Products & Technical

What is fiber optic lighting?
Fiber optic lighting is a system that generates light from an LED engine (light source) and transmits it through thin fiber optic cables to the desired point. It is widely used in starlight ceiling, pool lighting, decorative and architectural applications.
What is the difference between PMMA fiber optic cable and glass fiber?
PMMA (polymethyl methacrylate) cables are flexible, lightweight and easy to shape. They are ideal for decorative lighting. Glass fiber has higher light transmission capacity but is fragile and preferred for industrial applications.
Which LED engine is suitable for my project?
Different LED engines are available depending on your project size and desired effects. Single-color engines for small rooms, multi-output RGB engines for large areas, and DMX-controlled engines for special effects. You can find the right engine on our device selector page.
How do I calculate fiber optic cable length?
Determine your ceiling area (m²), then choose your desired star density. An average bedroom needs 150-250 points, large rooms 300-500 points. Calculate ceiling height + 50cm spare for each point.
What is the difference between pixel LED and fiber optic?
Pixel LED are addressable LED strips where each LED can be individually programmed. Fiber optic distributes light from a central source. Pixel LED offers brighter and programmable effects, while fiber optic provides a thinner and more elegant look.
