This is a recent upgrade from our old NR-700. It has all the same features as the original light, but with an upgrade in the LED, it is now 1000 lumens, for the same great price! Built from rugged anodized aluminum this light can stand up to any environment. Included 18650 battery has a USB charge port built right in so no extra cradles required for charging. This keeps it simple and easy for packing. Hard attach point on the rear for using the included lanyard, or a bolt snap if that’s your thing. Oh yea, and that is a bottle opener for quick access to your favorite beverage after a dive. 🙂 Push button on\off means quick and easy to use, no more worrying if you’re turning the head the right way! Built in battery level indicator notifies you I’ve you’ve got a full charge before you get in, and let’s you track your usage during a dive. The light features 3 power levels and an SOS mode.
