Aluminum has excellent heat dissipation ability, which can prevent the bulb from burning out due to high temperature. PS: it is normal for the head of the lamp to generate heat, because only about 30% of the electric energy of the LED light source is converted into light energy, and the rest of the energy is converted into heat energy. Therefore, we use aluminum materials with excellent heat dissipation capacity instead of plastic materials. This will prevent the bulb from burning out.
