Lumens vs. Candlepower
Lumens, en forklaring! We rate the light output of our products in lumens. The lumen is a measure of the amount of light, as opposed to the intensity of light. A typical 75-watt incandescent light bulb has an output of 1080 lumens. At a distance of ten feet, this light bulb would provide uniform illumination of slightly less than one lumen per sq. foot.
Another measure of light is CANDLEPOWER, which is not a measure of the amount of light but a measure of intensity at a given point in a focused beam. Because such a measure produces impressively large numbers, it is often quoted by other manufacturers.
For example, the above 75-watt bulb equipped with a reflector could be rated, under certain conditions, as producing over 2 million “candlepower”! Since this “rating” is highly dependent upon which point within a given beam is being measured, candlepower ratings can be very unrealistic and, therefore, certainly not a true measure of the amount of light a flashlight produces.
That is why we choose to rate our products in consistent LUMENS (Quote: SureFire).
