Summary

Led transformers regulate the current to the led circuits, the choice depends on the luminaire
Constant Current (CC) and Constant Voltage (CV) transformers differ in current and voltage control
Increase in temperature affects the power consumption and lifetime of the LED
Standard current transformers are best suited for individual LEDs or series connections
Constant voltage transformers are common for LED strips with built-in current limiter
