The Dedolight system was conceived and designed by German director of photography Dedo Weigert. As is often the case it started out purely to meet the requirements of his own projects, for which he wanted a powerful but highly controllable light source that would not take up much space, draw a minimum amount of electricity and produce unprecedented light quality.
Weigert's development work began in 1963, leading up to the first Dedolight being built in 1984. For several years only one model and size was available but the concept ultimately went beyond being a lighting device for Weigert's own purposes to something that is now used widely in film and television production and still photography. The main features of the Dedolight are: ultra compact size, light output equal to those of much larger sources, precision lighting with beam and stray light control, even light distribution, good reach, precise colour temperature control, a variety of projection attachments and accessories, versatile mounting accessories, a range of power options, low projected heat and rugged construction.
By 1990 Dedolight and the optical principle of a dual lens construction on which its products are built were well established, something recognised by the Academy of Motion Picture Arts and Sciences with a Technical Achievement Award. Today Dedolight's range includes LED fixtures alongside the more traditional daylight and tungsten forms of lamp, with portable studio kits and soft lights and boxes also available.
