Difference Between LED Light and Fluorescent Light
Introduction to LED and Fluorescent Lighting
Lighting technology has evolved significantly over the past few decades, offering various options to suit different needs and preferences. Two of the most common types of lighting available today are LED (Light Emitting Diode) lights and fluorescent lights. Each type has its own unique characteristics, advantages, and applications. This article will delve into the key differences between LED and fluorescent lights, helping you make an informed choice for your lighting needs.
Understanding LED Lights
What is LED Lighting?
LED lighting refers to light fixtures that utilize light-emitting diodes to produce light. Unlike traditional incandescent bulbs, which use a filament that heats up to produce light, LEDs generate light through a process called electroluminescence. This process involves passing an electric current through a semiconductor material, causing it to emit light.
How LED Lights Work
LED lights work by applying a voltage to a diode, which is a semiconductor device. When the electrons in the diode move, they release energy in the form of photons, which we perceive as light. This process is highly efficient as it converts most of the energy into visible light with minimal heat production.
