20,000 footcandles (fc) of light output from fluorescent, metal halide, high-pressure sodium, and incandescent sources, has a silicon diode sensor and filter, and is designed for indoor operation at altitudes below 2,000 meters. The meter has manual ranging, a data hold feature that freezes readings on the display, and angled light cosine correction to calculate the amount of light, regardless of the light's angle.

The meter is powered by a 9V battery (included) which has an average life of 200 hours. The sensor has a 1.5-meter wire for positioning the light sensor, and a protective sensor cap.

Specifications

H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Light meters measure luminous intensity, or light, and are commonly used in a wide range of industries and settings including photography, video filming, galleries, schools, laboratories, and greenhouses to help determine the brightness of light.

Amprobe manufactures electrical testing equipment for commercial, industrial, and home use. The company was founded in 1948 and is headquartered in Everett, WA.
