Limelight (also known as Drummond light or calcium light) [1] is a non-electric type of stage lighting that was once used in theatres and music halls. An intense illumination is created when a flame fed by oxygen and hydrogen is directed at a cylinder of quicklime ( calcium oxide ), [ 2 ] due to a combination of incandescence and ...

In the first hour, a five cell penny battery is able to provide about 5 × 10 −4 watts. Each cell is defined as a stack of a zinc penny, matboard, and a copper penny. Each cell can provide about 0.6 volts. Indicating that to power an LED light, needing 1.7 volts, only three cells need to be used.
The Tyndall effect is seen when light-scattering particulate matter is dispersed in an otherwise light-transmitting medium, where the diameter of an individual particle is in the range of roughly 40 to 900 nm, i.e. somewhat below or near the wavelengths of visible light (400–750 nm).
