INDOOR SCENARIO
Night Lights and Ambient Sensing Energy Assessment
For sensor-triggered lights, calculate continuous standby and short lighting events separately before selecting collector area and storage.

Assessment inputs
Record day and night illuminance, trigger frequency, LED brightness and lighting duration. Storage must cover dark periods and repeated events.
This is a consumer scenario assessment, not a released-product claim. Validate with a prototype at the installed location.
FAQ
Can it be battery-free?
Do not assume so; use measured light and load data.
