2. Shell: The other part of LED projection lamp is the shell, because the heat of the LED needs the heat dissipation of the shell, so the shell material is good, and then most of the LED projection lamp need to be waterproof, IP grade to more than 65, in order to ensure the quality of outdoor use, so the shell waterproof is also very important, overall is that the shell material is good, abrasives to match, there can not be leakage.

3. Driving power supply: This is the heart of LED high-power projection lamp. If the driving power supply is not good, it is like a person with heart disease and danger at any time. Therefore, the driving power supply is also required to be very high, not to say high technology, but to design the power supply according to the normal situation. If there is a shortcut through the power supply, the power supply is unreasonable and easy to break down.

4. Production process: This is the last step to check the quality when the first three conditions are satisfied. No matter how good the material is, no fine production process can produce good quality products. So the process is very important. This check is very simple. It depends on the appearance of the LED spotlight. The appearance of the process is sure to be good, and there will be no hanging flowers, and others.

Waterproof glue residue and so on.
