Xenon (incandescent) - emit a warm natural light, and tend to be the less expensive, however, offer less brightness and have a shorter battery life than LED or HID lights. LED (light emitting diode) - are very durable, efficient and powerful. HID (high intensity discharge) - are extremely powerful and have a nearly white beam.
Ultra-high-performance lamp. An ultra-high-performance lamp, often known by the Philips trademark UHP, is a high-pressure mercury arc lamp. [1] These were originally known as ultra-high-pressure lamps, [2] [3] because the internal pressure can rise to as much as 200 atmospheres when the lamp reaches its operating temperature.
Sonoluminescence is the emission of light from imploding bubbles in a liquid when excited by sound. Sonoluminescence was first discovered in 1934 at the University of Cologne. It occurs when a sound wave of sufficient intensity induces a gaseous cavity within a liquid to collapse quickly, emitting a burst of light.

In addition to choreographing the wall's surging water, WET used 5,000 color changing LEDs to allow the 19-meter mosaic of light, lines, and color to morph throughout the day. [29] [30]
