The heat dissipation problem: Small straight flashlight circuit carefully configured in order to ensure that the LED heat can smoothly pass through the circuit warehouse and light cup Flashlight, fine workmanship can only guarantee a good thermal conductivity. However, flashlight shape is restricted, the external heat cannot be the bulk of flashlight, hope everyone can understand. Heat by the flashlight is a normal phenomenon. When the temperature gets too high, allow the flashlight to be off for some time before re-use, do not allow it to run for a long time in the open tube lights to prevent accidents.

On light concentrating problem: For the same LED, but with different reflector can had different impact of light surface. The bigger the reflector, the bigger the light surface.
