To do this turn the switch Off, then wait about 6 seconds, and then turn it back On. As the light comes on, it is too bright for the photocell which switches the light off. The main culprit causing a flicker using a socket auto dusk to dawn photocell is the using a regular looking rounded light bulb.
During the day when natural light is present, the LED dusk to dawn light with photocell will not activate which saves energy and during the lights , will turn on automatically to illuminate the place completely. To check a photocell , use a digital multimeter. Turn the multimeter on, and place it on the setting for resistance. Resistance is usually indicated by the Greek letter omega. If the multimeter is not auto-ranging, change the knob to a very high level, such as megaohms.
The technical reason behind the failure of the electromechanical photocells is mainly the fact it is a NC type of relay both magnetic and thermal , so it turns ON when the control circuit is not energized. Whether you choose a watt or watt Dusk to Dawn light fixture, the expected duration of the lamps is 50, hours. Dusk to Dawn light fixtures are virtually maintenance free and you don't have to worry about replacing the bulbs for nearly 10 years. When You 're Home at Night This is a good time to leave the porch light on.
It alerts burglars to your presence, particularly if indoor lights are on too. The porch light also acts as a spotlight on the front door. You can easily see who's approaching through either a window or peephole. Steps: Turn off the power at the main breaker switch. Remove the old light fixture and replace it with the new motion-sensor lights, connecting the white wire to white and the black wire to black with the wire nuts.
Tuck all the wires neatly into the socket. Points the bulbs and the sensor in the desired directions. In order to have more than one motion sensor or motion detector turn on the same group of lights it is necessary to wire the motion sensors in parallel with each other, in the same manner as the lights are wired. The only solution to bad bulbs is to replace them with new ones.
In such cases, the best way to fix a bad photocell is to simply replace it. Fluctuating Voltage If your dusk to dawn lights keep flickering on and off, or if the lights frequently burn out for no apparent reason, this could be a result of fluctuating voltage. Fluctuating voltage is often caused by corroded or loose connections.
For your safety, call an electrician to help you with the best solution to this issue. System Issues Your dusk to dawn light sensor may not be working because of system issues or overrides. Thankfully, system issues concerning dusk to dawn lights are the easiest to fix. Simply reset the lights by turning them on and off. These methods can help you out! If this is the case, open the bulb and wipe away the dirt obstructing the sensors.
I know, this can be hard sometimes! Fix Loose or Faulty Wiring Loose or damaged wiring can cause a myriad of electrical issues, including faulty sensors. Search forums. Log in. Install the app. For a better experience, please enable JavaScript in your browser before proceeding.

Thread starter nottick Start date Jan 6, Messages 21 Reaction score 0 Points 0. The switch has three wires, red black and white. It has to service two seperate light fixtures.
I have tied the feed to the red, tied all black wires together to the black wire from the switch, all whites together to the white from the switch. However, the switch only works for one fixture, the other remains constantly on.
What am I missing? You say the switch has three wires? Are you calling the sensor the switch? Typically a sensor has to have the line tied to the black wire of the sensor and the lights black wires to the red. Also you said you had the white wire to the switch,are you talking about a switch leg where you have a white go to the switch from the power or line side and a black go back to the light? By the way if this is the case the white should be reidentified black.
Wiring is not always color to color. One reason it can be very hard and dangerous for a DYI. Messages Reaction score 0 Points 0. Dusk til dawn switch sensor I understand that - Red - to black wire of fixtures.
Did this ,but one remains on all thevtime. Well you are going to have to provide more info if you can't follow the circuit. Click to expand I am not an electrician. I could find no instructions when I was hooking up mine so I experimented. It worked so I hooked up several for friends the same way that is on my instructable. Sorry I cannot help. Black feed from house to black on photo eye,red from eye to black of lite,then all three whites together.
The light switch should always remain in the on position for the photocell to operate automatically. Turn the light switch off first to make sure the lights do in fact turn off to isolate the problem to the wiring at the photocell or the photocell itself. If the lights remain on with the switch off Highly doubtful you have something messed up.
With the light switch on you need to test the photo-eyes circuit. This type of photo-eye has electronics in it that increase the resistance and stop the flow of electricity when light hits the sensor. Take a bright flashlight, laser etc and shine it directly on the face of the photo-eye for a short time and the lights should go out. If they don't go out you have a defective photoeye. If they do go out then the photo-eye is in a position where it isn't receiving enough daylight to increase the internal resistance to shut off the current flow thru the photo-eye thus turning off the lights.
WIth the photo-eye removed from the circuit, and if you have a ohm meter, you can test the ohms thru the black and red wire coming out of the photoeye. When you shine light in the face of the photo-eye you should see a increase in resistance and when you cover up the photo-eye the resistance should drop to close to zero allowing current to pass. Hi BillR Your diagnosis is very good. On normal sunny days, it turns the bulb off as it should.
Reply 4 years ago. That is always a real possibility and most likely the problem. I went on the assumption it was wired correctly because it is pretty straight forward, but then again you never know for sure If it's staying on all the time then something's done up wrong.
It could just be some sensors turn on for a few mins when initially powered up before turning off and waiting for the light level to drop enough to turn on. I had a photocell on my exterior Christmas lights and if the cell was facing into the ground It would turn on much sooner then when I turned it to face away from the ground or wall.
So many variables that he really needs to eliminate each problem and making sure its wired properly would be my first step and then covering the sensor with tape or shinning a light into it to determine if the sensor is actually working.
