Common LED light problems and solutions

Common LED light problems: The LED lamps are a new revolution in the electronics world. LED lamps are replacing other conventional lamps everywhere in our houses, offices society public places etc. LEDs are having more efficiency and long lifespan. There are significant performance advantages for LEDs, but these have also some technical problems. We are going to discuss some common LED light problems like flickering, buzzing or not dimming properly. Flickering is less present in LED lamps compared to conventional lamps but still, it is still a factor. We are discussing the possible causes of the common LED light problems and solutions for this.

 LED light Flickering:

We can observe two types of flickering with LED lights – visible and invisible flicker. Obviously, only visible flicker can be observed with naked eyes. This is the result of a rapid change of output from a given source. It is observed that anything below a frequency of 100Hz is visible. Invisible flicker is the flicker that is present but we cannot see.

Reason:

Setting up the wrong dimmer: Dimming of a LED lamp saves energy and changes the visual ambiance of your space. Using wrong dimmer switch can cause flickering and buzzing of LED light. Our home is likely to have an old style dimmer which is used for dimming light with a range between 200W to 1,000W. So here the problem is for LEDs don’t need anything like that higher level of current in the circuit.

High-powered appliance in the same circuit: Turning on High power appliances in the same circuit can cause a momentary voltage surge in the circuit. This can cause flickering.

Loose connections: This also is the common causes of flickering.

Solutions:

• Make sure you purchase the correct dimmable or non-dimmable LED for your type of circuit
• Get right dimmer switch designed for LEDs; use specific LED dimmers.
• Do not mix LEDs and old-style (incandescent, halogen or CFL) bulbs in the same fitting.
• Also, we can use a dimmable LED lamp in a non-dimmable circuit but we should not use a non-dimmable lamp in a dimmable circuit. This may cause damage to the lamp.
• We need to get our circuit checked by an electrician to examine if the flickering is caused by high powered appliances or loose connection and get it rectified.

Lights glowing, even when switched off:

Some light switches allow a very small amount of electricity, even when it is switched off. For other conventional bulbs, this is not possible because the power was never enough for the light. LED bulbs use very low power and a small ‘leak’ of electricity can be enough to make the light glow.

This problem may be with an electrical circuit, or very poorly manufactured LED bulbs.

Other LED bulb problems:

Narrow beam angle – May cause dark patches in the room

Inconsistent light output – bulbs of varying color or brightness may cause a patchy light effect

Sudden rather than gradual dimming of light – creating a less smooth effect

Solutions: The best way to avoid such problems is to opt for high-quality bulbs. We should avoid mixing LEDs with old-style (incandescent, halogen or CFL) bulbs in the same fitting. We need to use identical LED bulbs (same brand /spec) in one fitting for consistency.
