The Ledlenser i6 is a slimline penlight offering a maximum output of 140 lumens and a beam range of up to 120 metres on the highest setting.Made from robust aluminium, it also features the industrial series' signature yellow ring on the inside of the head and yellow detailing on the switch, which is great for visibility in a work place environment.Featuring the Advanced Focus System (AFS), the patented combination of a reflector and lens allows the i6 to create a light system that provides both a focused beam for long-distance and a homogenous spill-beam for up-close activities. You can quickly focus between spot and flood by sliding the head of the torch backwards and forwards.Simple to operate, it has a push button switch on the tail that cycles through the two brightness settings of high and low, with half presses of the switch. Alternatively, one press turns the light on in high and the next press turns it off. A third press turns the torch on in low and the next press turns it off.It uses three AAA alkaline batteries, with superior gold-plated battery contacts to help resist corrosion and keep the battery running well.
