The ND HB A 93 is an affordable, highly reliable and ultra energy efficient lighting system for outdoor advertising. While illuminating an area of two square meters with 350 Lux, the ND HB A 93 consumes only 9 Watts of power and lasts for 100,000 hours. Light sources currently used in conventional advertising lighting systems last only for about 10,000 hours and consume eight times more power than the ND HB A 93. In the light of rising energy costs, the ND HB A 93 is an intelligent replacement for conventional outdoor advertising lighting.
