Following 892 prototypes over a two-year period, Dyson has launched its Lightcycle task light, which continually adjusts its colour temperature and brightness in relation to the local daylight conditions. 

The light uses a time, date and location-driven algorithm to calculate the colour temperature and brightness of daylight, anywhere in the world. To do this, the light uses data from over a million satellite-based measurements of light conditions in the earth’s atmosphere.

Lightcycle continually interprets this daylight data, communicating it to the optical driver embedded in the product for dynamic colour tuning. The light has three warm and three cool LEDs that work in tandem to simulate daylight colour temperatures. In addition, it is designed to minimise flicker and glare to protect against eye strain and visual fatigue.

The light also uses technology commonly found in satellites to protect the LEDs from overheating which can cause fading and discolouration. A vacuum-sealed copper tube draws heat away and inside, a drop of water evaporates, dissipating heat along the pipe as it condenses, before returning to the LEDs, providing a non-stop, energy-free cooling cycle. This can help maintain the brightness and light quality of the LEDs for up to 60 years.

Users can also personalise the light thanks to the Dyson Link app, which continually communicates with the Lightcyle to adjust light output for your age, task, daily routine and local daylight – designed to support optimal illumination throughout the day.

There are seven pre-set modes: Study, Relax, Precision, Boost, Wake-up, Sleep and Away, as well as manual control with slide-touch dimming and colour temperature selection that lets you define your personal light preferences. It’s possible to pre-programme and assign names for up to 20 different light settings, to suit your task or mood.
