I have tested at least 50 torches from various manufacturers. You would be surprised how many simply conk out after a good tough trial or indeed trail. Out of all of the ones tested, this was my absolute favourite and the one I still choose to take with me whether working on-stage or outdoors in the hills or at sea. Amazingly, it has just been upgraded giving even more power AND longer battery life! The battery life seems lower in the specifications because it is now measured to a different standard [to 30% power], it has in fact increased in duration. Black.
The reason I score this torch top marks is:
Batteries: 1 x AA. Dimensions [defocused]: 113 x 26 mm. Beam length: 120 m. Battery duration 4 h. Weight [with battery]: 80 g. Water Resistance: IPx4.
