Used item. I used it for night competitions, attached to a mountaineering helmet. It's a bit heavy because it uses three AA batteries. The helmet clip component is missing. Please be aware of this if you are considering it for work. Instruction manual included. Batteries included (used). I am unable to check and reply to comments during the day. To prevent any problems, I apologize, but I would appreciate it if we could proceed with the transaction at the listed price. Since it exceeds 3cm in thickness, shipping will be in a box instead of an envelope. Thank you. The following is an automated description: Tajima headlamp with LED light, operates on 3 AA batteries. - Brand: Tajima - Type: Headlamp - Power Source: 3 x AA batteries - Brightness: LED light (50~500lm)
