 Cu-Beam Duo light on black

Technology

Ricochet™ technology. Power, without waste.

Ricochet™ technology uses one-touch shutters and a reflective surface, to convert unused down-light into usable, useful up-light. Not one lumen goes to waste.

Cu-Beam Duo light electronics

Fully flexible light. Up and down.

The custom driver controls the split and strength of light, so the Cu-Beam Duo light can adapt to different tasks throughout the working day. And night.

Cu-Beam Duo light distribution animation

Heat pipe technology maintains LED brightness.

Six vacuum-sealed copper tubes transfer heat away from the LEDs. The single drop of water in each evaporates with the heat from the bulbs, before the 37 cooling fins help it condense. This continuous cooling cycle increases the single LED's longevity.

Exploded view of Dyson Cu-Beam Duo light
Cu-Beam Duo - Two custom lenses

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

The custom-engineered lenses optimize the output of two high-power LEDs. With a 50/50 split, the up-light projects 9400 fixture lumens and 733lx of even, ambient light. Down-light delivers 9400 fixture lumens and 722lx of focused, shadow-free illumination.

Close-up of custom-built driver

Custom-built driver for full control. Engineered from scratch.

Our engineers designed the onboard driver for precise control of all the light's functions. Three printed circuit boards (PCBs) enable multiple communications through the transmission wires. They manage power, voltage fluctuations and the ratio of up and down-light.
