Photone - Grow Light Meter app analytics for December 2

Take the guesswork out of plant lighting with Photone, the most accurate plant light meter app. Measure PAR, PPFD, DLI, lux, foot-candles, and color temperature (kelvin) directly with your phone or tablet. To measure light with research-grade accuracy, Photone uses the most precise sensor in your device: the camera**. Its unique measurement algorithm works directly with the RAW camera sensor data to capture true light intensity. This allows Photone to rival professional handheld PAR meters in accuracy and go even further by helping you interpret the numbers with in-app guides, tools, and additional features. MEASUREMENTS ⎷ Photosynthetically Active Radiation (PAR) as PPFD in µmol/m²/s ⎷ Daily Light Integral (DLI) in mol/m²/d ⎷ Illuminance in lux or foot-candles ⎷ Light color temperature in kelvin ⎷ Extended PAR (ePAR) including far-red light (ePPFD, eDLI) * FEATURES ⎷ Industry-leading accuracy, comparable to professional PAR quantum sensors ⎷ Pre-calibrated for your specific device ** ⎷ No ads ⎷ In-app guides ⎷ Light source selection for every type of grow light (LED, HPS, CMH, etc.) * ⎷ Average and peak readings * ⎷ Plant light calculator ⎷ Hands-free “read aloud” function * ⎷ Special underwater measurement mode * ⎷ Custom calibration option to align readings to another meter ⎷ Premium support for advanced grow questions * * These features require an in-app purchase to fully unlock DIFFUSER REQUIRED Like every real light meter, Photone requires a diffuser to measure accurately**. A diffuser scatters incoming light evenly on the sensor and prevents hotspots. While it may sound complex, the solution is surprisingly easy. You have two options: 1) Easily build a diffuser yourself in less than a minute using standard printer paper. This is accurate enough for most use cases. 2) Get the dedicated Diffuser Accessory (free worldwide shipping) for best accuracy and convenience. More details on https://lightray.io/diffuser/. ** ENHANCED LIGHT MEASUREMENTS WITH THE CAMERA Accurate light measurements with the camera require a default calibration, which is made available only for selected higher-quality devices. Check the full list of supported devices here: https://lightray.io/diffuser/compatibility/ On devices without default calibration, Photone automatically falls back to the built-in ambient light sensor (ALS). While the ALS works without an external diffuser, it is far less accurate than camera-based measurements.
