A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, to produce ultraviolet and make a phosphor coating in the lamp glow.

A fluorescent tube (or fluorescent lamp) is operated with gas-discharge principle that uses electricity to excite mercury vapor. Electricity excites mercury atoms which then produces short-wave ultraviolet light. The ultraviolet light then causes a phosphor coating to fluoresce to produce visible light. Compare to the incandescent lamps, fluorescen...
Luminous efficacy
The efficiency of fluorescent tubes is much higher than that of incandescent lamps, which means more input power can be converted to visible light by using fluorescent tubes than incandescent lamps. Fluorescent lamps use 25%-35% of the energy used by incandescent lamps to provide the same amount of illumination.
Life
Typically a fluorescent tube lasts about 10 times (15,000 - 30,000 hours) that of an equivalent incandescent lamp. The longer life may also reduce lamp replacement costs, providing additional saving especially where labour is costly.
Lower luminosity
Compared with an incandescent lamp, a fluorescent tube is a more diffuse and physically larger light source. In suitably designed lamps, light can be more evenly distributed without point source glare as seen in an undiffused incandescent filament.
F = Fluorescent T = Tubular lamp shape 8 = lamp diameter in 1/8 inch increment e.g. T5 = 5/8 inch = 16 mm T8 = 8/8 inch = 1.0 inch = 26 mm T10 = 10/8 inch = 1.25 inch T12 = 12/8 inch = 1.5 inch = 38 mm Fluorescent lamps, T12, & T8, have long been used as energy-efficient lamps for general lighting. New generation of T5 fluorescent lamps with 16mm d...
The standard wattage of the T5 lamps range from 14W, 21W, 28W to 35W. High output versions are also available for some special applications. Operated with high frequency electronic ballasts, these new lamp types fulfill the principle of cost-effectiveness. T5 lamps have the highest luminous efficacy of about 110 lm/W, when compared with T12 and T8 ...

螢光燈 （英語： Fluorescent lamp），或稱 日光燈 、 燈管 、 螢光管 、 光管，是一種照明裝置，屬於 氣體放電燈 的一種。 它使用 電力 在 氬 或 氖 氣中激發 水銀 蒸氣，形成 電漿 並發出短波 紫外線，紫外線被 磷光體 吸收後，磷光體會發出可見的光以照明，這樣發出可見光的方式屬於 螢光。 一般的螢光管以 玻璃 製造，在兩端裝有插口以連接電源及固定螢光管的位置。 與 電燈泡 不同，螢光管必須設有 安定器，與 啟動器 配合產生讓氣體發生電離的瞬間高壓。 為了取代傳統 白熾燈，近年來發展出將燈管、 安定器 、 啟動器 結合在一起，配合使用白熾燈燈座的改良型螢光燈泡，稱為 省電燈泡，可以在不更換燈具基座的情況下，直接取代 白熾燈 使用。 原理.
