I confess: I am not the most coordinated of people. I tend to walk into things, trip over my feet and drop stuff. Unsurprisingly, my kit suffers for it.

Prism 100 is composed from hardy aluminium with a soft rubber head plate. This construction gives Prism 100 impressive durability. It has high resistance to impact and corrosion. So, if you are a little bit butterfingered like me, it will survive longer than most headtorches would!

With an IPX7 rating, Prism 100 can sustain being submerged in 1m of water for up to 30 minutes. So, if you drop it in the river you are crossing, it will be usable when you retireve it. The headstrap has a securing top strap making it ideal for runners, kayakers and moutaineers.

Prism 100 has a projection angle with free 180° movement and a burn time of up to 5 hours and 30 minutes. On maximum output, Prism 100 has a lighting range of 130 m. Weighing in at only 101 g, Prism 100 is a tactile 59 mm in length- fitting charmingly in the palm of your hand.

There are 4 modes of operation on Prism 100: high (100 lumens); medium (55 lumens); low (20 lumens) and 8 Hz flashing. There is also a lock mode to prevent accidental battery drainage.

Packs a punch

I bought one of these just before a night navigation course I did in preparation for my ML assessment. It was awesome and wowed everyone including our instructor. On the night nav section of ML assessment it performed superbly in foul conditions. My only niggle is that it doesn't have a zoom/wide angle option. But for the price the build and quality are unbelievable. Just buy one - you won't be disappointed.
