Metal vapor arc discharge lamp application in matters to your focus from the mercury and sodium is unique discharge material, so high pressure mercury lamp and high pressure sodium lamp the exclusive functionality. Street light source notes are as follows:

A, light bulbs should be utilized using the similar specifications with the light ballast, otherwise the bulb won’t be able to start out or shorten the lifestyle span.
B, inside the use of the light bulb to go out, in case the power supply voltage fluctuations are certainly not significant, ballast injury to other elements of the usual, re begin pilot, if it can be nevertheless burning, the bulb cannot proceed to implement, really should be replaced by a whole new light bulb.
C, electrical power supply voltage needs to be relatively secure, transient improvements should not be as well substantial. If your power provide voltage suddenly drops 10%, high pressure mercury lamp will extinguish; high pressure sodium lamp energy shortage because of exhibit of lanterns, light output reduction. When the voltage is too high, it is going to shorten the support lifestyle in the lamp.
D, the lamp is usually lit at any position, nevertheless, the amount of high pressure mercury lamp ignition, luminous flux output will likely be decreased by 7%, along with the light bulb to self extinguishing. The high-pressure sodium lamp photoelectric parameters unchanged.
E, the inner space can’t be too smaller, need to have fantastic heat dissipation disorders, to be able to impact the lamp existence. High pressure sodium lamp is not user friendly single parabolic and reflection type lamp, the lamp will most of the light reflection for the lamp tube, lamp voltage rise, maximize the lamp electrical power, shorten the lamp existence.
F, high pressure mercury lamp outside broken needs to be dealt with in time, the substitute from the new worldwide, so a whole lot of ultraviolet radiation burns and eye skin.
G, restart time. Within the application of high pressure mercury lamp swiftly ignited, can be put in to ensure the electronic ignitor, instantaneous start out.
