Here, the many different focusing versions of dedolight come into play. The reasons can
be seen in the following: the dedolight optical concept works with two different lenses which are non-spherical.

Also, there are different movements and travels of these elements in relation to the light source; and in some of the original lights also including the reflector.

With this system, which was twice recognized by the Oscar Committee of the Academy of Motion Picture Arts and Sciences we were able to achieve an unprecedented focus range.

Traditional small-sized Fresnel lights usually show a focus range of 1:3, the biggest ones can perform a focus range of 1:6.

Already the smallest original classic dedolight provides a focus range of 1:25.

Beyond that, the carefully designed dual non-spherical system creates perfectly smooth
light distribution all the way across the beam from edge to edge, whilst practically every Fresnel delivers a hot spot in the center, or — in flood position a brighter aura on the edge.•

Thus, we are able to achieve a perfectly homogenous beam with the focusing dedolights,
maintained all the way through the focus range from widest flood to narrowest spot.

At the same time we provide a beam that is clean and does not involve a lot of stray light. We call this the 'Clean-beam Concept'. Thus, we are able to achieve also a very narrow beam with far reach, which on its own can contribute to the world of reflected light.

Beyond that, the discharge lamps in some of the dedolight focusing lights provide something unique — they also provide even and smooth color distribution edge to edge, which is not common with other focusing lights which usually show with a discharge light source a bluish rim in the flood position, towards the edge of the illuminated area.

Thus, we have already taken a big step towards the efficiency of the dedolight Lightstream system.

The biggest step comes with the new seemingly miraculous front-end attachments for all of the focusing dedolight systems — we call this the Parallel Beam Intensifier.

For example, let us look at the DLH400.
A 400/575 Watt metal halide fixture with a basic focus range of 1:20, provided by the dual aspherical optics and a triple zoom focus motion, all operated by one single button.

This light provides an absolutely clean color, not quite common for metal halide light sources; and it maintains this quality throughout its lifetime.

In the spot position it provides a 4 degree exit angle and therefore has a very far reach, and can be placed at a considerable distance, already on its own contributing a major step towards the efficiency of the dedolight Lightstream system, the world of reflected light

Now we add the new and surprising parallel beam intensifier DPBA1419. And all of a sudden we increase the light output by an additional 500%.
Sounds absolutely unbelievable, but can be proven anytime. You just need your light meter / lux
meter.

By performing this seeming miracle we don't really change the exit angle of the light much, it remains pretty close to the 4 degree original exit, but the drastically enhanced output makes it eminently suitable for the dedolight Lightstream system.

We have such attachments for each and every one of our dedolight focusing light fixtures, from the 1200W metal halide system through all of our LED systems, all the way down to the tiniest light, the Ledzilla light which works with an 8W LED light source and can also start to spit fire once you add the DPBA70 parallel beam intensifier.
