Manufacturer illumination ratings cannot be trusted, so you should use a lux meter and test yourself. Some people, though, are too lazy to get their own lux meter or want to use an application that can be loaded on their smartphone. However, this begs the question - How well do these applications work?
We tested 2 iOS and 2 Android mobile device apps named "Lux Meter" and "Light Meter". You can find these apps on either the Android Play or iOS App stores respectively.
The only paid app was the iOS Light Meter for $1.99 USD. All other apps were free.
In this report, we:
- Test the performance of 4 mobile light meter apps against a professional Extech light meter, which acted as our baseline.
- Compare lux measurements in a variety of scenes, highlighting the pros and cons of each app tested.
- Offer feedback on device and app usability.
