Brand: ANTAREX (Made in Japan) Model: MRX25 (LED) Brightness: Approximately 2,000 - 2,500 lumens Battery: Attaches to the frame or handlebars with the included Velcro straps Size: (Head unit) 6 x 3 cm (Battery unit) Length: 24 cm Diameter: 18.5 - 19.5 mm Power: Alkaline batteries, AA x 4 *Batteries in photo 6 are not included Accessories: Velcro straps for battery attachment x 2 *The length of the Velcro straps has been partially modified, but they can be used without problems on other vehicles (difficult to see in photo 5) *Operation confirmed (photo 2). The switch is on the battery cover. Made of aluminum, it has high heat dissipation, is lightweight, and has a high-quality feel. The light unit and battery unit are connected by a coil cable, making it easy to handle. Especially when paired with a randonneur or chromoly frame, it gives a very vintage feel. Both the brightness and the beam range are very powerful, and because it uses dry cell batteries, you can enjoy touring without worry even on mountain roads after sunset if you carry spares. Operating time is approximately 2-6 hours (according to manufacturer's data). I used it once for a brevet, and since I haven't had a chance to use it since, it has been stored at home. Apart from the modification of the Velcro straps, it has no signs of use, and there are almost no scratches. However, it is a used item, so please consider it only if you understand. There is no original box. It will be carefully wrapped with bubble wrap and shipped in a recycled box.
