Is that what it really looks like?

Yes. This is the sphere at Mahalla in 2025, filmed as it is.

The real thingMahalla, 2025Original footage, 12-second loop100 cm prototype with superseded LEDs: each pixel is seven LEDs wide, with no warm white. HELIO now uses 144 LEDs per metre, every LED its own pixel, in RGB plus warm white.

How does one ring fill the sphere?

Reflections give it depth

The ring repeats inside the shell, so one line of light reads as many.

Colour that moves

Hold one calm colour for a room, or let it run for a crowd.

What can it play?

How do you control it?

From the HELIO app over Bluetooth or Wi-Fi, or from the show desk over the network.

  • HELIO app in light mode: a HELIO sphere with its preview, master brightness and the first scenes
    Try the app, simulated (light mode)
  • Its preview, playing (dark mode)

At home

  • Bluetooth or Wi-Fi control from the HELIO app
  • Wi-Fi setup from the phone
  • 34 factory scenes, with static and audio playlists
  • A microphone for sound to light, a light sensor for automatic brightness
  • Home Assistant and MQTT for your smart home

At events

  • Art-Net, E1.31 and DDP input from Resolume, Madrix and xLights
  • OSC from TouchDesigner and TouchOSC, and MIDI desks
  • xLights show playback

HELIO runs on the open-source MoonLight firmware, which brings Art-Net, E1.31, DDP, OSC, MIDI, xLights playback, Home Assistant and MQTT. The HELIO app, its Bluetooth control, the scenes, the sensors and signed firmware updates are ours. The network protocols are being qualified on HELIO hardware; tell us your setup and we confirm it for your show. The HELIO app is in testing for iOS and Android.

Can it stand at a festival?

Yes, on a light stand.

A half-circle metal yoke holds the sphere at its flange and screws onto any light stand with an M10 thread, such as the Gravity LS 431 B.

Ask for the stand option in your event enquiry.

About the model and mounting concepts

Model reference
The supplier drawing specifies a 700 mm dome and a 740 mm flange. The original HELIO simulator traces light reflecting inside the sphere. The surroundings and mountings are visual concepts.

Floor concept
A semicircular yoke holds two locking pivots. Proposed protected metal adapters connect these to the equatorial flange and spread the load.

Physical configuration
The final adapter, assembled weight and support system need verification before installation.

Assembled weight, electrical requirements, mounting and outdoor suitability, and fire classification (including B1) are not yet verified for the complete product. These must be assessed for your intended use as part of an individual offer.
