Lightstores HTA Glow Stick Waterproof 10 Meter Rated

The Lightstores HTA Glow Stick Waterproof 10 Meter Rated is the dive-optimized format in the HTA product line — engineered specifically to maintain full seal integrity and uninterrupted chemiluminescent output at water depths up to 10 meters, covering the working depth range of recreational scuba divers, underwater search and rescue divers, and commercial inspection divers who use chemiluminescent sticks for equipment and diver identification at depth. The 10-meter pressure rating of the HTA waterproof format is achieved through a double-layer silicone gasket sealing system at both the connector cap junction and the body-to-cap transition — the two locations where standard glow stick designs rely on compression fit alone and where hydrostatic pressure at depth is sufficient to force water intrusion into the chemiluminescent fill chamber. The double gasket system provides redundant sealing at both locations, ensuring that a dive to the rated depth does not compromise the fill chamber integrity even when the stick is exposed to pressure cycling through multiple descent and ascent profiles during a single dive session. The connector cap design in the waterproof format is modified from the standard HTA connector to include a retention locking ring that prevents accidental disconnection from dive equipment attachment points under water current and movement forces that could disengage a standard push-fit cap during an active dive. The chemiluminescent fill and 12-hour rated runtime are identical to the standard 8-inch HTA format — the waterproof construction adds no performance penalty to the illumination specification, only the additional sealing engineering required for the pressure-rated application. Available in green and yellow as the highest-visibility wavelengths at typical dive depths. Dimensions: 20cm × 1.5cm diameter.
