Here are a few examples:
Maybe it occurs to some to ask how much energy it takes to produce such a sun tunnel, and if that energy and its waste products are compensated by its savings during its lifetime. Some types of sun tunnels are produced from materials whose lifetime is only a few years and yet their production requires the same amount of energy as Lightway. From the environmental viewpoint, it is questionable whether to install such imperfect sun tunnels at all. Their lower performance and short lifetime aren’t able to erase the carbon footprint which their production has set on our earth. Lightway annually produces, sells and installs thousands of sets of sun tunnels to satisfied users who often don’t even realize the greater implications of their decision to buy Lightway and what this decision is doing for the Earth. We therefore thank them for doing so and not only helping themselves, but helping all of us on the Earth to breathe better air and continue to have a beautiful environment.
