This includes the StenLight S7 Premium headlamp only. You will need the Battery and Charger in order to use the light.
Uses top-grade Luxeon Rebel LED's which are 40% brighter than the 07 Stenlights and nearly 100% more efficient than the earliest S7 Stenlights. The StenLight S7 Premium is a high powered LED lamp designed especially for the hostile caving environment. Mud, water, and shock-resistant, the S7 was designed by cavers to address the shortcomings of conventional cave lamps. Key Features: Brightest portable LED light available. Uses Luxeon Rebel LED's. Extremely long LED life (>20,000 hours) Solid state and shock-resistant, no breakable filament or gas-filled tubes. Flicker-free all-analog control circuit provides current regulation at all brightness levels for constant brightness. Operates off any 6 to 18 volt DC power source. High electrical and optical efficiency make the most of your batteries (96% electrical efficiency from 7.2V, 93% from 12V). Compact, rugged anodized aluminum case. Lightweight -- under 125 grams. Long throw, high durability magnetic switch. Water-resistant up to 25 feet (no moving parts penetrate the sealed lamp body). Smooth, optimized beam pattern with user-swappable lens options. Temperature limiting to prevent overheating of LEDs or exterior. Four logarithmic brightness levels. Swivel bracket supports easy adjustment of a wide range of vertical angles. The StenLight S7 uses a high-efficiency all-analog control circuit that regulates LED current in all brightness modes, and limits itself to a safe temperature by reducing LED current when necessary. The magnetically controlled switch has 5 clearly-defined positions that are separated to avoid accidentally switching the unit off. The switch has no moving parts inside the lamp body, and is fail safe, if the switch is destroyed or the magnet lost, the unit defaults to the LOW setting, which is still bright enough for you to find your way.
