Anolis fixtures re-light Gerland Park in Lyon

Anolis ArcPar 150 Outdoor architectural luminaires have been installed for an urban lighting renovation scheme - halving the power consumption - in and around the Gerland Park district of Lyon, France. Gerland is a residential area that has also become a hub for emerging tech companies and commerce and a hotspot for sports and entertainment events with several venues located in its 7th arrondissement catchment area.

Lighting designer Laurent Fachard, founder of Les Éclairagistes Associés (LEA), has worked extensively in and around this area, and recently two of his key landscape lighting projects were updated with new LED technology that had subsequently come to the market. The new Anolis lighting replicates his original illuminated art, simultaneously making these urban lighting designs more energy efficient and sustainable.

The two areas that have been re-lit using the Anolis fixtures are the “Chromatic Garden” in Gerland Park, running adjacent to the river Rhône, and a landscaped roundabout on the Place des Docteurs Mérieux, part of the major road gateway into the city of Lyon. The job of completing this task fell to Thierry Marsick, head of the city of Lyon’s urban lighting department (DEU).

A main requirement for the new luminaires was to reproduce the original lighting scheme colours, including some - like yellow - which can be a challenge for LEDs. They also wanted to be able to focus the lights to obtain tight beams whilst maintaining maximum luminous flux.

DEU office project manager Frédéric Flacher and his assistant Jérôme Donna turned to the Anolis ArcPar 150 fixtures. The decision came following several options initially considered and testing into exactly how to re-light both areas. The ArcPar 150’s RGBA colour mix provides up to 1,676 lumens with 7 x 40 W multichip LEDs achieving a total of 220 W of power consumption compared to 430 W drawn by the previous metal halide lighting - representing an energy saving of 51% for this architectural lighting.

Anolis modified the units to remove the screen and buttons at the back, and DEU wanted a specific version of the management software allowing the user to choose the focal length and colour/hue of the projector remotely which facilitates both lighting adjustments and ongoing maintenance. The same customised software also switches the Anolis units on and off at the requisite times.

Chromatic Garden, Gerland Park

Gerland Park was inaugurated in 2000 by landscape designer Michel Corajoud. The contemporary concept is organised around a 650 m by 40 m area comprising different rectilinear strips, each with an array of varied horticultural elements, plants, and foliage. Close to the confluence of the Rhône and Saône rivers, it is a 22-hectare area on the outskirts of Lyon.

Laurent Fachard’s architectural and landscape lighting for the park transforms it into a “chromatic garden” at night. Seven colours of light are used: mauve, red, orange, yellow, green, blue, and violet. Coloured shadows and textures shift and change in harmony with the plants and the transitioning seasons.

In the new lighting scheme, eighty Anolis ArcPar 150 Outdoor spotlights are installed which were supplied by Saint-Genis-Laval based Anolis distributor Tech’Lux, in collaboration with installer Spie which is also in Lyon.

Landscaped roundabout on the Place des Docteurs Mérieux

This southern gateway to Lyon offers the main access to the city via the ring road and the Autoroute du Soleil. From the Musée des Confluences via the Pasteur Bridge, drivers arrive at a four-lane landscaped roundabout, with an outer ring for bicycles. Visible at 360°, the central median of the roundabout takes the form of an arena. Plane trees stand in the middle, and the space is planted with multiple shrubs and herbaceous plants.

The roundabout is adjacent to the Place des Docteurs Charles et Christophe Mérieux, which overlooks the Tony Garnier Hall, one of Gerland’s major venues. The whole area was laid out by Michel Corajoud in 2008. To highlight this site, LEA proposed creating an “impressionist painting” visible at 360° with blue functional lighting detailing the roundabout ring, a picture now achieved using twenty-two Anolis ArcPar 150 Outdoor floodlights.

The central reservation features rich coloured landscape lighting. Two high “needle masts” are installed at the rotation axes of the “arena”; they once housed a cluster of circular discharge floodlights with dichroic glass filters and different optics and now host the Anolis ArcPar 150s.

Getting the new Anolis lights to mimic the look and style of the original lighting installation took the DEU team two nights of programming and adjustment. The roundabout’s coloured illumination is currently taking place only on Saturday evenings, a political choice to align with the city of Lyon’s overall energy conservation plan.
