2 Pack AC DC 12V 10A Auto On/Off Photocell Light Switch Photocell Photo Switch Photoelectric Control Light Sensor Switch Dusk to Dawn Photocell Sensor for Outdoor Lighting Fixtures

Dusk to dawn the switch is off to a great start. It’s part of a 12V system at my chicken coop responsible for turning lights on and off. The wiring is straight forward and the pigtails were sufficiently long. The switch is mounted outside on the back of the coop so time will tell how well it holds up in the weather.

I placed this inline for my outdoor LED strip light. I do not have to remember turning this off during the day and on during the night. It worked well and looked to have durable materials. I will buy this again.

I've read a number of reviews on here saying it doesn't work with DC. It absolutely does. You just have to connect to the correct wires. Positive goes to the black wire, and negative goes to the white wire. Red is the output. I'm using this to operate some yard lights off of a solar panel battery system and it works great! Would highly recommend these for any 12v project where dusk to dawn operation is desired. My Solar Battery puts out about 12.6 to 12.8 volts at night, 13.8 volts during sunlight hours and have had no issues, so I'll say there is some voltage tolerance in the units.

They appear to be as described. I would prefer a more robust feel in the hand. They have a slight delicate "feel". However, if remain functional for a reasonable period of time, that's what counts. The instructions, wiring (versus other here) - are correct. In a low voltage scenario light activated switch like this - neither side would care if power or load and instead of have two "Neutral" wire (that would be connected anyway internally - they supply the one for both power/load. The white "shade" should hang down since has a condensation drain hole (1mm +-) and assume the "top" is water "proof". To "Test" it, I wrapped a dark piece of cloth around it, in hand and that was enough - 5 secs consistently to turn "on" and 4 secs to turn "off". So far it is working as expected the past 3 days. The fact that they send two does not instill "confidence" in the quality or durability - but, who knows - time will tell. I installed it in a somewhat shielded spot, not hammered by rain, snow, etc - light exposure is fine/optimal. I hope that helps someone.

Second time purchase as this product is an inexpensive way to salvage a low-voltage transformer with a built-in but defective dawn-to-dusk sensor.

To be used to control my solar lights.

Easy to install per instructions. Black to Load Terminal of Transformer, Red to the Load (lights) and White to both the Transformer Common and Load (lights) Common. One note, the photocell is rated at 10 Amps. So if your Transformer Output is 12 Volts your maximum Load is 120 Watts. P=I V Where P=Power, I=Amps and V=Volts.

Didn’t work for my application wired exactly how it said red wire going to light positive black wire going to 9v battery positive white wire to light negative and white wire. Waited till dark nothing coming out of load side but had 9v going in line side just doesn’t work for my application I guess
