Halcyon Photon (3-C Cell) Backup Light– No Case
Part #20.105.109
Maximum Runtime. Serious Primary Light.
The Halcyon Photon (3-C Cell) is a powerful, full-size handheld dive light built for Puget Sound night dives, low-visibility conditions, and extended runtimes. With the same tight 9° beam found across the Photon line, this light delivers excellent penetration in plankton-rich water while providing a bright, defined hotspot for clear communication and navigation.
The larger 3-C cell power format provides longer burn times and sustained brightness, making this an ideal primary light for night diving, deeper profiles, and cold-water environments where reliability matters most. Its robust, hard-anodized aluminum body, triple O-ring sealing, and glove-friendly twist operation make it well suited for Northwest diving in real-world conditions.
This version ships without a protective case, making it a great option for divers who already own a Photon case or prefer a streamlined, no-extras setup.
Why It Excels in Puget Sound
Tight 9° beam minimizes backscatter in low visibility
Longer runtime for night dives and extended bottom times
Bright, consistent output for clear signaling and team awareness
Glove-friendly operation for cold-water diving
Durable construction built for frequent local use

When visibility drops and dives get longer, runtime matters. The 3-C Cell Photon delivers dependable brightness with a beam that actually works in local water. It’s a no-nonsense primary light that earns its place on night and low-vis dives.
