#190217 - optical sensor
I have been checking, by now, probably 25 different datasheets and not found what I am looking for.

Basically I am looking for a photo cell/diode/sensor/... that does not cost a fortune where the specs are such that you can make e.g. a unit that triggers at 47lm +-, say 2% without having to calibrate every individual unit.

any suggestions?
