Silva Explore 4RC headlamp — 400 lumens, IPX7 waterproof, USB rechargeable, white/red/orange modes, multi-mount. No disposable batteries required.
The Silva Explore 4RC is the rechargeable version of the Explore 4 — same 400-lumen output, IPX7 waterproof rating, and multi-mount versatility, with a built-in rechargeable battery instead of AAA batteries. USB charging eliminates the need for disposable batteries on multi-day trips. White, red, and orange light modes cover general use, night vision, and map reading.
