Flicker-Free vs Non-Flicker-Free LED Panel Lights

In recent years, LED lighting has gained popularity for its energy efficiency and durability. However, one aspect that is often overlooked is flickering in panel lights. In this article, we will delve into the topic of flickering lights and the significance of using flicker-free LED lights for a more comfortable and healthier lighting experience.

What is Flickering in Panel Lights?

Flickering refers to the rapid and repeated variation in light output, often perceived as a subtle pulsation or flicker of light. While it may seem unnoticeable to some, prolonged exposure to flickering lights can lead to eye strain, headaches, and even fatigue. 

Panel lights are known for their uniform illumination, making flickering even more apparent and bothersome for this type of LED light.

Causes of Flickering

Flickering in panel lights can be caused by various factors, including improper wiring, incompatible dimmer switches, or the quality of LED drivers. 

Inadequate power supply or electrical interference can also contribute to the problem. Identifying the root cause is essential for finding an effective solution for flickering. 

Measuring Flickering in LED Lights

LED lights exhibit flicker through quick variations in brightness. This variation's intensity is quantified using a metric known as per cent flicker. To determine per cent flicker, the disparity between the highest and lowest brightness levels during one cycle of flicker is measured. 

A light source with a 0% flicker value means it has no flicker, while a 100% flicker indicates complete fluctuation between being fully on and off. Typically, a light source with a flicker rate below 5% is considered effective in minimising flicker impacts.

Non-Flicker-Free LED Lights

Non-flicker-free LED lights, also known as flickering LED lights, are those that exhibit noticeable flickering or pulsation. They can cause discomfort and potentially lead to adverse health effects for those exposed to them over prolonged periods.

Flicker-Free LED Lights

Flicker-free LED lights are specifically designed to minimise or eliminate flickering, ensuring a more consistent and stable light output. These lights use advanced technology, such as quality LED drivers and effective power management systems, to reduce flickering to imperceptible levels.

Advantages of Flicker-Free LED Lights

• Reduced Eye Strain: Flicker-free LED lights provide a steady and uniform light output, reducing eye strain and fatigue, particularly in environments where lighting is used for extended periods.
• Better Visual Comfort: Flicker-free lights create a more pleasant and comfortable lighting environment, making them suitable for schools, offices, and other settings where visual comfort is essential.
• Improved Productivity: By minimising flickering, these lights contribute to improved concentration and productivity in workspaces, helping individuals stay focused and alert.

Choosing Flicker-Free LED Lights

When selecting LED lights, it's important to choose flicker-free options to ensure a high-quality lighting experience. Consider the following factors:

• Look for flicker-free certifications or standards, such as "Flicker-Free Certified" or compliance with industry guidelines, to ensure the lights meet the required specifications.
• Check product reviews and ratings to gauge overall customer satisfaction with regard to flickering issues.
• Consult with reliable lighting experts or suppliers who can provide information on the flicker-free characteristics of their products.

Conclusion

Choosing the right lighting is important for both visual comfort and overall well-being. Flicker-free LED panel lights offer numerous advantages over non-flicker-free options, providing a steady and comfortable lighting experience. By opting for flicker-free LED lights, you can create a visually pleasing and healthier environment for yourself and others.
