With an abundance of lighting products and technology on the market, the topic of how to measure light efficiency can be rather confusing.
Watts are a measurement of energy consumed by a light source. In the past, when most systems were using similar halogen bulbs, understanding that a 15-watt system will be brighter than a 10-watt system was simple. Now, not only are there different technologies of halogen, HID and LED, but the same wattage of LED will not necessarily produce the same amount of light. Thus, we can no longer consider watts as an accurate way to measure light output.
Lumens measure the total amount of light that a specific light system produces. Although lumens are an accurate measurement of light output, it says nothing about the efficiency of light projected. Respectively, a lighting system with a high lumen output may not be designed to utilize the light properly for cycling.
Candlepower is the specific measurement of projected light. As a preferred method of measurement by Cat Eye, this useable light is the result of complete consideration of the lighting system from the batteries and circuitry that drive the light source, to the lens and reflector that project the light.
As a result, with every Cat Eye product, you can be confident that all aspects of the light have been measured, refined, engineered and designed to exceed your expectations.
