In order to know about whether the WP02RGB is rain proof or not,we use a big shower head to creat rainy environment.
We first power on the laser,then let the water drop down fast from the shower head to the laser housing.
The tested laser will be showered for 72 hours in this container,every 8 hours power on then 8 hours power off.
After 72 hours experiment,the laser still working on well and there is no water into the housing.
So it is suitable for the outdoor events,no need to worry about the rainy and snowy day.
