LuxMeter enables the measurement of illuminance directly from your smartphone.
Imagine you want to evaluate your home lighting conditions, whether your new light installation provide enough visibility in your living room or at your working space.
New smartphones feature ambient light sensor which are very accurate, enough to give you confidence about your home lighting design.
To have a rough idea of the values you should expect, please consider real world lighting scenarios below:
1lx-10lx: very dim light, e.g. a candle from 1m distance
10lx-100lx: diffuse light in a room, e.g. a 60W 800lm lightbulb at 1m distance gives approximately 64lx
100lx-1000lx: soft daylight, or, e.g. a set of 3 100W 1600lm lightbulbs at 1m distance give approximately 384lx
1000lx-10000lx: daylight
Recommended light levels:
