How do LED light drivers work?
An LED driver is an electrical device that regulates power to an LED or a string of LEDs. Forward Voltage is the amount of volts the light emitting diode requires to conduct electricity and light up. As temperature increases, the forward voltage of the LED decreases, causing the LED to draw more current.
How to select LED drivers?
Use an LED driver with at least the same value as your LED(s). The driver must have a higher output power than your LEDs require for extra safety. If the output is equivalent to the LED power requirements, it is running at full power. Running at full power may cause the driver to have a shorter life span.
How does constant current LED driver work?
A constant current LED driver varies the voltage across the electronic circuit in order to maintain a constant electrical current. This guarantees that no matter the fluctuation in voltage, the current driven to the LED will be maintained at the specified level.
Why use an LED driver?
An LED driver’s main purpose is to rectify higher voltage, alternating current to low voltage, direct current. LED drivers also protect LEDs from voltage or current fluctuations. Too much or too little current can therefore cause light output to vary or degrade faster due to higher temperatures within the LED.

How long does LED driver last?
Namely, the life of the driving circuit expires prior to when the LED stops emitting light or has its brightness dropped. The typical nominal lifetime of these elements is often times less than 25,000 hours, while the lifetime of LED itself could be as long as 50,000-100,000 hours.
