ENERTEK Intelligent Power Saving Streetlight

4 Advanced Techniques
•Reflector of accurate positioning and multiple facets mirror surface
•Intelligent electronic ballast
•Automatic compensation of light decline
•Automatic dimmer

ENERTEK Intelligent Power Saving Streetlight Features:
Structural design: simple and scientific, excellent glare control

Aluminum case: made by die-casting technology, high intensity, corrosion resistant and durable, temperature under 65℃

Light filter cover: made of tempered glass, high light preciousness, solid

Sealing ring: made of new-type silica gel, high temperature resistance, anti-aging, reflection cavity with IP66 protection

Reflector: with up to 265 facets mirror surface and accurate positioning function, efficient distribution of most light ray by one single reflection. The reflection rate is up to 94%.

Electrical apparatus: intelligent electronic ballast, automatic midnight power control, no worry about theft and heat emission 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.


Intelligent electronic ballast
Intelligent electronic ballast used in ENERTEK Streetlight adopts latest technology, efficient and stable. It perfectly realizes the functions of constant luminance output, intelligent street light controller, automatic compensation of light decline and automatic dimmer at midnight, and ultra low self loss in addition, achieving excellent energy saving performance.

Substitution solution by ENERTEK
With a combination of innovative technologies, ENERTEK Streetlight utilizes electrical energy to the maximum extent possible, using its 150W to substitute 250W common streetlight and 250W to substitute 400W.
