How has the light emitting diode impacted society today?

Because of the light emitting diode, society has found a far better way for a safer, high quality and energy efficient method of lighting compared to what we used in the past.

Here is the reasons:

- Light derived from candles tend to have higher probability to cause a fire in the house, which make them a really dangerous method for lightning.

- LED only use around 8 watts for every Watts that halogen light bulbs use, so it's very energy efficient,

- LED typically last linger than halogen bulbs (around 20-25 times longer)
