China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

Gas discharge lamp:
High Intensity Discharge pressure mercury lamp, metal halide lamp, high pressure sodium, etc. in general. These lamps high power, high luminous efficiency, long life, compact structure, small size. Mostly used for roads, squares, playgrounds, outdoor lighting, etc., but also for middle and high ceiling factories, gymnasiums, auditoriums and large shopping malls indoor lighting.
① high-pressure mercury lamp: include fluorescent high pressure mercury lamp and self-ballasted high pressure mercury lamp, power from 50 watts to 1000 watts, luminous efficiency of 40 to 50 streams / W, color rendering index of 40 to 45, the rated life of 5,000 hours.
② Metal halide lamp: high-pressure mercury lamp similar, the increase in metal halide arc tube, the light-emitting efficiency increased to 60 ~ 100 flow / W, color rendering index increased to 60 ~ 85, the rated life of 7,000 to 10,000 hours.
③ HPS: high-pressure sodium vapor discharge lamps, light golden white, luminous efficiency of up to 90 to 140 streams / W, color temperature of 2000 to open about poor color, color rendering index of 20 to 25, rated life of 12,000 hours, the power 35 to 1000 watts.
Low pressure sodium low-pressure sodium vapor discharge lamps, light was pure yellow, luminous efficiency of up to 130 ~ 175 Flow / watt, power of 18 to 200 watts, poor color, suitable for road lighting.

HID lamp is a high-pressure discharge lamp, the discharge of the "V a security" Performance negative resistance characteristics, so the lamp operating circuit to be connected to current limiting devices, which are commonly known as HID ballasts. HID lamp condition most of the work in the exchange, the use of device as the reactance ballast. There are different types of HID lamps, according to the type of light and its applications, can be configured with different forms of ballast circuit and lamp ballast circuit in order to achieve the best match. As a general lighting HID lamps commonly used in high-pressure mercury lamp, high pressure sodium and metal halide. HID lamps are high pressure mercury lamp light source earliest development, product performance and stability, supporting the ballast circuit is relatively mature.
