Hello All,

We've had some queries about using the SQM products for measuring light
during twilight. The SQM meters are mainly intended for night time
readings and will saturate in daylight. However, with the addition of a
Neutral Density (ND) filter over the light sensor, the range of readings
can be shifted to be useful in brighter settings.

Here is a page dedicated to some of those questions and applications:
