The simplified, multi-function design provides dynamic flexibility without confusing complexity. At 7.5 inches long, with a 1.6 inch bezel and a 30 mm body, the H3X Regulus fits standard 30 mm ring mounts and is water resistant to 5 meters (15 feet). Its high output 160 lumen LED blub runs two hours on high and 300 hours on low setting off of three three-volt batteries. Modes include constant, momentary, strobe and dimming.
