Web1 day ago · Fluorescent proteins like mScarlet3 are attached to cells to help scientists observe the movements and interactions of stem, cancer, and other live cells under a microscope. Fluorescent green proteins were the first to be developed, followed by blue, turquoise, and yellow variants before a red fluorescent protein was discovered in the … 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 … See more Fluorescent lamps come in many shapes and sizes. The compact fluorescent lamp (CFL) is becoming more popular. Many compact fluorescent lamps integrate the auxiliary electronics into the base of the lamp, allowing them to fit into a regular light bulb socket. See more Frequent switching Frequent switching (more than every 3 hours) will shorten the life of lamps.
