What Are the Different Types of LED Resistors?
There are many types of LED resistors, and they are categorized by the color of their light or the number of colors of light they produce. Many people think the color of the plastic housing on an LED resistor determines the type of LED light, but the color is actually a result of the wavelength of light emitted when a semiconductor metal is electrically excited. Most LEDs produce only one color of light, but some types offer two colors — bi-color — or three colors — tri-color — in a single LED package and can turn on one or more colors at the same time. Many types of LEDs are used in lighting situations that benefit from low power, long life, or bright light from very small bulbs.
