## Overview

The Amprobe LM-120 is a professional-grade digital light meter featuring a silicon photodiode sensor and filter, capable of measuring a wide range of light intensities up to 200,000 lux or 20,000 foot-candles. Designed for easy one-hand operation, it offers both auto and manual ranging with high resolution accuracy of 0.01 fc/lux. Ideal for optimizing lighting efficiency in commercial and industrial environments, it includes a protective soft case and supports measurements in both lux and foot-candle units.

## Description

Amprobe LM120 digital light meter with auto ranging soft case included, measures all types of visual light from metal halide, fluorescent, high-pressure sodium or incandescent sources. It is an easy to use portable light meter that is designed for simple one hand operation reading in Lumen (lux) or foot-candle (fc) units. It can measure a wide range of light, all the way up to 20,000 fc or 200,000 lux with an accurate, high resolution of 0.01 fc/lux. It features auto ranging and manual ranging with the ability to zero out the reading before it takes a measurement. It is used to measure the lighting level in the interior as well as to switch off or reduce/increase the output level of your lighting fixtures. It can be used to help ease the energy burden of the building by significantly increasing the lighting systems efficiency. 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 is 10.764 Lux and 1 lux is 0.09290 foot-candles. It includes a soft case that is designed to protect the unit from dust, scratches, dings and any other situation that may arise.

Review: Ich habe dieses Gerät gewählt weil es für einen definierten Zweck gebaut wurde. Kein multifunktionales bei dem zwangsläufig Kompromisse eingegangen werden (müssen). Es tut exakt das was es soll und das sehr präzise, ich nutze es für meine gutachterliche Tätigkeit. Ein wirklich gutes Messinstrument zu einen wirklich fairen Preis.
Review: Our superintendent Jimmy Hudson loves how it fits compact in his case and how it shows in the dark.

### ⭐⭐ Review
*by R***A on 26 March 2015*

I wish I knew if this unit was accurate. I am leaning towards no because when I put the cap over the sensor it does not read zero but jumps around between 0-18lux. So I left the cap on the sensor and then stuck it inside a black sock the blackness thereof as the inside of a coffin on a moonless night and it still did not read zero. So I removed the battery then replaced it and zeroed the unit. It still does not read zero. I have an inspection area that needs to be 600lux. When I set this unit on the table it reads 200-203lux then it jumps to over 1900lux. Looks like I will be getting a different unit. I love amazon and the internet because the days of buyer beware are over. Just hit return item and print out a UPS tag and send your troubles back to where they came.
