Solar Bollard Gen 2 is an Effective PP5 Compliant Light with Little Light Waste
At Gillean Place in Lara, five 1m high, 120mA Solar Bollards spaced ~8m apart met AS/NZS Pedestrian Compliance lighting (PP5). While the feature photo isn’t going to win any photography awards, you can see there is no “back-light” thrown from the Solar Bollards. All light is thrown onto the path rather than backward up onto the fence (and wasted).
PP5, in practice, means there is no “dark spots” between the light on the path between each bollard – the light splay “joins up”.
The physical features of the SBL2 that make it “efficient” is the asymmetric LED arrangement, the superior optic used, and the placement of the LEDs along the “ceiling” of the inner cone that direct all light “onto the path”.
