For the replacement of High Pressure Sodium Vapour The Luminaire utilises Power Light Emitting Diodes (LEDs) of high efficiency (100 lumens per watt), with a life duration of 50,000 hours (to 70% lumen maintenance) and 100,000 hours (to 50% lumen maintenance). It has more than seven times the visual efficiency of HPSV (which has a life of only 12,000-20,000 hours), and can withstand wide variation in input voltage. The light emitted has no infrared or ultraviolet radiation content
