Photone - Grow Light Meter

The PAR meter in your pocket! The Photone (previously named Korona) app allows to effectively and accurately measure your grow lights' illuminance in Lux or fc and PAR / PPFD in µmol/m2/s or as DLI with industrial grade accuracy.

Tests with various grow lights prove that Photone repeatedly reaches the best-in-class light measurement accuracy with error rates down to less than a few percent against a $500 professional light meter.
