DPB70 is the largest, most powerful of the Dedolight parallel beam lights, mainly directed at use in Lightstream, for the appearance of a natural light source.
THE DPB70 IS A SPECIAL, PROFESSIONAL LIGHTING FIXTURE, PROVIDING A POWERFUL PARALLEL BEAM
The DPB70 is the largest and most powerful of the parallel beam lights, mainly directed at the use in Lightstream Drama applications. Beam projectors have been known in our industry, but this one is different, as much as it offers a very defined beam, and at the same time a homogenous light distribution all across the beam.
The beam has an exit diameter of 70cm, 27.5 inches. This parallel beam light fixture can be used for the appearance of a natural light source, being far away by virtue of its character, and its over-ruling of the square law. For this reason, this light fixture has already been chosen for some major film projects to simulate sunlight because of its natural and unique character.
When operating this light fixture with reflectors, there is a choice of the largest reflector that we currently provide, using a 100 x 100 cm reflector surface (usually the # 1 type) to redirect the light in an opportune direction, without much change to the beam diameter and the beam character, and without causing much noticeable stray light. Especially, when such a large reflector, redirecting the entirety of the beam, is used, the result is a virtual light source at considerable distance. Thus, talent/actors are able to move in the reflected light, without diminishing light intensity when changing position.
This lighting instrument can therefore be used with a large reflector to redirect the light beam in its entirety, or can be used with a multitude of smaller reflectors, to direct parts of the beam in different angles and directions.
Often, a multitude of reflectors is used for secondary and third reflectors, to change the direction of the light, to change the character of the reflected light, and thus, lighting entire scenes from a single light source. The side effect of such lighting practice is to eliminate a lot of lighting paraphernalia from the set without cluttering the set with many fixtures, lighting stands, flags and other instruments.
Sometimes the entire diameter of the parallel beam gets redirected by a large reflector (1×1 meter), no. 1 type.
Other times, several smaller reflectors share the beam to redirect the light simultaneously to several directions and further reflectors.
The deeper you insert the reflector into the beam, the more light becomes active. Thus, you choose a level of intensity without changing color or character. (You could call this: opto-mechanical dimming)
The Lightstream beam light and reflector systems’ great achievement consists in the fact that we achieve all this without altering the color quality or character of the initial light.
The DPB70 light is powered by the dedolight DEB1200D flicker-free ballast, which also allows dimming of the light source up to 40% and operates quietly and can be controlled by DMX signals.
The DPB70 is rainproof and therefore suitable for lighting setups in exterior and continuous use, even under adverse conditions.
The beam can further be cleaned from remaining parasitic light by adding a honeycomb, which reduces the light output only minimally.
A filter holder can be added for total or partial filtering with gel filters.
A transport case is available (Code: DCHD70, Euro 930) to receive the light head, as well as the ballast or necessary cabling, and three sets of reflectors, as well as a choice of mounting/grip equipment.
Less equipment, more lighting precision
Lightstream by Dedolight is a system using reflectors and parallel beam lighting, that makes the quality of the light and shadows become uniquely realistic. The high efficiency of these reflectors within this system derives from reflective values, where approximately 95-98% of the light can be effectively reflected.

Interview lighting with Dedolight Lightstream reflectors
Pete Burns, lighting cameraman from the UK, introduces and explains his interview lighting kit, which is based on parallel light intensifiers and handy Dedolight Lightstream reflectors.
The Miracles of Parallel Light for the Lightstream Practice
The practice is as old as image creation. Everyone of us has used reflectors. The key and the gate opener to the system is obviously light. Could be the sun, but then, with no sun available, the best results can be reached with parallel light. Our particular pride though is in the evolution of dedolight optical systems, which now culminate in the added parallel beam intensifier for all of our 21 different focusing dedolights.
Om reflektor #1-4
The high efficiency of these reflectors within this system derives from reflective values, where approximately 95-98% of the light can be effectively reflected. When used with Dedolight Parallel Beam Attachments the quality of the light and shadows become uniquely realistic.
Lightstream use four different reflector types, each featuring a different reflecting surface.
On the one hand, the characteristics of the different reflector surfaces play an important role between the hard, narrow exit angle from reflector #1, which is the one to “redirect” light, whilst #2, #3 and #4 is reflectors, because they have a larger exit angle.
Reflector #1 serves the purpose of redirecting the light without changing the beam size and the beam character. The attempt here is to cause a minimum of stray light and a minimum of diffusion. This surface structure provides reflection with an exit angle of about 4°. Reflector #1 is the closest to a very hard reflector and can easily be confused with known mirror reflectors, which don’t have the same characteristics, they indeed sometimes produce spotty and uneven light.
Reflector #2 shows less light intensity at the object, although the total amount of reflected light remains pretty much identical with 95-98%, but due to the wider exit angle of 12°, it makes it more suitable when we want to arrive in the next reflection from the secondary reflector with a larger surface.
Reflector #3 appears to be much gentler, although again the same amount of light gets reflected, but spread over an angle of 50°.
Reflector #4 produces seemingly the most gentle reflection, covers an angle of 95°, and thus, lower values of light level reaching the object, and the virtual light source now, coming very close to the reflector surface, only 4 cm behind the reflector.
