LED Resistors

We offer various types of LED resistors that are designed to be installed on our LED lights to reduce the voltage to the LED.

Why do you need a resistor with an LED? The LED resistors are designed to be installed on LED lights to reduce the voltage to the LED and to limit the current in the LED to a safe value. The important part about that for you is that a small change in voltage can produce a huge change in current. When you buy an LED, it should come with a rating that looks like this: 3.3V @ 20 mA typical. That gives you one point along the operating curve. Usually that’s a safe operating point. You may get a maximum rating in addition. It may be in the form of either a voltage or current. For example, a lot of people report buying “5V blue LEDs.” These are really not rated to operate continuously at 5V in most cases. We offer various types of resistors for different LED lights this gives you the liberty to choose from a huge number of choices and types.
