In need of cost effective pathway lighting, the National Arboretum in Canberra approached BlackFrog Solar for a possible solar solution. The bollards had to be high quality, over one metre tall and be of heavy duty construction suitable for a public space. Other requirements included all night lighting, sufficient brightness to satisfy Australian pathway lighting standards and the ability for some bollards to be removable to enable occasional vehicle access. The Delta solar bollard was the ideal solution. As it was for pathway lighting only, BlackFrog Solar suggested the PIR (proximity infra red) option to ensure all night lighting even with several days of overcast weather. The reduced standby light level was also better suited to minimize light affecting neighbouring areas, whilst the full brightness level when triggered, was ideal for pathway users.
As a result, the National Arboretum have installed 85 of the Delta solar bollards with PIR sensor, including 15 removable bollards.
