Tailor made performance
Lighting designs using Garda can provide a large range of different illumination and uniformity levels to suit each
project. The combination of Garda’s symmetric and asymmetric distributions allows light to be directed exactly where it
is needed.
Garda uses the latest Luxeon TX LEDs set in specially designed modules to create truly asymmetric or symmetric
distributions. Made in multiples of 300mm lengths or flexible modules for curved rails, Garda offers a complete and
flexible lighting package to meet the British Standard (BS 5489-1:2013) or customer specified lighting levels.

Best practice used for designing the structural

Flexible installation
Mounting
Fixing can be via wall brackets, stanchions or onto existing structures with typical spacing’s every 1-1.5m. Bespoke
profiles can be designed and manufactured depending on the look and functionality required.
Loadings
We consider the following when designing the structural
elements of the scheme:
• Loading requirements
• Stanchion or bracket spacing
• Profile of the stanchion
The robust 3mm thick profile of the handrail is designed to
withstand loadings in excess of 3kN using bracket / stanchion
spacing’s of up to 2.1m. The combination of spacing and
stanchion profile is optimised to suit application loading
requirements and aesthetics. Some sample spacing’s (distance
achievable between LED module centres) are given below.

Where curved handrails require illumination, radii as small as 1.4m can be achieved.

Electrical considerations
Electrical installation of a Garda scheme is dependent on both the lighting requirements and the physical
characteristics of the scheme.
Electrical Layout
Total system power including the specification of transformers are calculated to suit each application. The following
issues are taken into consideration when we design our electrical solution:
•
•
•
•
Lighting performance
Total run length
Distance between transformer and first LED module
Cable size

wall bracket or stanchion

Power
Supply
Power enters the handrail via the brackets or stanchions at the end of the run. Ducting or conduit is typically required
between these points and the power enclosure. Multiple runs can be controlled by each transformer depending on
physical positioning. Each transformer can control the following quantities of modules.
