What are the disadvantages of LED lights?
What are the disadvantages of LEDs? High up-front costs. Transformer compatibility. Potential color shift over lamp life. Performance standardization has not yet been streamlined. Overheating can cause reduced lamp life.
Why incandescent bulbs are better?
Incandescent bulbs look so good because they emit all colors of light, whereas LEDs and other more efficient light sources only manage a subset of all the colors of visible light. This “full-spectrum” light also means incandescents are better than anything else at rendering colored objects faithfully.
