TETRA1 is a linear bar built on the highly successful Spiider and Tarrantula technology. Despite its shorter length, TETRA1 maintains the same features, quality and pixel spacing as TETRA2.

Generating an ultra-tight 4° beam from each of the 9 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 compact, 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 one exclusive Robe patented MCFE™ – Multi-Coloured Flower Effect, 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.

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. They consist of up to 237 pre-programmed and calibrated colours and tones.

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. The effect is implemented into various Robe fixtures, operating in one or more of their pixels. If the MCFE™ is not in use, the pixels become regular RGBW pixels with identical output to their neighbours.

L3™ – Low Light Linearity System

The L3™ Low Light Linearity System produces imperceptible, ultra-smooth fades to black. By super-refining the internal dimmer curve to 18 bit and removing the pitfalls of “steppy” LED dimming, we facilitate the total integration of LED fixtures with existing, traditional, light sources.

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. The portal provides full access to all the fixture's addressing, set-up and diagnostic functions, even when in DMX mode. This saves preparation time, allowing identification of the luminaire in the rig, as well as all diagnostic functions, without physical access to the luminaire.While the REAP™ interface doesn't replace multi-device automation workflow based on RDM, it provides a very convenient way of viewing and adjusting personality settings, with some icing on the cake like DMX capture, to see real DMX data as received by the device.

Robe lens coating technology

The innovative Robe lens coating technology brings benefits, including longer intervals between cleaning, bright and clean lenses, no scratches or marks, and higher light output.

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. This results in a brighter, cleaner, easier to maintain fixture.

GDTF – General Device Type Format


The General Device Type Format was conceived and jointly developed by the GDTF development group, comprised of Vectorworks, MA Lighting, and Robe lighting. It creates a unified definition for the exchange of data for the operation of intelligent luminaries, such as moving lights, officially recognized as an open standard for the entertainment industry worldwide by DIN SPEC 15800. 

It provides a dependable way to adapt fixtures and devices in the lighting industry and sets a manufacturer-supported, unified standard. Therefore, customers/users of lighting control systems, CAD systems, and pre-visualizers benefit by knowing the tools they use to perform their job will work consistently and dependably. 

The file format is human readable and developed using open source formats. Luminaire manufacturers in the entertainment design, production, and performance industries are welcome to use this open-source technology. 

Tungsten Emulation

"Red shift" or "amber drift" is the warming of colour temperature produced when you dim a tungsten lamp. This can be replicated with Robe fixtures with additive colour mixing LEDs, such as Multichip LEDs or MSL™, using our Tungsten emulation technology. When selected, the luminaire will mimic the colour temperature of a tungsten lamp as you lower the output to produce that classic warm glow. You can even decide the wattage you wish to emulate, such as a 750W, 1.000W, 1.200W, 2.000W and 2.500W lamp. This allows for seamless integration with traditional generic fixtures.

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. It comes with battery backup for settings such as an address, even when the fixture is not connected to power, saving a lot of preparation time! It is equipped with a gyroscopic gravitation sensor for auto screen positioning, meaning it will always display the right way up, whether standing or being upside down in a flight case. Furthermore, it has an operation memory service log with RTC, stand-alone operation with editable programs and a built-in analyser for easy fault finding.
