Key features

Dyson Cu-Beam Down light with targeted pyramid of light on boardroom table

Fully-adjustable down-light, precisely where you need it.

Focuses a single light source to create a targeted pyramid of dimmable down-light.

Fluorescent lighting is flawed. LEDs can underperform.

Commercial lighting largely relies on inefficent, costly fluorescent bulbs or the ineffective use of multiple LEDs. The Cu-Beam Down light provides focused light.

Inefficient, costly fluorescent bulbs on office ceiling

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 5350 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 94lm/W (at 4000K)

Additional features

  • No glare

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

  • No flicker

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

  • More light

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

  • Powerful down-lighting

    A single LED projects 5350 fixture lumens (at 4000K). Heat pipe technology keeps the LED cool to sustain its brightness for up to 180,000 hours.¹

  • Compact and lightweight

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

  • Surpasses office lighting standards

    Distributes 674 lx (at 4000K) evenly over an area of 3.2m x 1.6m, when mounted at 1.3m above the task area.
