“Lux” Explained for Barcode Scanning

Posted May 17, 2016

The Granit user guide has a performance chart that says – “Granit 1980i/1981i Scanner Typical Performance (200 lux).   So what is this “lux” thing?

Lux is the amount of ambient light in the area.  A full sun, no clouds in the sky, summer day would be considered about 100,000 Lux.  A completely dark area with no ambient light at all would be 0 Lux.  A typical office environment is usually between 500 – 700 Lux.  Granit scanner are used typically in a warehouse which are usually dimmer than offices.  It would be safe to say that a warehouse would measure about 200 Lux of ambient lighting.
