Constant Current LED Drivers
Constant current drivers are designed for LED lights that require a fixed output current and a ranged output voltages. This type of driver will have one specified output current labeled in amps and a range of voltages that will vary depending on the wattage rating of the LED. Using a higher amp rate will make the LED brighter; however, it will eventually over-drive the LED which results in reduced life-span and premature failure. Since constant current drivers maintain a consistent brightness, they are often used for signs, back-lighting, and commercial LED displays.
