Photon Standard Dive Light

Powerful, precise, and built to last — a professional-grade dive light engineered for night dives, technical diving, and everything in between. The Halcyon Photon Light delivers up to 1200 lumens of focused, regulated brightness through a narrow 9° beam — making it an exceptional choice as a primary or backup light for recreational, night, and technical divers alike. Built from aircraft-grade aluminium with military-grade hard-anodising and triple O-ring sealing, the Photon is rated waterproof to 200m and engineered to perform dive after dive in the most demanding conditions. With dual power modes, flexible battery configurations, and a simple twist-on/off activation, the Halcyon Photon is as intuitive as it is powerful. Whether you're running on the included 3× alkaline C-cell batteries or upgrading to optional lithium-ion cells for maximum output, the Photon gives you full control over runtime and brightness to match your dive profile. The Halcyon Photon Light (3-C Cell) is equally at home on a casual night dive as it is in overhead or technical environments — a reliable, no-compromise light for divers who demand consistency and durability on every dive.
