Why do I need to use LED protectors?
High-power LEDs offer long life, low power consumption, and low maintenance requirements, which makes them increasingly popular for outdoor applications.
But LEDs are sensitive electronic devices that can be damaged by overvoltage and overcurrent transients caused by system switching, electrostatic discharge and nearby lightning strikes.
In addition, the switch-mode power supplies used with LEDs do not provide the transient protection of the inductive ballasts they replace in lighting applications. This makes electrostatic discharge protection a must.
