Flicker-free LED lighting

As the world switches to LED lighting, many believed that the days of flickering light bulbs were long gone. However, despite the issue of flickering bulbs being a lot less common, it definitely is still an issue.

So, why do some LED light bulbs flicker, and how can we solve it? Below, we look into this and also explore the flicker-free options available.

 

The different types of flickering

With lighting in general, there are two types of flickering - visible flickering and invisible flickering. They are both pretty self-explanatory. One you can see with your eyes, the others you cannot.

Visible flicker occurs when the light output changes rapidly. Typically, anything below a frequency of 100hz can be seen.

The invisible flicker is anything over 100hz. This is because most people can no longer distinguish between the individual flickers, as they are simply moving too fast. They’re definitely there - and can cause problems.

 

While LED lighting is much more advanced than traditional lighting, they still fall victim to the flicker problem. Both visible and invisible flickering can prove to be a problem for LED light bulb owners.

 

Why does it happen?

So, why does a light flicker in the first place? Knowing this can help us better understand our lightbulbs, and how we can improve them.

Let’s look at strobe lighting - a deliberate flicker of a bulb, to create a theatrical effect. This can make the brain view things in slow motion.

On the other hand, unintentional flickering can be traced back to our power companies. They design electricity to run to our bulbs using AC, rather than DC. This leaves us vulnerable to flickering and even a hum - you can hear this with flickering bulbs.

Are there health effects?

Flickering lights can be an annoyance, but they can also be seriously harmful.

Symptoms of an invisible flicker can include eyestrain, dizziness, headaches, impaired thought, migraines, and a generally sick feeling. This can be especially damaging for those working at home, or those with other medical conditions.

A visible flicker can cause these same issues. A visible flicker also proves to be especially dangerous for those with epilepsy.

 

How can we solve this?

One way to solve a flicker is by correcting the power. If you don’t do this, the power flow will always cause flickering. Basically, if the driver design of the LED bulb adheres to the stable DC current and the ample ripple suppression, there shouldn’t be a flicker.

Of course, we understand that this extremely confusing. While we’re always here to help and answer any questions, there is an alternative.

The simplest way that we can solve a flickering bulb is by obtaining a flicker-free LED bulb. Typically, these are bulbs with a higher frequency, which means that there is no visible flicker.

With this, there are no side effects - making them perfect for living in and working in.
