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 foot candle (fc) units. The LM-100 measures a wide range of light up to 20,000 fc or lux with an accurate, high resolution of .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 foot candle = 10.764 lux and 1 lux = 0.09290 foot candles.
Easy to use
Just got to use this today for the first time. Very easy to use. Just turn on and pick your range. No more arguing that its too dark when trying to meet corporate specs.
✔ Yes, I recommend this product.
A bit disappointed!
The body is not finished well. Also I have bought LM 120 and I see certain difference in reading between the two under exact illumination. Also nowhere in the body it is written that the product is from USA.
✘ No, I do not recommend this product
