Thank you very much for viewing! This is a GENTOS LED headlamp (HW-G533H), a proven product from GENTOS, a well-known brand. It's brand new, unused, and unopened. I also use this, and it's quite bright at 600 lumens. It's bright, and I can keep my hands free, which is very convenient. It's a great item for not only disaster preparedness but also for walking, fishing, and work. The retail price is 6578 yen, so I think it's a great deal. How about it? Although it's unused, it has been stored at home, so please understand this before purchasing. 【Features】 Light Source: High-intensity chip-type white LED x 1, High-intensity chip-type warm-color LED x 1 Brightness: Approximately 600 lumens (maximum) Batteries Used: Dedicated lithium polymer rechargeable battery 3.7V 1,800mAh (Charging time: Approximately 2.5 hours, Battery life: Approximately 300 charge/discharge cycles) Or 3 x AAA alkaline batteries Operating Time: Approximately 8 hours (High mode) Approximately 13 hours (Mid mode) Approximately 27 hours (Eco mode) Beam Pattern: Slide focus control type Beam Distance: Approximately 142m (maximum) Protection Grade: Dustproof and splash-proof (IP64 compliant) Drop Resistance: 1m drop resistance (light unit only) Body Size: Head Unit: W73.1 x H52.8 x D38.8mm Battery Box: W84.8 x H53.8 x D30.4mm Approximately W66.8 x H45.5 x D42.8mm Body Weight: Approximately 190g (including batteries) 【Accessories】 ・Headband with non-slip ・Silicone band (4 buckles) ・Helmet holder x 4 ・Micro USB cable (50cm) ・Dedicated rechargeable battery Brightness (lumens)...500-999lm Type...LED light
