1, Compared to traditional LED heatsink,our's dissipating area is bigger,air convection is better,the temperature will be lower at least by 11 degree for PAR38.                     
2, Fin-shape design,there is no thermal silica inside the heatsink.                     
3, The weight of the cooling structure is lighter,only 50-60% of the traditional Cooler.                     
4, Good heat dissipation.                     
5, Very beautiful. The cooling structure is under patent protection.(Included the appearance.
