The visible light there is from the UV emitter now looks cyan, while the IR beam that normally isn't visible at all looks the way the UV emitter's visible beam does to the naked eye.

An elected leader is chosen by a vote of the public, while an appointed leader is selected by another leader or a body of officials without the public directly participating. Both types of leaders have been important in American history, particularly in how they exercise their authority.
The United States is a federation, with elected officials at the federal (national), state and local levels. On a national level, the head of state, the President, is elected indirectly by the people, through an Electoral College. Today, the electors virtually always vote with the popular vote of their state. All members of the federal legislature, the Congress, are directly elected. There are many elected offices at state level, each state having at least an elective Governor and legislature. There are also elected offices at the local level, in counties and cities. According to political science professor Jennifer Lawless, there were 519,682 elected officials in the United States as of 2012.
