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 replacement bulbs can be costly, while LEDs can suffer from overheating, affecting their longevity and brightness.

Key technology

  • Heat pipe technology maintains LED brightness

    Cools the LED to sustain brightness for up to 180,000 hours.¹

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

    The custom-engineered lens maximizes the single high-power LED, for powerful illumination, 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 aluminum fins, so it weighs just 2.9kg, or 6.4lbs.

  • 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 LED and a custom-engineered lens provide powerful light that can illuminate a wide area.

  • Compact and lightweight

    Cu-Beam Up measures 28.3 in (720 mm) across, weighing just 2.9kg, or 6.4lbs. The unit 'floats' in space for minimal spatial intrusion.
