Fluorescent light infrared spectrum
WebFluorescent lights can't be "fine-tuned" to red/NIR wavelengths; they are available as warm white, cool white, or full-spectrum, which mimics the spectrum and color temperature of … A fluorescent lamp converts electrical energy into useful light much more efficiently than an incandescent lamp. The typical luminous efficacy of fluorescent lighting systems is 50–100 lumens per watt, several times the efficacy of incandescent bulbs with comparable light output. 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 the cathodes; when all the emission material is gone, the lamp cannot start with … See more Physical discoveries The fluorescence of certain rocks and other substances had been observed for hundreds of years … See more The spectrum of light emitted from a fluorescent lamp is the combination of light directly emitted by the mercury vapor, and light emitted by the phosphorescent coating.

WebFluorescence is luminescence caused by electromagnetic radiation. Visible light can cause luminescence; shine a pure violet light at a ruby, and it will glow red, as it has absorbed the violet light energy and used it to create red light. But light-induced luminescence is uncommon and hard to see.
