Sofirn SR15 4500LM USB-C Rechargeable 21700 Flashlight

Light up the night with your 4500-lumen beacon that throws a long-range beam up to 510 meters for your outdoor adventures and emergencies.

• You get ultra-bright long-throw performance: four SFT25R LEDs deliver a crisp 6000–6500K white beam, reaching 510 meters for precise distance lighting.
• You can choose from five brightness levels from 1 lm to 4500 lm, enjoy stepless dimming, and access emergency modes (Strobe, SOS, Beacon) when you need them.
• You’re powered by a rechargeable 21700 cell and USB-C charging; a buck driver keeps output stable, and it doubles as a power bank to charge other devices.
• You’ll appreciate the rugged, compact build (130 mm, 128 g) with memory function and lockout to prevent accidental activation; note the tail cap is glued and requires unscrewing the head to replace the battery.
