The precise design of the VRH300 USB Rechargeable Headtorch makes it the ideal choice for fishing, hiking or camping. The VHR300 is encased in a handy rubber housing and is not only durable, it is also water and dust resistant. The VRH300 not only looks great, but also has a smart dual oriented design. There is no upside down. It doesn't matter how you put it on - you can't go wrong! In addition to three standard white light beam options, the VHR300 can also emit a powerful green light that can be adjusted to your preferences, and because the human eye is more receptive to green light than red, you retain great night vision AND bright lighting. Your eyes will be grateful. The internal lithium polymer cell battery is fully rechargeable and compatible with all USB chargers. Forget batteries, the four-step battery indicator ensures that you will never be left in the dark.
