Custom LED Balls: From Simple Glow to High-Density Pixel Mapping

We’re frequently asked to design and manufacture LED balls for film and television productions. On the surface, they may seem straightforward — a glowing sphere — but in reality, they can range from simple single-colour emitters to highly complex, pixel-mapped lighting systems.
Every LED ball we create is driven by the specific needs of the production.
Design Considerations
Several factors influence the final design:
Required brightness and output level
Surface area coverage
Serviceability and access
Single colour, bi-colour, or full pixel control
Self-powered or externally powered operation
Wired or wireless communication
While the concept is simple — producing light evenly across a spherical surface — the engineering challenge lies in converting fundamentally flat electronics into a seamless, three-dimensional form.
It’s a technical puzzle we genuinely enjoy solving.
Sizes & Configurations
Over the years, we’ve developed LED balls ranging from 30mm to 300mm in diameter, available in:
Single colour
Bi-colour
Fully pixelated RGB systems
As sphere size increases, so does system complexity. Large pixelated balls can require significant data bandwidth — sometimes 4, 5, or even up to 8 DMX universes — to manage individual pixel control across the entire surface.
To support this, we also develop and integrate appropriate wireless communication systems to ensure stable, high-speed control in real-world production environments.
High-Density Flexible PCB Construction
The example shown here features a flexible PCB design that wraps seamlessly into a spherical form.
This particular ball:
Measures just 60mm in diameter
Contains over 500 individual LEDs
Offers high-resolution pixel mapping
Supports real-time control via Wi-Fi
By using very small pixel spacing on a flexible circuit, we achieve impressive definition across a compact spherical surface.
Lighting for Visual Effects Integration
One of the most powerful applications for pixelated LED balls is in visual effects workflows.
In many cases, the audience will never see the physical ball itself. Instead, it acts as a dynamic, interactive light source for something that will be added later in post-production.
For example, if a glowing “ghost” or energy form is to be added in CG:
The LED ball is used on set as the practical light source
It casts accurate, real-time lighting onto actors and surfaces
Pixel mapping allows dynamic, animated light changes
The CG element replaces the physical ball in post
This approach delivers realistic interactive lighting on set and significantly reduces the need for complex CG lighting simulations later.
The result:
More believable interaction between characters and environments
Reduced post-production time
Lower CG costs
Greater creative control during filming
Practical, Programmable & Production-Ready
Whether the requirement is a simple glowing orb or a high-channel-count pixel-mapped sphere with wireless control, we tailor every build to suit the production’s creative and technical needs.
From compact 60mm high-density designs to large multi-universe spheres, our LED balls combine robust engineering with flexible control — enabling filmmakers to bring light-based effects to life directly on set.
If you have a spherical lighting challenge in mind, we’d be delighted to explore what’s possible.
