Heat Dissipation: Each size of heat sink is well designed. It exists micro-slit made with one-step molding technology through which the heat can be easily taken away by airflow.
Optical Design: The innovative design was accomplished jointly by American, China Taiwanese and Mainland experts after a year of hard work. It showed the excellent quadratic light distribution and illuminance.
System Luminous Efficacy: Luminaire luminous efficacy reached more than *0%.
Selected quality chips: The chips we used are supplied by the renowned companies in order to ensure the quality of our products. Such as Cree , Epistar, etc.

Non-imaging second optics design: project light more efficiently by iso-luminance energy distribution
Optical module after second array optical: improving efficiency by omitting front cover
Keeping light uniformity even individual LEDs crush out
Junction temperature of module not more than *0℃ due to low RTH construction design excellence heat dissipation design
Multipath constant floe source driver circuit promising working stability
PWM intelligent dimmer and time-share control saving more energy
Light efficiency more than **0Lm/W , CRI more than *0   ( for street light)
I0~*5 : Imax≈1:3.4,  higher luminance uniformity and low LPD index
