The Halcyon Focus 2.0 Black 2023 edition dive light will run up to 2.5 hours in high mode or 5 hours in low mode, making it ideal for a weekend of diving or any dive with long bottom and decompression time.
Its adjustable beam ranges from narrow “technical/signalling” mode to very wide mode.
The black body Halcyon Focus 2.0 uses two reflectors and a Fresnel lens to provide full focus adjustability with amazing output and greatly reduced power consumption.
The torch has three sealed compartments, isolating the LED core, the driver, and the cable gland. High-performance capacity is further augmented by a fully-adjustable handle, which can be set for left or right-hand operation and folded over the lens for protection during transport.
These unique features are powered by a small but powerful battery.

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 signalling. 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 signalling a dive buddy.
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.
Focus 2.0 Tightest Beam (Surface)
When switched on at its tightest beam the Halcyon Focus 2.0 will produce a square beam with a halo around it. The beam will reflect 4x LEDs with a darker “cross” in between which will disappear when the beam is slightly tuned out as below. Left: Beam at distance, Right: Beam closeup.
* Note that switching on the Focus 2.0 may cause interruptions and/or fully interrupt the frequency range of DAB (radio) at close distance
