The lakeside promenade connects the pier to the historic center of Varenna. Respect for the landscape value of the walkway led to the choice of newly developed LED technology devices with high performance and a very limited visual impact. This ensures good luminous efficiency, minimum bulk, high-level impact protection, very low installed power, and reduced maintenance costs. The devices used are “Glimcube”, produced by iGuzzini, specially designed to evenly illuminate walkway areas. Positioned on the railing pillars and separated by a minimum distance of 4.2 m at a height of 10 cm from the ground, they light up the walking surface and, by means of reflection, also ensure suitable illuminance values on the vertical planes. The distribution of light intensities within an angle of 180° rules out any risk of glare when viewing the lake landscape. 67 devices were installed in total. The power supply units were grouped separately from the devices, taking advantage of the recesses left vacant by the old lighting system, and protected by sealing components.
