Generating an ultra-tight 4° beam from each of the 18 pixels, they combine to produce a bright, defined “sheet” of light, desired by Lighting Designers. Seamless curtains of light can be constructed using several fixtures as the detailed design allows any combination of TETRA1™ and TETRA2™ to be placed end to end on stage or truss, whilst maintaining equal spacing between pixels. With the addition of two exclusive Robe patented MCFE™ – Multi-Coloured Flower Effects, the pixel-driven Tetra1 sets itself apart from others by projecting charismatic in- air animations.

The homogenised beams, together with the smooth 11:1 zoom, provide; a wash out to 45°, a footlight, a wall graze or dynamic in-air effects with fast paced sweeping movements. Utilizing our latest L3™ (Low Light Linearity) dimming system for an imperceptible fade to black, the 18-bit control provides ultra-smooth colour mixing across the full colour spectrum. An embedded Ethernet switch and wide range of protocols (sACN, Art-Net or Kling-Net) allow a quick network installation and ease of control from media servers, DMX or the internal effects engine.

Innovations

RLCT™ – Robe lens coating technology

Just like with spectacles, our lens coating technology protects soft plastic lenses against surface scratches, that can even occur during cleaning when scrubbed repeatedly. Anti-static properties prevent dust build-up on the lenses, thus extending the period between maintenance cleaning.

DataSwatch™ – inbuilt virtual colour library

The DataSwatch™ inbuilt virtual colour library for Robe LED fixtures provides consistent colour rendering with commonly matched filter ranges, allowing for rapid and accurate programming.

MCFE™ – Multi Coloured Flower Effect

The Robe patented MCFE™ – Multi-Coloured Flower Effect – creates sharp, multi-coloured spikes of light, that are fully rotatable in both directions, at variable speeds.

Tungsten Emulation

When selected, the luminaire will mimic the colour temperature of a tungsten lamp as you lower the output to produce that classic warm glow.

L3™ – Low Light Linearity System

The L3™ Low Light Linearity System produces imperceptible, ultra-smooth fades to black.

REAP™ – Robe Ethernet Access Portal

The Robe Ethernet Access Portal allows to access internal data from a networked fixture, viewed as a web page, addressable via the fixtures network IP.

GDTF – General Device Type Format

The General Device Type Format creates a unified definition for exchange of data for the operation of intelligent luminaries, such as moving lights. The file format is human readable and developed using open source formats.

QVGA Robe Touch Screen Display System

The QVGA Robe touch screen display gives full access to all fixture setup and diagnostic functions and is very intuitive to navigate.
