Halcyon Flare lights have a Lux output of 11,500 at 1m. The runtime on its 5amp Li-ion battery at High Power Setting is 300+ minutes. Runtimes increase by three fold on the torch's Low Power Setting (through a magnetic switch controlling off, low and high modes).
The Halcyon FLARE™has three sealed compartments, isolating the LED core, the driver, and the cable gland.
Halcyon Measuring Diving Light
Halcyon prefers to describe diving lights using lux because this provides a gauge of intensity at a given distance, which is probably more relevant while diving or during signaling. Halcyon typically tests lux output at one, three, and five meters from the light source. These distances appear useful when evaluating intensity for general use and while signaling a dive buddy.
Lux is a measurement that defines light intensity at a given distance. A lux measurement that is very close to the light source will be higher than a lux measurement recorded farther from the same light source because light diffuses as it gets farther from the source. Therefore, you can think of lumens as the amount of light available and lux as the lumens that are actually arriving at the intended target.
