3 Reasons WHY FYRLYT is superior. How FYRLYT delivers more detail & less glare than any LED or HID.

Buying driving lights in 2019 can be very confusing. The majority of 'expert' opinion and salespeople will insist LED or HID is the best choice. FYRLYT proposes differently. Why? 3 fundamentals of science.

 

The function of driving lights and adaptive night vision is very specific and widely misunderstood, none more so than the majority of marketing written around it. Brands promoting 'BRIGHT WHITE LIKE DAYLIGHT 5000K' as being ideal should be treated with caution. Often with this marketing spin will be 'LAB' extrapolated data re 1 LUX distances or worse still 1/4 lux just to attain what appears a long distance measurement designed to do no more than 'impress' a 'newbie'.

FYRLYT from 2011 has made a stand against this nonsense and the brands and media that continue to perpetuate this 'hype'.

No LED or HID used in driving lights can refute the following 3 statements of claim. FYRLYT challenges any person or brand denying this to provide empirical evidence for a FACT based discussion.

 

Hold the salesperson, media guru or brand to account and listen to what they say.

We welcome any discussion direct with no obligation. FYRLYT is here to assist you make the best choice for your night driving needs.

#01 - C.R.I. Colour Rendering Index - 42% more than typical LED or HID

FYRLYT has the most complete colour spectrum in the high performance driving light market!

 

FYRLYT delivers light with a 100 COLOUR RENDERING INDEX, this is the maximum value possible for colour rendering. Our light source by definition is a black body emitter which is the yardstick by which colour rendering “CRI” is measured.


Why is good quality colour rendering (CRI) important in a driving light?  

 

We only see the colours that are reflected to our eyes, if a light source is deficient in a colour we don’t see the colours true to life… We rely heavily on colours to detect and differentiate risks at distance… The size shape and silhouette of an object is defined by its subtle differences in colour in the outback. As a result accurate colour rendering becomes crucial in detecting an animal when the animal and the background are similar in colour.

#02 - ACUITY

FYRLYT's Superior Visual Acuity

 

MYTH: 5000 to 6000 Kelvin lights are the nearest to daylight and are therefore best for seeing at night.

 

FACT: Lights biased towards the longer wave lengths, 3000 Kelvin have less glare and better visual acuity. Blue biased lights actually have higher discomfort glare and result in poorer visual acuity.

 

The American Medical Association (AMA) 
“Encourages the use of 3000K or lower lighting for outdoor installations such as roadways.”

The University of Michigan Transportation Research Institute Ann Arbor, Michigan 48109-2150 U.S.A.
“Ratings of Discomfort Glare” In this study, we investigated whether an observer’s subjective judgment of discomfort glare is different for each type of light source at comparable levels of photopic illuminance. In previous research examining the influence of wavelength on glare ratings, middle wavelengths (yellow, 577 nm) produced the least discomfort, while short wavelengths (blue, 480 nm) produced the greatest discomfort (Flannagan et al., 1994).”


Why does FYRLYT have superior visual acuity?

 

FYRLYT has most of its light output biased in the longer wavelengths of light by comparison to HID or LED's which have a blue bias… Blue light waves are the amongst the shortest, highest energy wavelengths in the visible light spectrum. Because they are shorter, these "Blue" or High Energy Visible (HEV) wavelengths flicker more easily than longer wavelengths. This kind of flickering creates glare that reduces visual contrast and affects sharpness and clarity. Short wavelength light “Blue biased light” is simply bad for Glare… “Long wavelength” ( Red/Yellow biased) is superior.

#03 - TYNDALL

FYRLYT has a greater ability to penetrate moisture, dust and smoke. “The Tyndall Effect”.

 

Blue and blue biased light is scattered more strongly than red light by the Tyndall effect.

The Tyndall effect, also known as Willis–Tyndall scattering, is light scattering by particles in a colloid or in a very fine suspension. It is named after the 19th-century physicist John Tyndall.

The amount of scattering depends on the frequency of the light and density and size of the particles. As with Rayleigh scattering, blue light is scattered more strongly than red light by this effect. This is indeed why the sky is blue... On a clear day the sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight, the blue light is simply unable to penetrate as strongly.

In short blue biased light like led and HID is poor at penetrating air born particulates and long wave length light Red/yellow is good and it is not by a trivial amount… The intensity of the scattered light depends on inverse of the fourth power of the frequency.


Why is having a light source that can penetrate air born particulate matter important?

We rarely drive in the outback in clear air conditions and this is when we need good lighting the most.  Short wavelength biased lights can be rendered relatively ineffective and a distraction with modest amounts of dust, moisture or smoke.

 

FYRLYT is long wavelength biased and will penetrate airborne particulate matter such as dust, moisture or smoke far better than a blue/green biased light like a led or hid.
