Dedolight focusing systems are famous in part thanks to very efficient front optics with micro-lensing that homogenize the beams. The DLED7N-C Neo multicolor focusing light also features this proven front lensing resulting in a homogenous beam in most situations. Even so, slight color fringing might occur when set at specific white light ranges, especially in combination with the focus set to tight spot. To combat this possible effect, DLEDN7-C fixtures are delivered with a DFOPTC drop-in Optimizer: a filter to further coalesce the diodes output when the fixture is set in white CCT ranges. Specifically, it enhances the cleanliness of white color blending on the subject and eliminates residual fringing in the transition to shadows.
Why additional blending?
Without white LED diodes in its cob, the DLED7N-C uses six different color diodes to output a very broad CCT range between 1800K - 20,000K (including the most used between 2700K and 6400K). Of course this results in less output in the white ranges than a mono-color, or even a bi-color light (1.5 stop less). That said, having this broad spectrum of white light capability from a six-color light has technical and creative advantages. For example, the Prolycht Hyperlight multicolor engine in the new DLED7N-C Dedolight Neo eliminates the gaps in spectrum found in other current LED technologies.
THE DFOPTC & THE DPBA-714 BEAM INTENSIFIER
The DFOPTC filter consumes approximately half of the light's output. If you want to have all the output back, and more, use it in conjunction with a DPBA-714 Beam Intensifier.
At 10 ft, set at 5600K, the DLED7N-C, together with a DFOPTC Optimizer and DPBA-714 intensifier outputs 245 fc in a fixed 11º spot. In addition, the beam becomes approximately 5° tighter and 275% BRIGHTER than the light's native super-spot angle. This extremely powerful output and tight beam angle are well beyond what any other 80W multicolor light achieves.
A PLUS FOR LIGHTSTREAM USERS
Lightstream reflectors do the work of blending light upon reflection. The DLED7N-C can be used with the DPBA-714 without the DFOPTC optimizer for this purpose. Check-out the raw power of the Neo multicolor set at 5600K with the DPBA-714 (and no Optimizer): 525 fc at 10ft, in a 7º Super-spot beam. Now bounce this powerful beam on a Lightstream reflector to take advantage of the technical and creative qualities this setup offers (recommended with the #2, #3, #4 Reflectors).
NOTE: Each DLED7N-C+ light set purchase includes one DFOPTC unit. For maximum output, use the dull side of the filter towards the set.
