Lifesystems Intensity 80 (2012)

On first appearances the Lifesystems Intensity 80 looks very much like the Alpkit Gamma, but it has some important differences. Primarily the Intensity 80 has a motion sensor that allows you to wave your hand across the front of the headtorch to turn it on and off. The benefit of this is that it makes it extremely easy to operate the headtorch while wearing big gloves, which otherwise would be difficult. However for me one problem was that when you want to tilt the head to direct the beam you inevitably switch the torch on or off. I found this frustrating and would much prefer just to have the beam switched either on or off, via a well-designed big button (the button switch on this torch is a master power button). The Lifesystems Intensity 80 does not get a battery power indicator either, nor does it have a red LED for mapreading and preserving night vision. But having two white LEDs that are not operated via the motion sensor is useful. There’s also a red light on the back of the battery pack. For the price you are getting some good features, but I’m not convinced the motion sensor is one of them.


Bulb 1 x high power LED; 1 x red LED; 2 x white LED; 1 x rear red LED

Brightness 80 lumens

Maximum beam 70 metres

Minimum burn time 50 hours

Batteries 3xAAA

Battery charge indicator no

Weight with batteries 118g




If you like the motion sensor light activation then the Lifesystems Intensity 80 is a headtorch offering a good range of features for general walking and camping at a very competitive price.
