A torch that needs no batteries: by simply twisting the torch, the built-in generator produces electrical energy. This is stored in a capacitor which, in contrast to a battery, never corrodes and can be charged and discharged several 100,000 times. After just 10 seconds of twisting, there is enough energy for 10 minutes of light. The three built-in Nichia LEDs are virtually indestructible and have over 100,000 hours of life. Their light is focused by a precision lens made from acrylic. The Everlight consists of an extremely robust, splash-proof polycarbonate body which guarantees use in extreme and inclement conditions. Ideal for the car, the home or on a boat. Light visible up to 1 km. 7,000 lux. Length 14.5 cm, weight 150 g.
