Ammonite Led One Back up light,

The Led One torch from the Polish brand AMMONITE is a compact torch perfect as a backup for any diver. The handle of the Led One torch is made of delrin, while the head is made of anodised aluminium. Led One is equipped with a LED as a light source. The diode is powered directly from the battery without any additional electronic circuits, which is why Led One is so reliable. The head and the handle are connected by a long thread sealed laterally with three O-rings. This eliminates the possibility of accidentally flooding the torch by unscrewing the head from the body too hard when turning it off. The corrugated handle makes it easy to hold and also allows you to use the torch as an auxiliary tool for attaching a harness made of a single piece of webbing.  The eyelet at the end of the body allows a 6mm diameter cord to be threaded through.
