Siella LED

the standard in office lighting

The challenge

Recessed LED luminaires are standard for office lighting. In addition to costs and quality, the focus is increasingly on flexibility. Solutions are needed that can be flexibly adapted to the various applications in terms of appearance, construction design and method of installation.

The solution

The next generation is here: the Siella LED range has been an attractive entry product into the world of modern office lighting for many years, scoring points as an ideal total package. Siella LED is available either as a square recessed or rectangular surface-mounted solution with two different optics – and with its simple design and pleasant light it blends harmoniously into any office environment. The material quality and quality of light have been further improved and installation and operational benefits have been optimised.

Advantages with lighting design

High cost-efficiency

Low investment costs and high energy efficiency of up to 121 lm/W make Siella LED an economically attractive solution that pays for itself within a very short time. Compared to the previous generation, Siella LED now provides even more efficiency with 4,000 lm.

 

A flat design for high flexibility

Siella LED has an external electronic control gear unit. This makes the luminaire flat enough to fit into nearly any intermediate ceiling space.

Light for any office environment

Siella LED is available with two different optics, so that even different office environments can be illuminated using a uniform design vocabulary. With UGR19 glare control, the luminaire is suitable for the standard-compliant lighting of computer workstations. The UGR22 version is recommended for all other areas.

Accessories for a wide range of applications

Siella LED can also be used as a surface-mounted luminaire with an optionally available mounting frame. Siella M84 with accessories is also available for plasterboard ceilings upon request.

Advantages during installation

Light-weight

Compared to the previous version, the luminaire’s weight has nearly halved. Thanks to a high-quality aluminium frame, the luminaire still maintains its stability. This combination facilitates handling and ensures effortless, time-saving installation.

Simple, quick installation

The external electronic control gear unit of Siella LED allows for especially simple installation and replacement. It can be mounted separately from the luminaires and connected to the luminaire via plug & play. A supplementary connection box is not required.

Advantages in operation

A simple design and good quality of light

Siella LED is installed flush with the ceiling and blends harmoniously into any office environment thanks to its simple design. Its quality of light remains just as high as before, pleasantly homogeneous and without any visible LED points.

Simple control

The DALI devices are equipped as standard with an optimised touch dim function for simple light control in everyday office use. This touch-dim function has been fundamentally revised and significantly improved: with Siella LED, a total cable length of up to 25 metres (push-button to the last luminaire) and the use of 10 luminaires is possible.

Attractive entry solution

Low investment costs and high energy efficiency make the Siella LED the perfect solution in the entry-level segment.

Improved quality

The material quality, quality of light and advantages in operation have been further optimised in the latest generation.

Harmonious overall appearance

Due to the flush ceiling connection and uniformly illuminated light emission surface, the luminaire blends well into any office surroundings.

Two optics

Siella LED is optionally available with UGR19 for computer workstations or with UGR22 for all other areas.
