LEDs (H.W.) Chelsea

LEDs are semiconductor diodes, electronic devices that permit current to flow in only one direction.

One of the biggest differences between LEDs and halogen light bulbs is their lifespan. LEDs can last up to 80,000 hours. Halogen light bulbs only last between 2,000 and 6,000 hours.

In all country's we use the LEDs but in the das of Ney York City are a lot of them.
