1.Technology outline of EEFL
The EEFL (External Electrode Fluorescent Lamp), UVB EEFL differs from other fluorescent lamps, with its electrodes outside of the Lamp. External electrodes power the electric field in the lamp, then making plasma come into being, The light source of this Lamp is Plasma which is derived by External electrode of electric field inside the Lamp. Because of this technology, this EEFL, UVB EEFL does not generate heat itself and enhances the lifetime and the illumination stability incredibly and improves brightness efficiency. This EEFL is absolutely next generation of fluorescent Lamp for lighting. Features of EEFL. GLASS　COLD: BKU, Excel lent absorption of 313nm uv, Low solarization, Good sealing to kovar and molybdenum, Good sealing to BFK

2.Features of EEFL
(1) 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, parallely connected EEFL can be driven by one ballast. (2) 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.
