LED lighting-disadvantage and advantage LED (Light Emitting Diode) technology, though over 50 years old, has recently gained popularity due to advancements in white LEDs, making it a sustainable and efficient lighting option. However, LEDs have some disadvantages, such as potential unreliability in extreme temperatures, sensitivity to heat, the need for costly heat management solutions, dependency on rare earth metals, and relatively high costs. Despite these challenges, LEDs offer significant advantages, including high energy efficiency (up to 135 lumens/watt), long lifespans (50,000 hours or more), ruggedness, instant lighting, effectiveness in cold temperatures, directional light control, excellent color rendering, and environmental friendliness, as they contain no hazardous substances.
