LED's have been around since 1962,they are just recently starting to be developed in high wattage form for general lighting and not just indicator lamps.
There is a difference between "discovered" and "invented". Sir Humprey Davy discovered the incandescent bulb in 1807 and Edison invented the practical bulb in 1879. So what do you think of the LED movement?
Update! This year the city of Watsonvile replaced most of the remaining HPS lights to LED for a total of 1800 units. They still have 400w HPS in the downtown area.
They recently replaced a few 100w HPS OV-15s in my neighbourhood with LEDs and the street is noticeably dimmer now. I hope it's a test install since only around 10 or so fixtures were replaced.
Can't used the : shock : smiley since i'm not at all surprised sadly.
