The Light Lab manufactured and installed this stunning bespoke atrium light feature at the commercial offices of Broadgate Quarter in the City. The installation took place over a 6 week period, using our specialist installers, working alongside a team of abseilers, to ensure that each bespoke halo structure was installed as designed. This is our largest atrium lighting project to date, with the installation reaching almost the full length of the 50 metre atrium.
Working to the detailed concept design of lighting designers Cundall & John Robertson Architects, we initially produced a full scale mock up (as we often do for large scale projects), comprising of one complete illuminated ring that we winched to the top of the atrium for the design team review.
When tackling the full project, the main design challenges involved the structure of the feature; particularly the balance of providing sufficient strength to each illuminated ring, whilst ensuring there was no visible shadowing. At the same time there was the requirement of a very light-weight structure to fix to the existing atrium support beams. The final design was approximately 750Kg per chandelier (including all cabling) which for a 45m long structure, was a considerable design challenge. The cabling alone was a sizeable task, requiring the running and managing of over 1km of cabling of sufficient size, to ensure all LED rings were consistently and evenly illuminated.

Project Manager Graeme Laurie on the installation challenges of this project: “When it came to the actual installation, the biggest challenge was how to install such a large piece within the confines of a (relatively) restricted area. With minimal access to the atrium area and a restrictive weight allowance, installation using even the smallest cranes wasn’t an option. Similarly, the access issue prevented us building the individual rings off site; we therefore set up shop in the atrium and the rings were assembled in situ. We then built the structures from the ground up, winching them gradually into place (via a lifting frame and manual winches), with the feature effectively growing from the atrium floor and slowly filling the space”
Andrew Bissell from Cundall, speaks of the close working relationship between the designers and The Light Lab, to ensure the installation ran smoothly and was completely true to the design.
“Having designed such a large lighting element to fill the atrium space, we needed to be sure the design intent was retained through the construction detail and installation process. The Light Lab understand the importance of even the smallest of details and how to manage and undertake an installation of this nature. As such the client has the lighting effect originally presented along with a high quality and low maintenance product and installation”.
