THE perception has always been that driving lights need to throw light as far down the road as they can, to be of most benefit to the driver.
In order to gain this sought-after distance effectively, light is concentrated and contained to a single pencil beam, which, as a result, sacrifices the spread of light.
The recent introduction of LED technology to driving lights has brought with it new observations.
Effective light is one such observation, and can simply be described as useful light.
A single beam of light focused onto one spot 1km down the road may sound impressive, but in reality, there's less effective light output for the crucial 300-400m ahead of the vehicle. An additional spread beam is often introduced to compensate for this lack of effective light.
Driving by candlelight: At one lux (the same brightness as a single candle) at 1km, the average person would struggle to identify anything.
When you consider that even a fully loaded (64 tonne) B-double at 100kmh requires 127.1m breaking distance to pull up, it's that immediate 300-400m that is most relevant for the driver.
The kangaroo 1km down the road, can hop away well before it's a hindrance to the driver. But the kangaroo 200m from the vehicle could easily hop into the path of that vehicle, necessitating the driver's quick response to a potentially fatal obstacle.
Peripheral vision: THE colour spectrum of LED is closer to that of sunlight, which serves to help reduce eye strain. Great Whites spread a crisp light ahead of the vehicle, enabling excellent peripheral vision, which is important to detect pedestrians and other potential hazards.
Research shows peripheral vision and detection are enhanced under white light. This white light (as opposed to more yellow light produced by halogens) allows faster peripheral detection and therefore the opportunity for a faster reaction time by the driver.
Great Whites driving light features: IP68 rated, waterproof up to three metres; shock proof and vibration dampened rated up to 10G; 50,000+ hours; LED lifespan: five-year warranty; integrated Electronic Thermal Management to regulate heat levels to prolong the life span of the LED by engaging Pulse Width Modulation; integrated circuitry flashes the LED faster than the human eye can see for reduced heat and prolonged LED life; channelled heat sink designed for superior heat dissipation to prolong the life span of the LED; polycarbonate lens; extruded 6061 aluminium housing for ultimate durability and protection; includes environmentally-sealed Deutsch connectors; can be mounted vertically, horizontally, diagonally or at any angle; latest LED technology (old technology requires the fitment of a separate spread and separate pencil beam light for output, to provide both span and distance); the Great Whites' cutting edge LED technology delivers both distance and spread of light in every individual LED.
Gone are the days of mismatched driving lights.
