Way back in 1976 the Empire State Building began changing colors at night, to honor events or organizations.
This was a bonanza for NYC electricians.
Hours of labor was required each time to remove hundreds of florescent tube lights and swap-out their plastic sleeves.
That all changed in 2012 when ownership installed a new computer controlled LED lighting system.
Now 16 million colors are on tap at the flip of a dial, instantaneously, and on six different building levels.
The Empire State Re-Building program,
an energy efficient retrofit of the entire building,
has exceeded expectations.
It has saved almost $8 million dollars in electrical costs in just the first three years of operation.

To say nothing of all that union labor.
