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

American standard metal halide lamps and metal halide ballasts different European standard, European standard metal halide or mercury lines available sodium line, you can add triggers inductively ballast; while the American standard metal halide lamp should configure a dedicated The CWA ballast, ie ahead of the peak-type (magnetic flux leakage boost) ballast, otherwise it will cause difficulty in starting, lower light efficiency, so that the color temperature instability, reduced lamp life.
As long as the European standard metal halide or high pressure sodium lamp ballast coupled with mercury ballast plus flip-flops and compensation capacitor 220V 50Hz power line in our work reliably. European standard metal halide lamp according to the start pulse peak voltage can be divided into two kinds of start pulse amplitude 0.6KV-1.5KV such as HPI lamps, another 4.0KV-5.0KV as HQI-T metal halide lamp. American Standard Metal Halide Metal Halide not use electrical configuration of European standard, European standard metal halide lamps in the circuit to obtain the minimum start rms voltage (≤ 240V) can not meet the American standard metal halide lamps for electrical requirements, So America must CWA underlying metal halide bulb lighting circuit configuration (ballast type the LC peak magnetic flux leakage boost ahead of ballast, the output voltage RMS and light form factor to meet the requirements), in order to ensure the bulbs work.
If the metal halide lamp not match with MH ballast.it will appear the following questions:
1, easy to burn out bulbs
Because the United States has triggered the inner tube beacon light pole, when the lights point to normal after power high-brightness and then re-transmission, because light bulbs can not immediately start the trigger pressure generated by high-pressure lamp will trigger electrode and the main electrode lead burned.
2, start difficulties, severe shorten lamp life
Due to start lamp lighting circuit does not meet the requirements, so there is some light bulbs at the beginning or during the life of the lamp does not start, showing the inner two lights glow discharge between the electrodes is always, or a few minutes to ten minutes to start, like this lamp life only a few days to a few weeks, the situation in light of the batch start-up performance slightly worse, or in the case of low grid voltage is more common.
3, the lamp power, luminous efficiency, color temperature greater impact
Can be drawn through the relevant test of two lighting circuit power, luminous efficiency, color temperature change, the test can be seen in the change in this circuit than in large multi-lighting circuit LC. So unreasonable electrical configuration not only damages the interests of users, resulting in a waste of resources, but also affect the energy-saving application.
