You can try to add some resistors (100 - 700 Ohms or variable resistor/potentiometer) in series with cathode or anode to make resistance of whole circuit bigger and have more stable parameters. With ...

This library (with examples) is designed to be integrated in projects using any kind of photocell to retrieve the light intensity (in Lux or footcandles). It handles the GL55xx photocell series but ...
