LEDLENSER produces high quality focusable LED torches and focusable LED forehead lamps (LED head lamps) for industrial use. The lamps are convincing through their high lumen and numerous model-dependent additional functions (e.g. dimmable, strobe, roll-away protection, High Power/Low Power). The LED lights can be operated with batteries, rechargeable batteries or with Li-Ion batteries that can be recharged with USB.
