Entry DescriptionThe Euclid 40 WE ERLE System has a working life of up to 30 years due to its unique design, which allows for the Easily Replaceable Light Engines (ERLE) to be replaced without using specialist tools or requiring the system to be removed from its mounting location.
The system is designed for use in interior applications where dynamic cove lighting is required.
A clamshell design clamps the aluminium core light engines to the heat sink with a cam action, ensuring excellent thermal management.
Once the side panel is released by the locks and hinged open, the light engines can be easily accessed and unplugged from the wiring loom. New light engines can then be connected, pushed into position, and the hinged panel closed and locked.
The system produces decorative, dynamic effects using a combination of various CCT and colour LEDs, DMX controlled dimming sequences, and textured glass optics. Lit effects can be customised by adjusting these elements.
Being able change the textured glass and the LED board allows for easy on-site customisation.
Remote DMX drivers can be replaced at their end of life. The dimming sequences can be modified on-site.
Custom length modules can be specified and the system can be configured for straight runs or as an articulated system for curved locations.
The output is up to 4,000 lumens per mtr, depending on the mix of LEDs and the textured glass.
Sustainability ApproachWe aim for our systems to have a working life of up to 30 years.
Traditional construction methods allow this system to be easily disassembled. 95% of the components can be reused indefinitely.
Easy on-site replacement of light engines is a key element of the design of all new Radiant systems, and the Euclid 40 WE ERLE System IP20 is one of the first examples of this approach.
Keeping the lighting system in use for an extended period of time is one of the most effective ways to reduce the overall carbon footprint of this type of system.
Plastic parts can be specified in PA11 bio-based resin, and the extrusions can be produced in post-consumer waste aluminium.
The aluminium core PCBs can be recycled at the end of their life.
All Radiant systems come with a 5-year guarantee, with a refurbishment service thereafter.
A project-specific TM66 analysis can be prepared for this system.
