Twilight Bilbao.
Good light only.
Light should go only where needed.
Twilight Bilbao eliminates optical pollution, cancelling
useless light, meaning intrusive light that penetrates our
houses or light that is dispersed upwards, outshining the
stars. A compact truncated conical screen only generates
a downward emission, complying with the strictest
standards of lighting pollution and favouring energy saving.
Visual comfort* is excellent with G6 (intensity is null
at 90°) and D6 values, eliminating all physiological
and psychological glare. It also eliminates the disturbing
intrusive light, which is a real source of pollution and
a cause of sleep disorders. Twilight Bilbao is focused
on good, useful and efficient light.
* In urban (not street) lighting disability glare is measured with parameter G and discomfort glare with indicator D.
