So what does Lux Soap have to do with off-road lighting? Not much at all really!
Candela, Lux and Lumens all refer to varying terms of light output from Manufacturers. Candela was originally used by many Manufacturers including KC Hilites to describe the amount of light available via the light source - usually Halogen, but with newer technology such as HID and LED the term Candela, is rarely used. Lumens better describes light output and gives us our ability to see down the road.
Here we let you know what's what!
Lux - Lux is the measure of light at a specific distance within an area at that distance, KC measure Lux at 10 metres and a square metre at the 10 metre range. The further you go away from this point either left or right, the light source decreases.
Candela - Candela is the total volume of light available from the light source at a specific angle and direction away from the source. A wax candle provides the light value of 1 candela. If we had a 25 Watt Globe, we may have brightness of approx. 140 candela in an open area, if we harnessed this light source into a single beam and direction, the intensity increases, giving us close to 20,000 candela.
Lumen - Lumen is used to indicate the amount of light available from the light source, the value being supplied by the Manufacturer of the light source i.e. LED, Halogen or HID Globe. 1 Candela is approx. equal to 12.57 Lumens for comparison.
In the early years of KC Hilites, the owner Peter Brown worked closely with GE Company (Lighting) to understand the differences above, filaments and how wattage, candlepower and light and reflector construction affected light output. In the early 1970s KC offered the KC Daylighter in 150 Watt Halogen globe, encased in a rubber mounted, shock proof housing for off-roading. This formed the basis of KC Hilites and has since evolved into their class leading products they offer their customers today.
