FIRST…Make Sure you have control of the current to your LEDs

Most LEDs need a current-limiting device (whether that be a driver or resistors) in order to prevent LEDs from being over driven. This constant current driver or current limiting resistor is used to regulate current to the LEDs, keeping them running safe and maximizing their lifetime. LEDs electrical characteristics change as they heat up; if current is not regulated, LEDs will draw too much current over time. This overdraw of current will make LED brightness fluctuate, leading to high internal heat that will eventually lead to failure of the LED light. If you are building your own LED fixture or working with any of our component star LEDs, you will need a constant current device within your system. Most finished LED products or LED strip lights (that you would buy straight from the store) already have drivers or resistors built in to regulate the current. If you are unsure whether you need a constant current source, take a look at this helpful post in order to find out. If you don’t have a current limiting device, finding a driver is your first step; but if your LED product already has current under control, you can follow this post in finding a constant voltage power supply.
