What Makes LED Lights Different?

LED Lights Bulbs in San Jose In a world where energy efficiency and eco-friendliness are becoming the standard, consumers are drawn to technologies that can make their lives better and can help them save money on their monthly energy bills. That’s why LEDs have become so popular in recent years. They can be used in any light fixture in San Jose, from chandeliers to kitchen lights. LEDs are bright, highly energy-efficient, and durable, having lifespans that far exceed those of their competitors.

What LED Lights Are

Light-emitting diodes, or LEDs, produce visible light when electricity is passed through a lead semiconductor. Unlike incandescent bulbs or CFLs that rely on heat energy as light sources, LEDs produce a minimal amount of heat, so they don’t burn out. Rather, their light quality and output, or lumens, diminishes over a long period of time.

How LED Lights Differ From Incandescent Lights

For many years, incandescent bulbs were the norm for home and outdoor lights. An incandescent light bulb produces visible light by using electricity to heat a wire filament. Once the metal reaches a high temperature, it glows hot and incandesces. This extremely hot filament is protected within a glass bulb that’s either filled with an inert gas or that’s devoid of air. In the case of halogen lights, tungsten filaments are used in combination with a halogen element, such as bromine or iodine, to produce a higher temperature, which allows for a brighter and purer light. Since incandescent lights produce so much heat—their energy output is 90% heat—they are not energy efficient, especially when compared with LEDs. That’s why they have been gradually replaced by other lighting sources like LEDs.

How LED Lights Differ From CFL Lights

Compact fluorescent lamps (CFL) were developed to be more energy-efficient and to replace incandescent lighting. Like a larger fluorescent tube light, a CFL bulb produces visible light by utilizing electrodes that allow electrical currents to pass between them while surrounded by gaseous mercury. These electrodes are placed at the ends of a long tube. As the electrical current passes between the electrodes, it excites the mercury vapor and produces an ultraviolet (UV) light. When the UV light interacts with the phosphor coating inside the bulb, visible light is produced. This entire process also generates heat—not as much as incandescent lights, but more than LEDs. Since CFLs contain mercury, they’re a bit tricky to dispose of.
