Rome is undergoing a city-wide plan to change its public illumination from the current yellow sodium street lights CK to white LED lamps. In making the change, Rome joins a long line of cities around the world that have switched to the cheaper, and more environmentally friendly LED lighting, and it is not the first city where that change has come at the price of protest.<br />
<br />
Since July, some 100,000 led lights have already been installed, just over half the number that will be substituted in the 53 million euro changeover that is expected to save the city millions of euros in electrical bills. But when Rome’s municipal electrical utility ACEA began to substitute the lamps in Rome’s historic center, residents began to take note.
