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.
