Flexbeam
Suspended narrow profile luminaires with acoustic attenuation
OVERVIEW
The Flexbeam is a suspended acoustic luminaire with low glare optics. Installation alongside non-luminaire acoustic baffles creates a coherent aesthetic across the ceiling. Available in 3 standard colours and reflector options to suit the space. Other colours are available on request.
Applications: Teaching spaces, Offices, Meeting rooms, Breakout areas, Reception areas and Circulation spaces

Suspended narrow profile linear luminaires with acoustic attenuation
Introducing Flexbeam
Flexbeam combines high performance low glare lighting with a luminaire body that provides acoustic attenuation designed to absorb unwanted reverberation and echo. Ideal for environments where audio clarity and efficient, well-controlled lighting is required.
Flexbeam incorporates nanoprism optical control with a range of glare reducing reflectors, allowing luminaire brightness to match the needs of the user for optimum comfort. By combining two important functions, Flexbeam can create minimalist designs for a variety of applications.
Versions of Flexbeam without integrated lighting are also available which can be tailored to the specific needs of your project.
Add a splash of colour
Flexbeam is available in marble white, charcoal grey and black finishes as standard, however a wide variety of other colours are available to special order. Make your project stand out with a bold and vibrant Flexbeam colour.

Flexbeam is made from over 47 recycled plastic bottles
Performance, but not at the cost of the environment
The Flexbeam sound absorbing body is manufactured from 65% recycled PET (polyethylene terephthalate) with over 47 recycled plastic bottles used in every baffle. Not only that, it is 100% recyclable at the end of life. The high quality components give Flexbeam a rated life of 100,000 hours L80/B10 ensuring a long and reliable lifetime, reducing the need for replacements and/or maintenance.
Acoustic absorption performance
The acoustic performance of Flexbeam has been independently tested at the University of Salford, Manchester. Acoustic performance is measured as the rate of reverberation decay over a specific period; the faster sound decays, the lower the reverberation time and the better the acoustic properties of the space.
The Flexbeam body is manufactured from sound absorbing material, designed to increase voice and audio clarity by reducing unwanted reverberations and echo.
Flexbeam has been acoustically tested in accordance with BS EN ISO 354 for its equivalent sound absorption coefficient.
More detailed acoustic data for the Flexbeam is available upon request from our Technical Department.
Sound Absorption Coefficient (α)
Data based on a spacing of 450mm
Sound solution
The Flexbeam is designed to create an acoustic ceiling. Our experts can combine the acoustic and lighting design to create a complete coherent solution for your specific requirements.
Luminaire layouts can limit the available locations for acoustic ceiling material and vice-versa. By combining the two functions together, a Flexbeam solution can be used to declutter the ceiling and reduce the overall cost of the installation.
Application Examples
Office
This office space has a floor area of 48 m² and has been treated with 8 Flexbeam luminaires resulting in a reverberation time of 1.17 Tmf. No additional acoustic material is required. The Flexbeam luminaire provides all the acoustic attenuation. This results in a clearer ceiling.
Target RT – 1.2 Tmf (BB93 for refurb buildings*)
Result RT – 1.17 Tmf
Secondary School Classroom
This secondary school classroom has a floor area of 60 m² and has been treated with 9 Flexbeam luminaires and 12 plain Flexbeam baffles resulting in a reverberation time of 0.99 Tmf.
Target RT – 1 Tmf (BB93 for refurb buildings*)
Result RT – 0.99 Tmf
Large Meeting Room
Meeting rooms can vary in size and shape and can often require a creative lighting solution. This large meeting room has a floor area of 28 m² and has been treated with 4 Flexbeam luminaires and 11 plain Flexbeam baffles resulting in a reverberation time of 0.80 Tmf.
Target RT – 0.80 Tmf (BB93 for refurb buildings*)
Result RT – 0.80 Tmf
Furniture not included. Reverberation time will decrease further with furniture.
