This EEFL (External Electrode Fluorescent Lamp) tube differs from other fluorescent tubes with its electrodes outside of the tube. The external electrodes power the electric field in the tube, then making plasma come into being. The light source of this light tube is plasma, which is derived by external electrode of electric field inside the tube. Because of this technology, this EEFL tube does not generate heat itself and enhances the lifetime and the illumination stability incredibly and improves brightness efficiency. This EEFL tube is absolutely the next generation of fluorescent tube for lighting.

• Features of EEFL:
• To avoid negative impedance of common gas charge lamp, EEFL external electrode allow high frequency voltage function via capacitance coupling.
• As a result of this, parallel-connected EEFL can be driven by one ballast.
• EEFL is able to get long lifetime and high lighting stability, which is because its special working principle will cause much less heat than CCFL.
• Applications of EEFL.
• Large area LCD screen and large advertisement lighting box.
