The simple yet versatile one lens and one switch headlamp for the user that doesn’t need any bells or whistles and just wants a simple light. This user has the need to run the lamp on alkaline batteries if caught away from a power source for a long camping trip. Digital lock mode feature safeguards against accidental use when stored in a pack or pocket. Brightness Memory allows you to turn the headlamp on and off at last used brightness level without reverting to max brightness. It has a rechargeable BD 1500 Li-ion battery.
