Better air convection; and the radiator is extruded, the density is low; these two  characters could make a better heart outputting.
The Design of Metal Bolt with LED source, which could enhance the rate of thermal conduction.
There are optical lens above LED, and another lens outside the LED Source, these lens could change the spot lamp-house to rectangle surface lamp-house.
The driving circuit could change AC to DC and then constant-current.
Uniformity of luminance >0.6%.
We have done the test that our light could work above 9 total days underwater that is **6 hours.
We could make the guarantee that the duration of our light is above *0,**0 hours.
