The HALCYON Focus 2.0 diving torch is a breakthrough in underwater lighting technology and offers twice the brightness of the original Focus 1.0 light. Note: this is a light head only. With E/O connector.

Halcyon Focus 2.0 LightThe 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.

Features at a glance:

  • e/o cord
  • High Setting: ~80,000 Lux at 1 metre / 1,550 Lux at 5 metres
  • Low Setting (Half Power): ~39,000 Lux at 1 metre / 775 Lux at 5 metres
  • Adjustable power switch may be set to Off, Low, or High power
  • Adjustable beam angle from narrow to wide
  • Adjustable handle, folds on lens during transport
  • Not included: battery canister with e/o cord or charger

Halcyon Measuring Diving Light

Halcyon Fresnel Lens Torch Focus 2Halcyon 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 VS Lumen from Halcyon Dive Systems on Vimeo.

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.


 

Focus 2.0 Tightest Beam (Surface)

Halcyon Focus 2.0 Beam Surface Test

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.

FAQ - What is an E/O Connector/Cord - do I need one?

E/O Fittings (wetmates) are versatile pluggable two-pin connectors which allow divers to utilise their batteries with more than one light head, heating systems etc. by allowing the diver to change what the battery powers. A male-female E/O connector at end of the battery side cord will require a male-female E/O connector on the cord leading to light head or heating system.  The term E/O comes from the first manufacturer of such fittings: Electro-Oceanic Inc. but current connectors on the market are totally new generation,  still referred to as E/O or underwater pluggable cords/connectors. E/O cords may require more care and maintenance than continuous cables especially when/if exposed to salt water. It is recommended the connectors are cleaned and well maintained between dives, not directly exposed to salty conditions.

If you are using your battery canister only to power up your torch, a standard cable will suffice. If you intend to change light heads or use the battery to power more than one element (i.e. torch and any heating system) ensure the battery meets the power requirement of both systems combined. E/O cord option on this item means the battery/canister will have a cord with E/O fitting at the end and the light-head will have a cord with mateable E/O fitting on the torch end. When not in use, each connector can be protected with a Blind [Dummy] Plug.

E/O Y Connector & Blanking Plug

Wetmatable E/O connectors have a wide range of compatible accessories. E/O Y-connectors and Blind [Dummy] Plugs are the most popular accessories used by divers. The Y-connector, also called a Y-Splitter, consists of three waterproof two pole connectors in a single device allowing output to be shared between two devices/systems (i.e. two light heads, a light head and heating system etc) from the same power source. A Blind [Dummy] Plug is a simple two pole dummy connector for protecting unmated connectors against the elements.  These are ideal for heated vests and canister batteries during transport.

Keep in mind: E/O connectors are delicate and any contaminants such as grit, sand, salt residue and similar inside the connector will not allow a connection to be made and could irreversibly damage the cord end.
