problem
ENERTEK Intelligent Power
Saving Streetlight:A New Energy-saving Technology for Road
Lighting
ENERTEK Reflector
ENERTEK intelligent street light system adopts innovative
technology. Its reflector of accurate positioning and multiple
facets mirror surface can remarkably raise the luminous efficacy.
ENERTEK Streetlight of automatic street light control has
much better performance than common streetlight in the
utilization of light ray, comprehensive luminous efficacy, ands
power density.
