@did1947 you never want to break the white wire connection with any kind of switch. A switch should cut power TO the load (light, appliance) NOT FROM. If the switch is on the white wire, A man touching a light or appliance he has turned off could become the white wire himself. I have experienced this joy.

This is also the trouble with using a 120 switch on a 220 line. The
danger still remains because the apparent "off" has only broken one line
so the other 120 side still is suplying power. A switch should cut off
ALL power to the load.

Just wire as shown above and it will work.

Important not: The many a photocell has a delay built into it. I noticed mine still had my light turn on when I flipped the switch in bright daylight. roughly 1 minute later it turned off. Covering the cell, I felt it click 30 seconds later and the light turned back on. My guess this feature prevents rapid cycling on setups with light feedback.

Photocells are simply resistors that have a light-dependent resistance. Photo-sensitive plates are mounted on the front of the resistor, and as more or less light hits these plates, the resistance value of the photocell changes.

In my country we don't use white, what comes out of the house is either black or blue for neutral, and red or brown for live. Recently when i bought a photocell sensor i used your 3rd diagram but i had to connect the red wire from the house to black wire on the sensor and white from the sensor to black from the house. The red wire from the sensor was connected to the load and the system worked perfectly. I found your diagram very useful, thanx.

Sorry, but to continue, I used the photo control just like a light switch with the photo control wired between the light white wires. I did not use the black wire at all, in fact I wire nutted it off. Will this work?

Thank you, Dan

As the resistance changes, the current in the circuit also changes, since resistors affect current in electric circuits. Current determines the brightness of a light.

Yes, you can use on any lamp, just remember that you need a light source during the day so the lamp can shut off.

Sorry for the delay on answering, I had some big issues in trying to post anything to these.

Thanks
