Due to the declining LED price and environment-friendly energy policies, CO2 emission reduction and energy-saving, the LED lighting industry is accelerating rapidly. In particular, the needs for LED lamp, replacing the existing fluorescent lamp without exchange luminaire or driver circuits, are also rapidly increasing. Therefore, replacement for T8 fluorescent lamp, LED T8 lamp was developed and standardized. However, except LED T8 lamps, other lamps’ regulations or standards were not enacted. Also, the stability of fluorescent lamp substitutable LED lamp is low due to the difference in electrical characteristics and mismatch between the existing fluorescent lamp ballast and LED lamp. Therefore, many are struggling while developing fluorescent lamp substitutable LED lamp. In this paper describes the properties of existing fluorescent lamp ballasts and the considerations while developing fluorescent lamp substitutable LED lamp : demonstrating its validity by experiments the developed fluorescent lamp substitutable LED lamp prototype.
