Standard photocells require a small current to operate during the daytime when the light is off. Because LEDs run at such a low voltage, this small current causes interference, flickering, and premature degradation. Therefore, LEDs require a different type of photocell than conventional bulbs.
Can photocells be used with LEDs?
Though I have only one data point, it appears that LEDs are not recommended for fixtures with photocells because the current constantly flows through the bulbs. This is because the photocell requires a little bit of energy to determine when it is daylight and when it is night.
Can you add a photocell to any light?
The Photocell is really simple to install, it only has two black wires and it basically needs to be tapped into the black wire that is already running to your light fixture from your house. 4. … Connect one photocell wire to the black wire coming from your house and twist the exposed copper wire together tightly.
Do you need a special switch for LED lights?
Because of their circuitry, LEDs are not always compatible with traditional dimming switches. In some cases, the switch must be replaced. Other times, you’ll pay a little more for a compatible LED.
Can one photocell control multiple lights?
One photocell can control multiple luminaires assuming they are on the same line, just like a manual switch can turn on and off multiple luminaires. … If the power is on at the first switch, the photocell will control the power out of the electrical box.
What causes an LED light to strobe?
It could be a number of things. But most commonly, LED bulbs may flicker or dim in your home when there are voltage fluctuations in your home’s wiring. When electrical loads turn on and off in your home, this creates a change in voltage levels, which may cause the LED lights to occasionally dim or flicker.
Where should photocells be placed?
For most general applications the photocell should be mounted between 6-8 feet of the window area, central to the area illuminated by the electrical lighting that will be controlled. In all cases the photocell must be mounted so that it looks at reflected light only and not at any direct light.
Do photocells wear out?
Photocells are sensors that allow you to detect light. They are small, inexpensive, low-power, easy to use and don’t wear out. For that reason they often appear in toys, gadgets and appliances.
Does a photocell need a neutral?
The photocell needs the neutral to operate it’s internal switching.
Can you make any outdoor light dusk to dawn?
Well, I have great news: You can easily convert any standard light fixture into a dusk-to-dawn light yourself by simply replacing the bulb. Yes, you read that right. Just replace the bulb!
Can LED lights cause a fire?
LED lights do not emit light from a vacuum as most other bulb types do. … Overheating is one of the reasons a bulb could start a fire, but that is highly unlikely to happen with LED lights. They may feel hot to touch, but they produce light at a significantly lower temperature than other bulbs.
What is the best dimmer switch for LED lights?

Can I use regular Dimmer for LED lights?
Check Your Existing Dimmer
The type of dimmer switch and it’s minimum/maximum load range will indicate the compatibility with LED light bulbs. Trailing edge dimmers work best with LED light bulbs and leading-edge dimmers work best with traditional incandescent and halogen light bulbs.
How do I know if I have a photocell?
The easiest way to determine how your photocell works is to connect a multimeter in resistance-measurement mode to the two leads and see how the resistance changes when shading the sensor with your hand, turning off lights, etc.
Why does my led dusk to dawn light flicker?
The flickering on LED is caused by a loop of rapid on/off actions by the photocell. 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.
How do you test a 3 wire photocell?
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.
