Spot Check: Before you call it a day, fire up those lights and make sure the photocell''s working like a charm. The lights should take a nap when they sense natural light.
How Photocells Work. A photocell works by changing its resistance based on the amount of light it receives. In the dark, the resistance is high, and as light intensity increases, the resistance decreases. The resistance can be measured using a multimeter or by connecting the photocell to a circuit and measuring the voltage across it.
To test the photocell, turn the power back on at the breaker. Make sure that the light switch is in the on position. Cover the photocell with your hand—if the light turns on when the photocell is covered, your photocell is working properly. Finish installing the photocell by putting your light fixture back together.

It''s simple. Try to cover the photocell and prevent light from hitting it. When you do this, a functional photocell should read ''0''. Next, remove the cover and flash a light unto its surface. A functional photocell should read about "1020." If the photocells don''t read correctly, it could be because the wires are shorted.
To test the photocell, turn the power back on at the breaker. Make sure that the light switch is in the on position. Cover the photocell with your hand—if the light turns on when the photocell is covered, your photocell is working properly. …
This can lead to a photocell either not working at all or having spells of inactivity followed by spells of proper functioning.

A photocell is made up of a semiconductor, the working of which is dependent on the intensity of incident light. When the amount of light exceeds a certain frequency, the electrons of the semiconductor are delocalized or "freed," and a photocell starts conducting. When the light is less, no electrons are freed, and the photocell doesn''t conduct.
