Data Sheet

LM-100

Light Meter

The Amprobe LM-100 light meter measures the visible light
from fluorescent, metal halide, high-pressure sodium or
incandescent sources. It is a portable, easy-to-use digital light
meter designed for simple one-hand operation reading in
Lumen (lux) or footcandle (fc) units. The LM-100 measures a
wide range of light up to 20,000 fc or lux with an accurate,
high resolution of 0.01 fc/lux.

Use the LM-100 light meter to measure the illumination level
in the interior and to switch off or reduce or increase the
output level of lighting fixtures. Reduce the energy burden
of the building by significantly increasing the efficiency of its
lighting system.

One lux is the illumination from a one candela lamp
perpendicular to a surface one meter squared at a distance of
one meter. One fc is the illumination from a one candela lamp
perpendicular to a surface one foot squared at a distance
of one foot. 1 footcandle = 10.764 lux and 1 lux = 0.09290
footcandles
