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

High pressure sodium lamp demands on the power supply voltage, general volatility should not be greater than the positive pay 5%. Because the the sodium lamp tube pressure, power and luminous flux changes, with changes in supply voltage than other gas discharge lamp. When the voltage is increased, likely to cause the lamp tube pressure drop increases self-extinguishing. . . . When the voltage decreases the luminous flux will decrease. Light the mere mention of the poor. . . The solution is with the the corresponding specifications high pressure sodium ballasts, there is the supply voltage to ensure the smooth. . . .
