The simple answer is no. LED lights do not cause cancer. While several studies have explored the cancer-causing effects of LED lights, there are no concrete linkages between LED lights and cancer. However, there are some concerns about the blue light emitted by LED lights and its potential effects on our health.

In any case, it’s always a good idea to be sure about potential health hazards!

In this blog post, we’ll delve into the current research on LED lights and cancer and find answers to the mystery of LED lights and their link to cancer. So, be prepared to question everything you thought you knew about LED lights and their potential risks to our health.”

Can LED Lights Cause Cancer?

Research has found that LED strip lights (of any kind) do not pose a significant cancer risk. LED lights do not contain harmful substances such as mercury and do not emit ultraviolet (UV) or infrared radiation. UV and infrared radiation are types of electromagnetic radiation linked to the development of skin cancer and other types of cancer. This adds weight to the fact that LED lights do not lead to cancer.

Relationship between LED lights and Cancer

To further support this assertion, let’s examine a scientific study on the relationship between LED lights and cancer.

There has been an instance where a Harvard study found that women who lived in neighborhoods with higher outdoor LED lighting were at a higher risk of developing breast cancer. An oncologist questioned this claim and declared that the study had no definitive evidence to establish such a link. This lends credibility to the fact that LED lights are not cancer-causing agents.

Can LED Strip Lights Cause Cancer?

No, LED strip lights or any residential LED light are not known to cause cancer. 

Your LED strip light consists of so many tiny LED bulbs. Like all other types of lights, these LED strips emit electromagnetic radiation in the form of visible light and a small amount of infrared and ultraviolet radiation. However, the radiation levels emitted by LED lights are not known to harm human health, including causing cancer.

Additionally, LED lights have been extensively studied, and no credible evidence has been found linking them to cancer. So, if you have been looking forward to having those bright LED light strips in your room, it’s time you got them!

Blue LED Lights & Their Health Implications

The only LED light you should be concerned about…

So, there is no evidence of any color light, including purple, yellow, green, or red LED lights causing cancer. But exposure to blue LED light can have certain negative impacts on health.

Circadian Rhythm Disruption

Blue LED light is known to suppress melanin production in the body. This not only disrupts the circadian rhythm (sleep cycle) but is also known to disrupt other bodily functions. The disturbances may occur in temperature regulation, blood pressure, and the secretion of digestive enzymes and hormones.

Retinal Damage

Optical radiation from the blue LED lights can harm the eyes — but only under certain conditions. Factors such as the spectrum and intensity of the light, duration of exposure, and the eye and viewing conditions must be taken into account. This means that while LED lights are considered safe, it’s essential to consider these factors to minimize potential risks.

However, it is important to note that these health implications are not as severe as causing cancer. Taking suitable precautionary measures can easily prevent these health concerns.

Do LED Lights Cause Radiation?

Concerns about LED lights emitting UV radiation are a thing of the past.

Traditional lights use a thin wire filament that produces UV rays in high amounts. Unlike these lighting solutions, LED lights use a semiconductor that only produces UV rays in quantity as small as equal to zero. Since the amount of UV rays emitted is so little, it causes no considerable health implications.

Today, LED lights are even more modernized and advanced. They are designed to minimize or even eliminate UV radiation, making them a safe and energy-efficient lighting option. As long as they are used as recommended, LED lights do not pose a significant cancer risk.

So… Is It Safe To Use LED Lighting?

Our thorough study of the scientific reports and research concludes that LED lights are safe to use in residential and commercial settings. As a matter of fact, high-quality LEDs are the safest lighting solution available today. They are more reliable, durable, and energy-efficient than any other lighting option, including fluorescent and incandescent bulbs.

Unlike traditional lights, these modern LEDs do not produce significant heat or emit harmful UV rays. They also don’t contain any harmful chemicals or materials that may cause burns and fires or strike a severe health concern. However, it’s always best to use LEDs with care and precautions; as with anything, neglect can lead to negative consequences.

How To Minimize Any Potential Health Risks From LED Lights?

LED lights causing cancer may be a myth, but using them carefully is only beneficial!

We have established that it is safe to use LED lighting, and they are not carcinogens. However, it is best to take all the necessary precautions to eliminate any risks related to your health. 

Here are 4 simple ways to keep yourself safe and healthy as you enjoy your LED-illuminated home:

1. Pick a High Color Rendering Index (CRI)

Choosing an LED light with a high color rendering index (CRI) is essential. The CRI measures how accurately a light source reproduces colors, with a higher CRI indicating more accurate color reproduction. LED lights with a high CRI are less likely to cause eye strain and fatigue.

2. Avoid Prolonged Exposure 

Can LED lights cause skin cancer? Nope. Does that mean you shouldn’t monitor your exposure to them? Again, nope!

Refrain from prolonged exposure to LED lights, especially at close distances. This is particularly recommended for blue-enriched LED lights. Studies have shown that blue LEDs disrupt your circadian rhythm (a natural internal process that regulates your sleep) and interfere with your sleep. 

Hence, to keep your sleep cycle undisturbed, it’s better to avoid using vibrant LED lights in the bedroom and limit exposure to them in the evening. During the daytime, make sure to keep a safe distance between yourself & the LED light source.

The recommended distance to maintain depends on the light’s intensity and the light source’s size. For example, it’s recommended to maintain a distance of at least 1 meter for a 100W LED light source, but that distance can be less if the light source is less intense.

3. Be Mindful of The Intensity of LED Lights

It is paramount to be aware of the intensity of LED lights. Bright LED lights can cause glare, which can strain the eyes and cause headaches. If you are experiencing these symptoms, try reducing the intensity of the lights or repositioning them to minimize glare.

To control the intensity of the light, consider dimmable LED lights. This will give you more power over the lighting in your environment and help you avoid exposure to overly bright lights.

4. Use LED Lights With Warm Color Temperatures

If you’re buying LEDs for your bedroom, consider buying an LED light with a warm color temperature (around 2700K).

LED lights under this color temperature can reduce your exposure to blue light, which can help minimize the risk of disruption to your sleep.
