Having a bright flashlight on you is a great idea, especially for those of us who have chosen to carry a defensive firearm. However, sometimes you need both hands to complete a task, and that's where a bright headlamp comes in really useful. 

Cyclops is known for making innovative personal and field-lighting solutions. Now they are introducing a new multi-light headlamp designed for the grab-and-go adventurist or for anyone who needs a handy, hands-free light source for working around the home or in the shop.

The new Cyclops eFLEX 400 features a rugged ABS housing that is secured to a comfortable and adjustable headband. The headlamp has soft-touch switches on the left and right sides and a pivoting head that blends ergonomics with practical function. The eFLEX 400 is powered by a 3.7V/400mAh rechargeable battery, and dual light sources allow the user to customize the illumination to meet specific tasks.

The primary light is a 400 lumen Cree XP-G3 4W LED, while the secondary LED allows switching between red, green, blue, and white light. There are also hgh, medium, and low illumination to allow you to set the right amount of light for the job while maximizing battery life, as well as an SOS strobe mode.

The eFLEX 400 housing is IPX5 waterproof, making it suitable for use in rain/snow conditions. The headlamp comes with a USB charging cable for convenient recharging.
