Lumileds Lighting is now shipping a warm white version of its high-brightness Luxeon LEDs, becoming the first manufacturer to deliver a warm white emitter in production quantities.
These were perceived by the public as dark and unwelcoming, underlining the need for a single centre that created a welcoming environment for both the local community and the Service Centre staff.
To achieve this Stevenage Borough Council appointed Future Group Lighting Design and Light Projects, a certified member of the Luxeon Lighting Network, to help create a new light and friendly internal environment through the creative use of light.
The first project of its kind in the UK, the architect Brian Martin designed a feature ceiling, consisting of a series of coffered arcs that conceal a light solution specially developed by the Future Group using 2,500 Light Projects KlipLEDs.

Unique Lighting on Luxury Yacht
Lumileds' Luxeon light sources have been used by lighting manufacturer LightGraphix, in a project to light the luxury £14 million, 140 foot sailing yacht Gimlä.
Comprising Luxeon I LEDs, the KlipLEDs were individually mounted on metal strips and press studded together to form a flexible mechanical coupling, capable of running in a channel around the curved ceiling arcs.
Both white and blue Luxeon I LEDs were used to create a colour changing effect that runs over the course of the day, simulating the sky and creating a feeling of light and space.
The aspect ratio of the coffers in the ceiling design was vital to the overall effect of the project, with the correct ratio only possible through the small size of the Luxeon LEDs.
The small size and high brightness of Luxeon ensured the lip detail needed to conceal them was kept to a minimum, allowing the architect to achieve the desired effect.
Without the use of Luxeon LEDs in this project the arc design and final effect would not have been possible.
Only a year or so ago cold cathode would have been used resulting in a larger lip detail and altering the aspect ratio.
Crucial to the success of the project is the fact that there are no LED drivers, tungsten halogen transformers or any serviceable components above the feature ceiling, avoiding the need for any trap doors that would impact on the overall design.
The drivers are all housed in a 19-inch rack in a plant room, with the ELV cabling from there to the LEDs cut to length so there are no joints.
The cables are each terminated with a tiny socket passing through specially positioned holes concealed behind the lip detail.
This enables each driver to run three circuits each with between four and twelve LEDs in a balanced load.
The long life of Luxeon LEDs also ensures that maintenance of the lighting solution is kept to a minimum.
In terms of energy savings, Luxeon LEDs have very low power requirements, resulting in low operating costs and on-going energy savings for the council.
The Customer Service Centre now provides a one-stop shop for the people of Stevenage to discuss council issues either face to face with advisors, or by telephone with the main call centre.
Both services are housed within the new Customer Service Centre building, with a glass wall separating the two departments and the simulated sky enhancing the environment of both sections.
The lighting solution has proved very popular with both the Service Centre staff and the members of the public visiting the centre, with very positive feedback on the overall lighting design and the welcoming atmosphere it now creates.
