For many years our founder Dedo Weigert worked as a Director of Photography and producer on film projects all over the world. Not content with the ordinary tools of his trade, he constantly sought technical innovations in lighting, leading to over 30 international patents.

The design of studio lighting has long been dominated by Fresnel lights, a technology based on principles dating back to the beginning of the twentieth century. Inspired by his experience in film, Dedo Weigert built on this traditional concept with a revolutionary new optical system, increasing light output, efficiency and improving control. While traditional studio lights achieve a focusing range of 1:3 (maximum 1:6), dedolight optical systems offer 1:25 (up to 1:53).

dedolight’s award-winning systems offer a perfectly clean beam, without stray light, allowing for maximum creative precision and light and shadow control. In film, broadcast and photography, dedolights have become part of the standard arsenal of the world’s most discerning professionals.

From the smallest productions to Hollywood blockbusters, dedolights are the first (and often the only) choice of lighting when demanding the highest possible precision and control, for example in special effects (as seen in Harry Potter, Lord of the Rings, Armageddon, and many more films). dedolight has a long history of award-winning lighting systems, winning two Oscars in 1990 and 2003, an Emmy in 2003 and Cinec awards in 2002 and 2010.

Museums have used modified dedolight systems for over twenty years. Recognising the unique demands of museum lighting, the dedolight research and development team designed the latest series of dedolight precision lighting systems especially for these applications. Extreme care and latest state-of-the-art technology guarantees light distribution and light character, efficiency and color rendition, regardless whether the light sources are halogen, metal halide or LED. dedolight are industry leaders in offering the world’s first asymmetric focusing light, and, for the last 15 years, providing the world’s lowest ultraviolet values.


dedolight precision lighting instruments have supplied professional lighting equipment to the film and broadcast industry for over a quarter of a century. Recognising their superior quality, museums began to adapt dedolight equipment for their own specialised use. Seeing this, Dedo Weigert Film (DWF) responded by creating a dedicated range of lights for exhibition and heritage use, the DLAD classic. A new series of dedolight architectural lighting system was introduced 2010, called DLAD II, and in 2014 the DLADL was added to the portfolio. From the ancient wonders of Egypt to the United States Bill of Rights, many of the world’s greatest treasures are lit by dedolights. We have been involved in projects across a wide range of industries and arts, all designed to bring out the best in art, artefacts and interiors across the globe.
