These festive illuminations utilize light-emitting diodes (LEDs) to produce a variety of hues. Typically, these lights incorporate a small microchip that controls the flow of current to the different colored LEDs within a single bulb, allowing for a range of pre-programmed or user-customized displays.
Their popularity stems from several advantages. LEDs offer significant energy savings compared to traditional incandescent bulbs, resulting in lower electricity bills. They also generate less heat, reducing the risk of fire hazards. Furthermore, their durability and long lifespan contribute to a reduced need for replacements, promoting sustainability. This technology’s evolution represents a significant advancement from the simple, single-color incandescent Christmas lights of the past, opening up a world of dynamic and customizable decorative possibilities.
