Dedolight parallel beam forsats-linse (DPBA-BI7) for DLED4-BI & DLED7-BI
3 040 kr (ekskl. mva)
Boost the output of your existing light fixture with Dedolight Parallel Beam Attachment for Dedolight LED fixtures with 7cm diameter, fits DLED4-BI & DLED7-BI.
Dedolight Parallel Beam Attachments both boost the output of the light fixture and create a virtual light source distance; this provides a quality of atmospheric realism and shape.
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.
Dedolight DLH400DT HMI in the Lightstream system
Watch how the DLH400DT can be used to focus the HMI light into reflectors, with a Parallel Beam Intensifier. This is a lens specifically designed to focus the light to achieve more than 500% increase in light output.

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.
