Key features

Dyson Cu-beam Up light above sofas in an office lobby.

Powerful, fully-adjustable up-light. From a single fixture.

Focuses a single light source to evenly cast an ultra-wide, dimmable pool of ambient up-light across open spaces.

Fluorescent lighting is flawed. LEDs can underperform.

Fluorescent lighting can be inefficient, it wastes light and uses costly-to-replace bulbs, while LEDs can suffer from overheating, affecting their longevity and brightness.

Key technology

  • Heat pipe technology maintains LED brightness

    Continuous cooling cycle increases the single LED's longevity with no loss or deterioration of light quality.

  • A custom lens focuses 7800 lumens. From one LED.

    The custom-engineered lens optimises and maximises the single high-power LED, for an even spread of powerful, ambient light, whatever the task.

  • High efficacy

    A custom-engineered lens combined with effective cooling means that each fixture runs at 92lm/W (at 4000K).

Additional features

  • Brightness means lightness

    Each wing of the Cu-Beam Up light is made of 37 lightweight aluminium fins, so it weighs just 2.9kg.

  • No glare

    By putting light precisely where it needs to be, Cu-Beam Up lights prevent wasted light in all directions and reduce eye strain.

  • No flicker

    Custom-built drivers control the light's functions. They manage power, voltage fluctuations and the ratio of up light.

  • More light

    High-power single LEDs and a custom-engineered lens provide powerful light that can illuminate a wide area.

  • Compact and lightweight

    Cu-Beam Up measures 720mm across, weighing just 2.9kg. The unit 'floats' in space for minimal spatial intrusion.
