The Nitecore HA40 is a die-cast aluminium head torch that features a separate battery case and provides a maximum output of 1000 lumens from a Cree XM-L2 U2 LED.
The wide 90° angle beam, high lumen output, IP66 dust and water resistance rating and lightweight die cast body are all features that make this head torch great for caving as you want to have a wide area of illumination so you can easily find your way on the uneven ground and also have a unit that can withstand the damp conditions or dripping water. The HA40 is also good for climbing, camping, mountain climbing, map reading or for mechanics who need their hands free and a wide area of light.
The headlamp sits on the front of the headband while the plastic and silicone battery case sits on the back of the head band for evenly distributed weight. Four AA alkaline/NiMH batteries power the head torch and sit inside the separate battery case. To open the battery case simply remove the silicone cover from around the plastic casing and insert the batteries. The battery case is easily accessible yet still stays in place when closed and there's no fiddly plastic clips to open the case, so it won't break like some other external battery packs.
Five brightness levels as well as three special modes are available. Hold down the push button for 0.5 seconds to turn the light on and off. A single press from off will instantly access ultra low and a long 1.5 second press and release from off will instantly access turbo. With the light on, single press the push button to cycle through ultra-low, low, mid, high and turbo. The light will remember the previously used brightness levels.
To access the special modes quickly double press the button while the light is off. Single press will then cycle through SOS, beacon and caution light. The special modes cannot be memorised.
The advanced temperature regulation allows the HA40 to regulate its output and adapt to the ambient environment, maintaining optimal performance.
