It has been shown that sunlight and artificial light falling on glass pH electrodes can cause a decrease in measured pH values.
This decrease does not appear to be due to any photo effect on the silver-silver chloride half-cell within the electrode, and is, therefore, attributed to increased conductivity of the glass membrane, possibly arising from the formation of F centres.
