LFM LED is a lightweight magnifier with an all-metal construction, LED light sources, and a flexible spring-balanced arm in the Luxo tradition. The arm provides long reach and maximum vertical and horizontal movement, and will always stay in the right position without drifting. The flexibility of the joint between lamp head and arm makes exact positioning easy. LFM LED is equally well suited for professional use as for use by the visually impaired and others with a need for precise magnification. Being lightweight makes it easy to move around. LFM LED is easily mounted with a removable table edge clamp. Shadow-free magnification The ø127 mm glass lens is positioned in the middle of a circle of LED light sources. This is the ideal way of illuminating an object, virtually eliminating shadows. LFM LED is supplied with a 3 or 5 diopter glass lens. A cloth cover is provided to protect the lens from dust and to prevent the luminaire from inadvertently turning into a burning glass. LED: Light source of the future! LFM LED is equipped with a full circle of LED. It has three-step dimming (100%-50%-0). The diodes automatically turn themselves off after 4 or 9 hours in order to save energy.  LED's have an incredibly long life span. The diodes in LFM LED have a life expectancy of 50,000 hours. That means 25 years or more with normal use. You will never have to change the light source!
