The T-5 Lamps developed in 1996 is the high efficiency fluorescent lamps, the lamps voltage is high, and the lamps current small because the lamps are slender tube of 16mm diameter. And so, the electrical characteristics of the Ballast for the lamps are different from of the Ballast for T-10 or T-8 lamps. Therefore, the know-how of the exclusive Ballast for the T-5 fluorescent lamps should be as soon as possible. We described the electrical and optical characteristics of the Electronic Ballast for T-5 Circular Fluorescent lamps. The developed Electronic dimming Ballast for T-5 Circular Fluorescent lamps has the 45% energy saving effects than the T-10 lamps. And it has the promotion of the THD less than 10%, CF less than 1.5%, Flickering less than 5% and 99% power factor. And it is available for two T-5 Circular fluorescent Lamps dimming, 22W and 40W.
