Professional light intensity (lux) meter for your device.
It measures illumination levels in lux.

■ direct reading in lux
■ 0 to 1000lux in 2 ranges
■ up to 300000lux in ICS+
■ automatic range change
■ support for neutral filters
■ 5% max error (device dependent)
■ predefined and custom calibration
■ sensor linearity correction option
■ alternative display in fc (foot-candles)
■ display of light color temperature in K
(available only on supported devices)
■ realistic vintage analog look
■ tablet support
■ 18 case skins
■ free

This app requires devices with a light sensor. It uses native light sensor data acquisition that gives accurate and instant light intensity reading. This type of native data acquisition is available for many supported devices.

Other devices are also supported by the built-in compatibility mode but the accuracy and the speed of light intensity reading may be limited and custom calibration is required for correct reading under compatibility mode.

Custom calibration procedures are described on the following page:

Also, on some devices the light sensor may not be linear, not continuous and measuring errors will occur or the maximum measuring range may be limited. This is not app's fault.

This app also provides a light color temperature measurement in K (degrees Kelvin) that is only supported on devices employing color light sensor. On all other devices the display shows n/a (not available).

    I was able to use the light meter to get my boss to improve my work lighting. Thank you so much!

    This is a great app.detects light and operates just fine.I had built a simple meter myself using a voltage meter and photocell to pick up light variations.same thing's sees light and measures intensity.I want to try infrared.
