This is a CAT EYE bicycle headlight. It's the type that attaches under the handlebars. Purchased new a few years ago at Bic Camera. It was mounted on a road bike and used for about 300km. It has been unused since the COVID-19 pandemic. I've charged it about once every six months, so the rechargeable battery is in good condition with no noticeable wear. It's in good condition, but there are some minor scratches from use. Please refrain from purchasing if you are a perfectionist. I will sell it to someone who understands that it is a used item. - Light body (Slight scratches on the screws of the mounting part. See photo) - Mounting bracket (H-34N) - USB charging cable (Micro USB) - Outer box Model number: HL-EL551RC Price: ¥5,800 Light source: LED Candela (cd): 7000cd Size: 35.9 x 106.5 x 46.5mm Weight (body + battery only): 96.5g Usage time: High: Approximately 7 hours (260 lumens) Middle: Approximately 9.5 hours (200 lumens) Low: Approximately 40 hours (50 lumens) Standard charging time: Approximately 4.5 hours Number of charge/discharge cycles: Standard 300 times (until the capacity drops to 70% of the rated capacity) Waterproof performance: IPX4 Cut-off light distribution that considers glare to the surroundings Rechargeable light specifically for mounting under the handlebar 5 modes: High, Middle, Low, *Daytime Hyper Constant, and Flashing Double-click to switch to High mode Easy USB charging (Micro-USB cable included) Battery indicator to show charging timing Mode memory function to start lighting in the mode when turned off Can be used during the daytime as a daytime running light #Cateye #Light #Headlight #LED #Roadbike #Crossbike
