This 150-gram lightweight LED headlamp provides a light intensity of 205 lumens for more than four hours. The Walther Pro HL11 has three light output levels and a strobe mode and can be focused with one hand for a wide field of vision for activities such as jogging. In order to prevent cable breaks as a result of heavy strain, the newly developed HL11 is designed with the battery compartment within the lamp housing. The headband provides a pleasant non-slip fit while the cloth straps can be easily removed for washing.
