We send a Free Nitecore F1 Flexbank charger with every Concept 1.
The Nitecore Concept 1 is the first torch in the Concept series. Utilising a Cree XHP35 HD E2 LED it has a maximum output of 1800 lumens. The included IMR battery has a high discharge current of 10 A to drive the LED to the fullest and incorporates a protection module for added safety. We recommend to charge the battery with a Nitecore battery charger that is designed for IMR batteries to ensure compatibility.
The Coast EAL17 lantern runs off of 4 x D cell batteries and offers up to 50 hours of run time in low mode and delivers a maximum of 460 lumens of white light at full power. It also has red LEDs that can be turned on to provide light but still preserve your eye's natural night vision or you can activate flashing mode to signal for help.
