How bright is the Maxa Beam Searchlight? How is this measured?

The Maxa Beam Searchlight has an output of 12,000,000 CandlePower*. CandlePower measures the intensity of the light that hits a target at a distance, which makes this unit of measure valid for searchlights and other focused light sources that will be used to illuminate specific targets at long ranges.

The measurement and calculation of Candlepower (also called candela) is defined by the ANSI/NEMA FL1: Flashlight Basic Performance Standard.

To determine the Maxa Beam’s CandlePower measurement, the searchlight is focused down to a tight 1° beam and pointed at a target placed at a known distance.  A data-logging light meter is used to measure the light intensity illuminating this target. The measured lux value is multiplied by the distance to the target squared to calculate the searchlight’s CandlePower rating.

Peak Beam Quality Technicians test the output of every Maxa Beam Searchlight on a 25 meter range.  If requested, Peak Beam can provide a Certificate of Conformance identifying the output of any new Maxa Beam Searchlight at time of shipment.
