Measure light with Lux-o-Meter for Windows Phone

You can now use your Windows Phone device as a lux meter thanks to a new app that has just released called Lux-o-Meter. It measures brightness or illuminance using the built-in light sensor. The sensor is usually next to the front-facing camera on your device. Go ahead and check where it is on your phone.

Head past the break to watch our hands-on video and walkthrough with Lux-o-Meter.

Lux is the unit of measurement displayed by Lux-o-meter. It goes from 1 all the way up to 65,536. A lux meter can be useful in photography and videography as it can help make sure scenes filmed in different light levels have a consistent brightness on screen. It can also be used to check whether a room is bright enough to meet any rules designed to protect workers, for example.

Lux-o-meter is a free download from the Windows Phone Store. It displays ads on top that can be removed by upgrading to the Pro version. The upgrade costs $1.49. What would you use the Lux-o-meter for? Let us know in the comments!
