Fluorescent lamp
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 ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow. A fluorescent lamp converts electrical energy into useful light much more efficiently than incandescent lamps. 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.

Evenzo vragen mensen,What is the difference between CCFL and led TV?
TVs using full-array LED backlighting make up a chunk the high-end LCD TV market, and with good reason — with more precise and even illumination, they can create better pictures than CCFLs LCD TV were ever able to achieve. Plus, they’re less of a power drain than CCFL LCDs were.
What is the difference between LCD and led TV?
Despite having a different acronym, an LED TV is just a specific type of LCD TV. The proper name would actually be “LED-backlit LCD TV,” but that’s too much of a mouthful for everyday conversation, so people generally just refer to them as LED TVs.
