Lighting Assessment WAI-985-000-REPLC-0019_Rev 0.Docx Waihi North Project Page 15 of 35 21/06/2022 Assessment of Environmental Effects: Lighting REVISION: 0 - Final Figure 6: Typical Mobile Lighting Plant o Mobile plant location and orientation will vary over time in response to construction activities and locations. • Vehicle mounted rotating or flashing amber security beacons. o All vehicles operating on site would be required to have roof mounted security beacons unless parked in designated areas. • Standard vehicle head and tail lights. o Required to be used in low light conditions and possibly during some construction activities and at some locations. • Permanent exterior lighting – pole and building mounted o Exterior luminaires would use 3000K, or warmer, LEDs wherever practicable to minimise the lighting wavelengths at the cooler end of the spectrum. LEDs at the warmer end of the spectrum (3000K) are more friendly to night sky observers and fauna than those at the cooler end of the spectrum (4000K). o Permanent lighting would consist of LED luminaires designed and installed with minimal upward light output configuration to minimise direct upward light spill. Where luminaires are required to be tilted, they would be aimed away from primary external viewing locations to minimise direct glare effects. o A small amount of security lighting would be provided to the vehicle parking areas, the water ponds, and pedestrian pathways.
