The Basics of LED Drivers from Lighting Supply

*Video Update: Constant Voltage fixtures are rated in volts.
Today we're going to talk about LED drivers.
The two main types of LED drivers are "constant current" and "constant voltage."
From its name, you'll see that a constant current driver provides a constant current output while the output voltage is variable. Constant current LED drivers are the most popular. Applications include lamps and outdoor fixtures -- anything that's singular and you already know what the electrical characteristics are going to be.
With a constant voltage LED driver, the output voltage stays the same but the output current or amperage is variable. Applications include outdoor LED signage and linear architectural applications. Many times you won't know how many fixtures you'll be using, and this is where a constant voltage driver can help.
You can tell which LED driver to use from the LED light source. Typically a manufacturer will list constant current or constant voltage on the light source. If you do not see that, you can look for the rating. A constant voltage fixture will be rated in volts, or V; a constant current fixture will be rated in milliamps, or mA.
As always, if you're confused about what to buy and need a hand with your purchase, don't hesitate to give Lighting Supply at call at 877-231-2852.
