17 Facts About Fluorescent lighting

Fluorescent lighting lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light.

Fluorescent lighting made the important observation that the glow in the tube shifted position when in proximity to an electromagnetic field.

Fluorescent lighting went on to apply thin coatings of luminescent materials to the surfaces of these tubes.

Fluorescent lighting invented a fluorescent lamp in 1896 that used a coating of calcium tungstate as the fluorescing substance, excited by X-rays, but although it received a patent in 1907, it was not put into production.

From 1904 onwards Moore's Fluorescent lighting system was installed in a number of stores and offices.

Neon tube Fluorescent lighting, which includes the use of argon and mercury vapor as alternative gases, came to be used primarily for eye-catching signs and advertisements.

Neon lighting was relevant to the development of fluorescent lighting as Claude's improved electrode overcame "sputtering", a major source of electrode degradation.

Fluorescent lighting systems spread rapidly during World War II as wartime manufacturing intensified lighting demand.

Fluorescent lighting lamps are negative differential resistance devices, so as more current flows through them, the electrical resistance of the fluorescent lamp drops, allowing for even more current to flow.

Fluorescent lighting lamps are never operated directly from DC for those reasons.

Halogen lighting is 3000 K Fluorescent lamps are manufactured to a chosen CCT by altering the mixture of phosphors inside the tube.

In other countries, residential use of fluorescent lighting varies depending on the price of energy, financial and environmental concerns of the local population, and acceptability of the light output.

Fluorescent lighting lamps convert more of the input power to visible light than incandescent lamps.

Fluorescent lighting lamps give off about one-fifth the heat of equivalent incandescent lamps.

Fluorescent lighting lamps require a ballast to stabilize the current through the lamp, and to provide the initial striking voltage required to start the arc discharge.

Fluorescent lighting lamps are a non-linear load and generate harmonic currents in the electrical power supply.

Fluorescent lighting tubes are long, low-luminance sources compared with high pressure arc lamps, incandescent lamps and LEDs.
