The fifteenth century also sees the first evidence of ceremonial regalia.

Recent developments in LEDs permit them to be used in environmental and task lighting. LEDs have many advantages over incandescent light sources including lower energy consumption, longer lifetime, improved physical robustness, smaller size, and faster switching. Light-emitting diodes are now used in applications as diverse as aviation lighting, automotive headlamps, advertising, general lighting, traffic signals, camera flashes and lighted wallpaper. As of 2015[update], LEDs powerful enough for room lighting remain somewhat more expensive, and require more precise current and heat management, than compact fluorescent lamp sources of comparable output.
What is a popular use for non-LED lighting?

After the collapse of the talks and a controversial visit by Likud leader Ariel Sharon to the Temple Mount, the Second Intifada began. Some commentators contend that the uprising was pre-planned by Yasser Arafat due to the collapse of peace talks. Sharon became prime minister in a 2001 special election. During his tenure, Sharon carried out his plan to unilaterally withdraw from the Gaza Strip and also spearheaded the construction of the Israeli West Bank barrier, ending the Intifada. By this time 1,100 Israelis had been killed, mostly in suicide bombings. The Palestinian fatalities, by 30 April 2008, reached 4,745 killed by Israeli security forces, 44 killed by Israeli civilians, and 577 killed by Palestinians.
