Quick Answer: Do you need a special photocell for LED lights?

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?

Do you need a special light switch for LED bulbs?

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.

Why does my dusk to dawn LED light keep going on and off?

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. … With the light off, they cool down and shrink, remaking the connection so the light turns on again.

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.

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.

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.

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!

What happens if you use non dimming LED bulbs on dimmer switches?

Dimming LED lamps can save energy and changes the visual appearance and mood of your space. You can use a dimmable LED lamp in a non-dimmable circuit. You should NOT use a non-dimmable lamp in a dimmable circuit as it may cause damage to the lamp and or circuit.

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 happens if you put a non dimmable LED bulb in a dimmer?

If you install a non-dimming LED bulb in a circuit with a dimming switch, it will likely operate normally if the dimmer is at its 100% or fully on. Dimming the bulb, will likely cause erratic behavior such as flickering or buzzing and ultimately may cause damage to the bulb.

Can LED bulbs be used upside down?

It is possible to install LED headlights upside down, but this will make them dangerous – as they might blind other drivers or have misaligned beams. Ensure the diodes are horizontal and the shield, if the bulb has one, is at the bottom.
