Key features

Illustrating light path of Dyson Cu-Beam down over desks

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.

Flourescent lighting in commercial setting

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

Surpasses office lighting standards

Distributes up to 674lx (at 4000K) evenly over an area of 10.5ft x 5.3ft (3.2m x 1.6m) when mounted at 4.3ft (1.3m) above the task area.
