To figure out what size LED driver will meet your needs, you need to know the following:
The power supply voltage you will be using
The total power used by the system LEDs
What voltage or constant current the LEDs require
If any other technical factors exist, such as the need for precise color control or the possibility of water contact, they will affect how the LED driver works. The IP rating of an LED indicates its water resistance; a higher rating means it is more resistant. This product has an IP rating of 44, which is suitable for use in the kitchen and other places where water may occasionally splash. Drivers with higher IP ratings (such as 67) can be used outdoors. Drivers with an IP rating of 20 can only be used indoors in a dry environment.
