I can't think what I can use these for
I foolishly assumed that these photosensors were normally open, i.e. they would complete a circuit when there was no light, but they close the circuit when they "see" light. My fault, but I can't think what I can do with them. I was hoping to use them to switch on an LED when it went dark.

They work nicely
Good value and effective.Small in size but neat and functional.

Quality LDRs
I used these in a compressor foot pedal from PedaPCB and they work perfectly. Thanks.

NOT GL5516s
These are not GL5516s. I tested dark resistance on every one and had only 2 that were less than 2M; one that was 25k and one that was broke. Some had readings >10M.

Dark Resistance and Size
It was not clear from the seller what resistance these items were, nor their actual size, so I was pleased that they were exactly what I wanted, about 20kOhm when dark and 4 mm in width.
