AW-L Actigraph with
Integrated Light Sensor

The Actiwatch-L actigraph has a small, very high performance light sensor integrated into its case in place of an event marker. With each activity record that is recorded, the light level is also recorded in Lux.

Like all of our Actiwatches, the AW-L uses actigraphy principles to record activity information and can be used to analyze sleep quality.

The AW-L may be used to verify time, length and frequency of treatments for SAD patients (Seasonal Affective Disorder). These values may be correlated with changes in sleep/wake patterns from the actigraphy record.
