LED & 'Blue light'. The health concerns.

Typical LEDs used in driving lights are short wavelength (blue light) and in configurations of extreme high intensity (HEV). The concerns of 'blue light' in (AMD) acute macular degeneration is increasingly a hot topic in the field of optometry. Dr. Shelby Temple, Phd, a visual neuro scientist shares his insights about BLUE LIGHT. The information discussed is very much in the public interest and could be a fore warning of what is to come.

Dr. Shelby Temple, a visual neuro scientist, explains 'WHY' BLUE LIGHT sources are a legitimate concern re your health. This applies for direct and indirect light. Consider the intensity of driving lights with brands and media forever hyping ever increasing outputs seemingly unaware or unwilling to acknowledge this evidence.

Follow the RELEVANT research re 'blue light'.

FYRLYT encourages people to follow the ever increasing independent research re 'blue light' in HIGH OUTPUT devices. Be aware the research re smart phones, tablets and domestic devices can potentially mislead you. Why? The LIGHT INTENSITY in these devices is typically quoted 0.6-2.1 lux and by many considered to be safe, not withstanding the effects re impacts on circadian rhythms and caveats Dr Temple states. LED driving lights at 50 metres, range between 254 and 888 times this level. This is not just about direct light of oncoming vehicles but your own forward projected light. With any 'expert' research always consider if there is any potential commercial bias re funding it or other profit driven agendas. We have seen one Australian local council report that avoids this evidence. The university report was 'funded' by the LED light contractor to the council for infrastructure projects. We find this very concerning.

The AMA & ANSES 'blue light' reports.

The A.M.A., American Medical Association report was published in 2016, ANSES, first published in 2010 and recently followed up in 2019 reaffirming their original position. ANSES is the Agency for Food, Environmental and Occupational Health and Safety reporting to the French government. AMA REPORT HERE. The ANSES REPORT (pdf) HERE.

Truck Drivers / High Usage / OHS.

For truck drivers it is obvious the importance of effective safe lighting for driving at night. The properties and performance of auxiliary driving lights when switched to high beam are vital to consider re driver safety and other road users. What are the long term consequences? What are these choices imposing on employed drivers or owners and their potential liabilities?

Driving light performance? Risk mitigation.

Let us focus on the basic considerations re driving light performance regardless of vehicle type. We assume the light that has relevant distance and volume. 1: Does the light resolve enough detail to minimise response time? 2: Does the light create glare or distraction resulting in eye discomfort? 3: Does the light cause undue fatigue? 4: Is there any immediate or potential long term residual damage caused by the light source?

Research consideration & conclusion.

FYRLYT acknowledges that there are currently no human trials proving LED driving lights cause harm. However, independent authorities have raised concerns about the potential harm of extremely bright blue-rich light sources. Preliminary research suggests that such sources could be harmful with substantial exposure. While most of the debate has focused on smart devices, it is important to note that high-performance driving lights can exceed the luminous intensity of a smart device by over 800 times. Before committing to super bright blue-rich high-intensity light sources, consider looking at research beyond smart devices, such as the information shared by Dr. Shelby Temple.
