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.
