App overview and purpose
Lux-525 Pro is an iPhone light-measuring application that delivers precise, easy-to-obtain readings without any extra hardware. The app is factory-calibrated against a professional light meter and uses a refined algorithm to produce consistent, real-time readings under a variety of conditions.
What it measures
- Luminous flux (total light output)
- Daily Light Integral (DLI)
- PPFD / PAR (photosynthetic photon flux density)
- Color temperature (CCT)
- Illuminance (lux)
Built-in tools and calculations
Lux-525 Pro includes an integrated calculator for converting and computing common lighting metrics:
- Lumens
- Foot-candles (Fc)
- Lux
- DLI
- PPFD
Source selection and accuracy
A comprehensive library of light source presets is provided to improve the accuracy of PPFD/PAR and DLI estimates for many lamp types. The app’s calibration and algorithm together aim to reduce systematic error, but results can vary with phone model and lighting conditions.
Exporting and saving data
You can save readings directly to your device or share them via SMS and email for easy logging and collaboration.
Limitations and intended use
This application is designed for personal and general-purpose use. While it gives highly accurate approximations, it is not a guaranteed substitute for industrial or laboratory-grade measurement instruments when absolute precision is required.
