The Light Spectrum and its Relationship with Fluorescence

WebMedium light (PPF: 150-250 umol m-2s-1 / 250-1,000 foot-candles / 15-20 watts) A medium-light plant would be suitable for east-facing windows or located near a west-facing window, but out of direct light. You would need artificial lighting for starting seeds in medium light. Like the low light plants, these plants will not dry out as quickly. Fluorescent lamp tubes are often straight and range in length from about 100 millimeters (3.9 in) for miniature lamps, to 2.43 meters (8.0 ft) for high-output lamps. Some lamps have the tube bent into a circle, used for table lamps or other places where a more compact light source is desired. See more 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, which produces short-wave See more The fundamental mechanism for the conversion of electrical energy to light is the emission of a photon when an electron in a mercury atom falls from an excited state into a lower See more Fluorescent lamps come in many shapes and sizes. The compact fluorescent lamp (CFL) is becoming more popular. Many compact … See more Frequent switching Frequent switching (more than every 3 hours) will shorten the life of lamps. Each start cycle slightly erodes the electron-emitting surface of … See more Physical discoveries The fluorescence of certain rocks and other substances had been observed for hundreds of years before its nature was understood.
