Key features

Dyson Cu-beam Duo light.

Maximum efficiency. Minimum waste.

Ricochet™ technology uses one-touch shutters and a reflective surface, to convert unused down-light into usable, useful up-light. Combined with the efficiency of Heat pipe technology, no light – or power – goes to waste.

Fully flexible light. Up and down.

A custom-built driver controls the direction, dimming and ratio of powerful up and down-light. From a wide pool for presentations, to a focused pyramid on work surfaces, Cu-Beam Duo light covers any task, at any time.

Key technology

Heat pipe technology maintains LED brightness

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

Two custom lenses focus 9400 lumens. From just 2 LEDs.

The custom-engineered lenses optimize the output of two high-power LEDs.

High efficacy

Heat pipe technology effectively cools the Cu-Beam Duo light, so it can run at 107lm/w (3000K) / 113lm/w (4000K).

Additional features

Fluorescent lighting is flawed, LEDs can be misused

Commercial lighting largely relies on inefficient, costly fluorescent bulbs or the ineffective use of multiple LEDs. Cu-Beam Duo ensures no light is wasted, providing effective up and down light.

Powerful up and down-lighting

Combined, the two high-power LEDs can project 9400 lumens at 4000K. Heat pipe technology cools the LEDs to optimize longevity, without loss of brightness.

Controlled pyramid of down-light

When mounted at 4.3 ft (1.3 m) above the task area, the down-light projects up to 722 lx at 4000K evenly over an area of 10.5 ft x 5.3 ft (3.2 m x 1.6 m).²

Glare and flicker control

One-touch shutters hide glare from users. Line of sight and reduce glare to below 1%.

Light, precisely where you need it

Two custom-engineered lenses and adjustable one-touch shutters precisely focus the two high-power LEDs.

Wide distribution of up-light

Suspended at 15.8in (400mm) from the ceiling, the up-light illuminates evenly over an area of 13ft (4m).²
