Thank you for viewing. This is the LEDLENSER Redlenser Rechargeable Headlight Blue NEO10R, priced at ¥11,000 (tax included). I purchased this for trail running, but I haven't been using it lately, so I'm reluctantly putting it up for sale as part of a decluttering effort. The battery pack can be stored in your backpack, so you won't feel the weight while it's on. It's incredibly bright and has a long burn time, so you can use it with confidence at night. It's ideal for trail running and trail running, but it's also suitable for nighttime use in activities like mountain climbing, marathons, jogging, and fishing during the upcoming season. Please consider this item with the understanding that it has been handled by another person and will be shipped in simple packaging. The NEO10R perfectly balances "bright, lightweight, and long-lasting." It's an improvement over the previous MH10 model, with a vertically arranged battery box and a double band for an improved fit. By storing the battery box in your backpack using the included extension cable, you can make it feel so light that you'll forget you're even wearing a light. It's especially recommended for uses like trail running.
