Halcyon Proteus 6

We like to think of the Proteus 6 as the Swiss Army knife of primary lights. It offers a budget alternative to the Explorer NiMH line. The tried-and-true lead-acid battery pack has been trusted for over a decade to provide reliable and affordable power while be able to drive a wide array of Halcyon light heads.

  • Unbelievable burn times of over four and a half hours with the 10 watt HID light heads
  • Excellent choice for extended-range open water and overhead applications
  • Fine balance between maximum versatility and streamlined design

The Proteus 6 adds 3 lbs. of ballast to a diver's rig, making it suitable for wet suit and dry suit diving.

All Halcyon Proteus lights come standard with a host of valuable features, including: temperature resistant Delrin light heads; commercial-grade strain reliefs to reduce light cord stress; deep recess bottom plates to increase strength and support; inset bottom channels to prevent battery movement; superior quality rechargeable lead acid batteries; triple fold belt loop attachment; automatic shut off charger with charge light indicator.

The Proteus canister carries a lifetime warranty against breakage and maintains a material operating temperature of -100' F (-73'C). The amazing ability of the canister to resist shock is partly attributable to its slightly flexible nature. Destructive testing efforts included repeatedly dropping the canister from a height of 10' filled with 35lbs of weight, pounding on the canister with a 5 lb sledge hammer and driving over it with a car. All efforts to crack the canister or break off the bottom were completely unsuccessful. Hydrostatic testing to over 700' was entirely uneventful. Halcyon is proud to lead the way into a new age of underwater lighting.

DIR Tip 21
Placement of the lights is a very important aspect of equipment configuration, second only to the placement of the air delivery system. Divers usually store the primary light on their right hip where it can be easily reached, removed if necessary, and reviewed for stability.

Other mounting locations, such as hanging the canister from the bottom of the tanks, are inferior to placement on the waist. For instance, consider how butt mounting a canister light impacts a diver’s buoyancy characteristics. The diver in an overhead environment must preserve a "feet up," horizontal trim to reduce the risk of disturbing sediments-- one of the most fundamental rules (and essential skills) in overhead diving.

Butt mounting places the canister below the tanks, resulting in a shift that tends to drag the legs down, especially if the light canister is flooded. The resulting feet-down posture can pose a very real danger in some environments, made all the worse in that butt mounting prevents easy removal of the light. The greatest disadvantage to this mounting location occurs when the diver experiences a problem with the light, such as a flooded canister, a line entanglement, or a failure of the attachment hardware.
