Why does my LED light bulb flicker?
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 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.
Do LED bulbs flicker before they burn out?
The traffic lights that ‘burn out’ are more often the power controllers / diode packs than the actual LEDs going dead. Flickering would be caused by the power controller, which would be built in to most consumer LEDs. Click to see full answer.
Are flickering LED lights dangerous?
Lights can flicker for a number of reasons, some of which are harmless and others hazardous. … Light dimmers with incompatible lightbulbs (such as LEDs) can flicker when they’re set on low. Fortunately, this is not a dangerous situation either, however annoying it may be.
Why are my LED bulbs failing?
Temperatures are too high (or too low)
LEDs shouldn’t be placed in tightly enclosed fixtures unless they’re approved for enclosed spaces. When heat can’t dissipate from the heat sink, it can cause lamps to fail prematurely. Also keep the surrounding environment in mind.
How do I stop my dimmable LED lights from flickering?
Summary – How to stop LEDs flickering
- Always drive LED products using an LED power supply that’s designed for the job. …
- Make sure all your LED products are compatible with the control circuits and power supply you’re using.
- Check for loose wiring and other faulty connections. …
- Consider using a constant-current LED driver.

What kind of dimmer switch do I need for LED lights?
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.
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 are flickering lights a sign of?
Flickering or blinking lights are usually caused by one of four things: Problem with the bulb (not in tight enough, wrong bulb type for dimmer switch) Loose light plug. Faulty light or fixture switch.
Why do my bulbs keep blowing?
A loose connection in the lamp holder can also cause the light bulbs to blow. When the circuit is not tightly completed, it makes the electricity jump and not flow. When the power jumps, it creates more heat in the fitting than recommended for by the bulb to handle forcing it to blow.
What causes low voltage LED lights to flicker?
Low voltage LED lamps require a stable and clean input voltage. … An unclean and fluctuating output voltage on the transformer can cause the LED lights to flicker. What to do? Old halogen transformers with fluctuating output voltage are inappropriate for LED lamps and must be replaced by an LED power supply.
