Robust but simple device

The device makes a robsuten impression
the housing is made of ABS, the display is large and easy to read.
But you have saved on the decimal point at the screen,
the respective value must be converted over the measuring range.

Unfortunately, the device is only limited to professional
Lighting control in office buildings suitable
because the maximum sensitivity of the sensor in the spectrum of
Sunlight is.

Light bulbs and fluorescent lamps, and especially
Energy-saving lamps have a correction factor of
2 - are rated 4.5.

At best, for the hobby a nice gimmick.
Flashlight fetishist come with relative comparative measurements
with this affordable device at your expense.
