The arm is optimally balanced and holds in any position without readjustment. For safety reasons, operates with non-hazardous extra-low voltage via a separate, GS-approved power supply unit. Light colour similar to daylight (6500k), thus objects are displayed in neutral colours. SMD LED modules for high luminosity and good light quality with optimum heat dissipation. Suitable for many applications such as cosmetics, precision mechanics, electronics or simply as a reading aid. Three different available magnification factors of the lens allow almost unlimited application possibilities. Choose a slightly smaller magnification because, for technical reasons, distortion increases at high magnifications. Also excellent for use as a desk lamp. Removable lens cover does not break when subjected to rough impacts, but slides out of the bearing with a deliberate, slight play and is easy to replace. 3 dioptres (model 7213MKIII), corresponds to 1.75x magnification (175%), universally applicable. 5 diopters (model 7215MKIII), equivalent to 2.25 times magnification (225%), universal use. 8 diopters (model 7218MKIII), corresponds to 3-fold (300%), particularly suitable for the highly magnified display of very small objects. Scope of delivery: 1 piece magnifying lamp including power supply unit, 1 piece table clamp for table tops up to 65 mm, 1 piece manual.
