Thanks to the trust and cooperation with Jaco, s.r.o. we had the opportunity to collaborate on an interesting project to illuminate the Memorial to members of the 1st Czechoslovak Army Corps. With respect and a considerable dose of humility before the significance of this monument, we set out to make custom-made LED spotlights. When designing LED spotlights, we also had to take into account the requirements of conservationists and nature conservation. Our experiences with the production of custom-made LED spotlights was very useful. Thanks to them, we have minimized the creation of unnecessary and harmful light smog. We believe that even with our small contribution with the lighting of this monument, we will pay tribute to the fallen and bring closer the sad history of this place, so that it will be a warning and an instruction for us contemporaries.
