The data for an S2 project clearly shows that for the same
illuminance (10 lux, average required) one Plurio lantern can replace
two opal globe lanterns. For a new lighting project, for instance a
pedestrian open zone as described on the former page, wider spacings
between the Plurio lanterns brings the benefits of enhanced accessibility
and less clutter in the public spaces, whilst retaining uniformity and
illumination levels. The resulting savings are shown below:
