Robert Juliat’s eagerly awaited answer in the multicolour LED profile market comes in the shape of the Bizet 8C 780SX. Featuring a 540 W engine combining eight LED colours, onboard colour management and a conversion option for existing 700SX profiles, the French manufacturer has several arguments to win over theatres and rental companies.
Deep red, red, amber, yellow, green, cyan, sky blue and royal blue: Robert Juliat uses eight components to broaden the palette of its new profile. This architecture, for which a patent application has been filed, aims to combine rich colours with high-quality whites.
The manufacturer specifies a CRI above 98 and light output equivalent to a traditional 2 kW tungsten profile. The Bizet 8C comes with three zoom ranges: 11°–26°, 16°–35° and 28°–54°. Its reportedly completely silent operation is another selling point for theatre stages and venues where fixture noise remains a major concern.
Eight colours, several ways to control them
To make full use of this engine without requiring the console operator to control its eight components individually, Robert Juliat relies on RJ Color, its onboard control system, which processes all data in real time to achieve any desired shade, regardless of the console used.
The Bizet 8C can also be controlled using CIE xy coordinates, Hue Saturation, RGB, or direct access to the emitters in RAW mode. In RGB mode, users can select the fixture’s native colour space or work in sRGB, Rec.709, Rec.2020 and ProPhoto. Two colour-mixing optimisation modes, High Quality (HQ) and High Brightness (HB), also allow users to prioritise colour quality or output.
For whites, three calibrated presets simulate tungsten sources at 3,000 and 3,200 K and a discharge source at 6,500 K. Delta UV adjustment allows fine-tuning along the green–magenta axis.
Filters and tungsten behaviour
The onboard library contains 300 calibrated colour filters, with adjustable transmission and saturation. The duration and type of transition between two filters can also be set. The DimShift function changes the colour temperature during dimming to reproduce the warm shift of a tungsten source along the Planckian locus. It is available for calibrated whites, different colour temperature settings and colour filters.
For simpler applications, a single-parameter DMX mode allows a colour or filter to be selected locally on the fixture, leaving only intensity to be controlled from the console, with 8-bit or 16-bit resolution. Compatible with DMX, RDM, Art-Net and sACN, the Bizet 8C allows all control parameters to be configured via RDM or a web interface. It also incorporates advanced Ethernet node features, supporting RDM, LLRP and Zeroconf.
A new light engine for the 700SX
Finally, Robert Juliat offers this eight-colour engine as a conversion module for 700SX profiles. This is a particularly interesting prospect for venues already equipped with these fixtures, allowing them to consider an upgrade to multicolour LED while retaining part of their existing equipment. By combining a new fixture with an upgrade path for installed units, the manufacturer gives its eagerly awaited response a scope extending beyond a straightforward addition to its catalogue.
