Do you need a power supply for LED lights?
Whether you are building your own LED fixture, fixing and retrofitting existing fixtures, or purchasing new LED lights, you will need to find the correct power source for your LEDs. You will either need a constant current LED driver or a constant voltage power supply (or a combination of both) in order to make your LEDs work properly.
How do I choose a power supply for LED lighting?
You will either need a constant current LED driver or a constant voltage power supply (or a combination of both) in order to make your LEDs work properly. There are many different factors to consider when choosing a power supply for LED lighting. This post will go through those many factors and help you select the right power supply for your LEDs!
How to calculate led power supply needs?
Add a 20% buffer to your total wattage to ensure the power supply can handle the load without overheating. Verify that the power supply's output voltage matches the voltage required by your LED lights. This is a crucial aspect of how to calculate LED power supply needs accurately.
What is a LED power supply?
LED power supplies are often referred to as LED drivers, transformers, and PSUs. An LED power supply converts the higher AC voltage from your power source into the lower DC voltage required by your LEDs. For example, while most homes operate on 120V AC, your LED strip lights might need 12V or 24V DC to function.
How do I choose a power supply for COB LED lights?
