Luxi iPhone Light Meter Tested

Author: John Honovich, Published on Oct 04, 2013

Adding a free app to your smartphone to measure light levels sounds great but our recent test showed how poorly they performed. However, a new iPhone accessory, Luxi, claims to deliver far more accurate results at a fraction of the cost (online for $29.95 USD) of professional lux meters ($100+).

Here's what it looks like attached to an iPhone:

In this report, we:

  • Test Luxi's performance at default and calibrated levels against a professional Extech light meter, which acted as our baseline.
  • Compare lux measurements in a variety of scenes.
  • Offer feedback on usability and the importance of calibration.
