LED Lights Dublin: Your Questions Answered

John Cook Electrical has been installing and upgrading homes with LED Lighting for years. We've all heard the advantages of LED lights, like how they are more energy efficient and last much longer than older incandescent bulbs. However, despite the proliferation of LED Lights, individuals still have questions about these bulbs. To make this information more accessible to our client base, we have compiled the most common questions and added comprehensive answers.

What are led lights?

LED lights, or Light-Emitting Diode lights, are lighting technology that utilises semiconductor diodes to produce light. LEDs are solid-state devices that convert electrical energy directly into light through electroluminescence.

Unlike traditional incandescent or fluorescent bulbs, which rely on heating a filament or passing electricity through a gas to produce light, LEDs generate light by moving electrons in a semiconductor material. When a current passes through the diode, electrons recombine with electron holes, releasing energy as photons. The colour of the light emitted depends on the materials used in the semiconductor.

LED lights have several advantages over traditional lighting technologies. They are highly energy-efficient, consuming significantly less electricity to produce the same amount of light. LEDs also have a longer lifespan, typically tens of thousands of hours, reducing bulb replacements' frequency. Additionally, they are more durable, compact, and environmentally friendly, as they don't contain hazardous substances like mercury.

LED lights are available in various shapes, sizes, and colours. They are commonly used in residential lighting, commercial lighting, automotive lighting, and in electronic devices such as televisions, smartphones, and computer screens. LED technology has seen widespread adoption due to its energy efficiency, versatility, and long-term cost savings.

How long do led lights last?

LED lights have a significantly longer lifespan than traditional lighting options, such as incandescent or fluorescent bulbs. On average, LED lights can last anywhere from 25,000 to 50,000 hours or even more, depending on the quality of the LED and its usage.

If LED light is used for an average of 8 hours per day, it could last around 8 to 17 years before reaching its end of life. However, it's important to note that LED lights don't suddenly stop working at the end of their lifespan. Instead, they gradually become less bright over time.

The lifespan of LED lights can also be influenced by various factors, such as the LED chip's quality, the lighting fixture's design, operating conditions (e.g., temperature), and usage patterns. Higher-quality LEDs and better heat management can contribute to longer lifespans.

It's worth mentioning that the lifespan of an LED light is often estimated based on the point where it reaches 70% of its initial lumen output. This means that even after the specified lifespan, the LED may continue to function with reduced brightness.

Overall, LED lights are known for their longevity, which translates to reduced maintenance costs and fewer bulb replacements over time.

Why do led lights flicker?

LED lights can flicker for various reasons, and understanding the causes can help address the issue. Here are some common factors that can lead to LED flickering:

  1. Incompatible dimmer switches: LED lights may flicker if connected to dimmer switches not explicitly designed for LED lighting. LED lights require dimmers that are compatible with their low-voltage and electronic drivers. Using an incompatible dimmer can result in flickering or inconsistent dimming.
  2. Voltage fluctuations: LED lights are sensitive to voltage changes. If the electrical supply to the LED lights is unstable, such as when there are voltage spikes or drops, it can cause flickering. This can occur due to issues with the electrical wiring or problems in the power grid.
  3. Inadequate power supply: If the LED lights are not receiving a stable and sufficient power supply, it can result in flickering. This can happen if the wiring is not properly installed or the power supply is overloaded.
  4. Incompatible LED drivers: LED lights often require drivers or ballasts to regulate the electrical current. If the LED driver is inconsistent with the LED lights or is of poor quality, it can cause flickering issues.
  5. Thermal issues: LEDs are temperature-sensitive, and excessive heat can affect performance. If LED lights are not adequately cooled, it can lead to thermal problems, causing flickering. This can happen if the LED lights are installed in enclosed fixtures that don't allow proper heat dissipation.
  6. Manufacturing defects: In some cases, LED lights may flicker due to manufacturing defects or poor quality control. This can include issues with the LED chips, solder joints, or other components.

How do I stop LED Flickering

To address LED flickering, you can try the following steps:

  • Ensure you are using dimmer switches specifically designed for LED lights.
  • Check for a stable and adequate power supply, addressing any electrical issues.
  • Use high-quality LED lights and drivers from reputable manufacturers.
  • Verify that the LED lights are adequately cooled and not installed in enclosed fixtures that restrict heat dissipation.

If the flickering issue persists or poses a safety concern, it's advisable to consult a qualified electrician or contact the manufacturer for further assistance.
