Free-standing LED luminaire with swarmControl

SFERA's purist design and premium materials create office accents.
The light-weight and transparent look of the luminaire head emphasises the contemporary design of SFERA.

Design: Julian Lonsdale, Zumtobel

The SFERA free-standing LED luminaire sets new standards in terms of empowerment in the workplace. This is made possible by combining sensControl with the new, innovative swarmControl technology. Several luminaires in an office automatically configure themselves into a swarm and communicate with each other in order to ensure the greatest possible lighting comfort.
Light that goes with you
New, innovative SWARMCONTROL technology uses a corridor function to ensure greater safety and orientation on the way to your workstation. A built-in presence detector in the luminaire activates the corridor function as soon as you enter the office. This luminaire then sends a radio signal to adjacent luminaires and these successively dim up to a corridor lighting level of approximately 200 lx (indirect light).
Light cloud for maximum lighting comfort
At the workstation, the SWARMCONTROL presence-based function ensures ideal lighting conditions with a mean illuminance level of up to 500 lx. Yet every staff member can adjust the lighting quantity at any time to suit his/her personal preferences. In addition, a radio signal to adjacent luminaires forms a light cloud. Depending on the amount of available daylight and artificial light, luminaires within
a specific radius are dimmed up to provide a pleasant room atmosphere.

Greater individuality and convenience

A study conducted by Zumtobel Research shows that more than 66 percent of users work in multi-person offices, where the task area often comprises two-person workstations. In order to meet these requirements, Zumtobel offers the SFERA free-standing luminaire with a high luminous flux that is typical of LED technology.

When combined with sensControl, the free-standing luminaire is even more intelligent, flexible and efficient. The presence detector automatically switches the luminaire on and switches it off again when the workstation is left unattended. The brightness sensor monitors the illuminance level across the desktop and dims the luminaire depending on the amount of light that is generally available.


Greater individuality and convenience

The SFERA free-standing LED luminaire delivers superb lighting quality while meeting the highest demands in terms of energy efficiency. It provides ideal lighting conditions in the workplace for a wide variety of visual tasks. It has a transparent, MPO+ based, light-directing optic and guarantees glare-free light for screen-based working. It provides maximum luminaire efficiency thanks to a large direct component. LEDs with a service life of up to 50,000 hours make this luminaire particularly sustainable.
