Intense and uniform illumination of the workplace supports precision and quality of work especially in craftsmanship workshops. For example, in the automotive industry, working lights illuminate parts of the engine that cannot be reached by a ceiling light. The use of a automotive charging cables for continuous bright light is practical. Protected against acid, oil and mechanical abrasion, it has multiple application areas. Rechargeable hand-held spotlights are a great help not only as traffic signals. They can be used even as emergency lighting during power outages. Thanks to tilt and swivel design, table lamps are particularly flexible and welcome not only in poorly illuminated offices. They are also an advantage with delicate manual work, such as in soldering, carving or modelling. Finally, machine lights can be directly fixed on the unit and optimally illuminate the work area.
