Powerful software

For all our LED lighting products, we provide the possibility of easy and fast firmware updates.
With each update, the software of the Orbiter becomes even more user-friendly and customizable. Download the latest version below.

Once again ARRI has given us another powerful light to add to our tool bag. The Orbiter will replace several tools. The Orbiter’s real innovation is in the software. The many different modes and especially the x/y mode make this an extremely useful light.

02 Optics Auto Adjust_NEU
Optics Auto Adjust—100% color stability

The Optics Auto Adjust Mode offers 100% color stability with any optic and any focus. Utilizing the accessory recognition of Orbiter’s innovative QLM (Quick Lighting Mount), the ARRI Spectra light engine is modified to maintain maximum color stability no matter which configuration is used; this includes textiles such as Softboxes or Domes, a reflector in Open Face, or lenses such as the new Orbiter Fresnel Lens. Also, with Orbiter's new Fresnel Lens, LiOS2 ensures the color rendition across its entire zoom range. This gives the camera crew time to focus on other important settings.

03 8colors modes
8 color modes with plenty of extras

LiOS provides a total choice of eight color modes, including CCT, HSI, direct LED control, X/Y, gel, source matching, and effects. On top of that, the extended color control (ECC) allows fine-tuning to the smallest detail. The color sensor mode is now accessible directly from certain color modes like CCT or HSI and can also be integrated into favorites and cues.

04 Sync-Mode_NEU
Sync Mode—lights on when the camera needs them

Time matters on every production, and with the LiOS2 Sync Mode, light output can be triggered when and how the camera needs it. This LiOS2 automation is designed to free up the crew for real teamwork. Sync Mode allows the lighting parameters to be enabled or changed in sync with the camera frames. Even frame brightness or CCT range can be changed to accommodate new creative ideas.

05 Cue Mode_NEU
Cue Mode—for precise lighting control right on the spot

Exact timing is key for capturing dynamic images and Cue Mode enables precise lighting control right on the spot. Every operator can set the key lighting parameter right on time and with precision. Besides variable timing and working options, the new Cue Mode even allows for fluid and easy light changes in different lighting modes. The transition can be selected from five different options, already known from SkyPanel.

06 Additional languages
Additional languages—your mother tongue for intuitive working

At ARRI we believe that communication is key and the preference for one's native language is universal. What is easier than communicating in your mother tongue? The new additional language package supports Portuguese, Japanese, and Korean. Now even more crew members around the world can have an easier time operating Orbiter.

Now, there is a total of eight language options available: English, Chinese, Spanish, French, German, Portuguese, Japanese, and Korean. More to come.

07 Gel library_NEU
Gel library extension

The building blocks of Orbiter are more advanced and capable than any other ARRI light. ARRI Spectra, Orbiter's six color light engine, can now translate even more colors and nuances. Extending the gel library with LiOS2 maintains our commitment to Orbiter’s mighty set of features and options. LiOS2 offers now more than 170 additional gels.

08 Smooth way_ambient light_NEU
Smooth way to adapt ambient light

The values of the integrated color sensor in Orbiter can now directly be selected from within color modes like CCT or HSI in LiOS2. The matching of ambient light has never been easier, allowing for final manual adjustment if needed.

09 Fully Customizable_NEU
Fully customizable

Various choices of operational modes and settings allow Orbiter to adapt to any possible demand and application. Choices include light quality and fan mode settings, as well as dimmer curves and transition types. Tungsten emulation, flicker-free high-speed mode, and the option to use external triggers are also on board.

Network options


You can set one Orbiter as a Host to control other multiple Client Orbiters. Clients will simply mimic all controlled actions made on the Host Orbiter. DMX and RDM are their communicating language.


Network options

Streaming ACN

With the implementation of sACN, the Orbiter now supports all industry standard lighting control protocols. This makes the Orbiter even more flexible and allows for integration into additional control environments. 

Network options

DMX/RDM Gateway function

Any Orbiter can now act as a transformer from Input Ethernet based control protocols such as ArtNet and Streaming ACN (sACN) towards output of 5 Pin DMX for daisy chaining of multiple units. RDM messages are being sent and received bi-directional as well. This eliminates the need for external or third-party devices for control protocol conversion. Further, the new DMX Mode Spec V5 allows for more convenient network operation and additional features within the LiOS2 update. For example, the zoom range of the Orbiter Fresnel lens can be operated, allowing for Extended Color Control (ECC) to be directly available. Of course, all elements are also addressable via RDM.

Network options

Orbiter’s digital communication

To make Orbiter’s digital communication and its protocols straight forward the support of various RDM PIDs, Art-Net Messages such as ArtipProg and ArtSync have been added as well as various improvements for the integrated webpage control option.
