Our electronic low pressure sodium ballast adopts the method of high frequency AC output to ignite the LPS lamp, makes the LPS bulb life extended by at least 1.5 times than that using the magnetic ballast . The efficiency is also improved by at least10 percent. our LPS electronic ballast including the DC(12V-24V-36v)and AC(220v-110v) series. The DC series can be driven simply by solar energy. It is a great breakthrough in solar power application. In solar street lighting system, our electronic low pressure sodium ballast makes it possible that: the solar energy as the sole power supply for street light, no electricity at all! Till now, they are successfully applied in more than 2000 solar LPS street lamps in the whole world Solar lighting system and solar street lighting system Electronic ballast for low pressure sodium (LPS) lamps (AC110V-220V, DC12V-36V, 18W-180W) Electronic ballast for high pressure sodium (HPS) lamps (AC110V-220V, 35W-750W) Electronic ballast for metal halide (MH) lamps (AC110V-220V, 35W-750W) Electronic ballast for DC fluorescent lamps and UV lamps Various HID lamps and lighting fixtures with electronic ballast included OEM of the above products electronic HID ballast: Electronic Metal Halide Ballast, Electronic High Pressure Sodium Ballast, Electronic Fluerescent ballast.
