How do you test a metal halide ignitor?
Check the ballast output with a voltage tester. Turn on the lamp and touch the ends of the tester leads to the lamp electrodes with the bulb in place, then remove the bulb and make the same test. You should get voltage readings in both cases that agree with the output specified on the label.
How do you test an HPS Ignitor?
Metal halide lamps do not require an ignitor to start, so the test for a failed ignitor for an HPS lamp is to screw in a metal halide bulb of the same wattage and see if it starts. If the MH lamp starts and a new HPS lamp does not start, the ignitor probably needs to be replaced.
What does an igniter do in a ballast?
Venture Lighting, Ballast Technical Section – Ignitors. HID lamp ignitors provide a brief, high voltage pulse or pulse train to breakdown the gas between the electrodes of an arc lamp.
How do you test a metal halide capacitor?
The proper test procedure is as follows: – Disconnect the Metal Halide, High Pressure Sodium or Pulse Start capacitor from the circuit and discharge it by shorting the terminals or wires together. – If the meter indicates a very low resistance then gradually increases, the capacitor does not require replacement.
How do I know if my metal halide ballast is bad?
Signs that a Metal Halide light bulb or ballast needs replaced: The lamp appears to be a different color, or are turning pink.
Is ballast and ignitor same?
It carries the high current of the lamp and limits it to rated current while running. Ballast also has terminals which give voltage to igniter. Gas lamps have to be given a HV pulse every cycle to strike and maintain the arc. An igniter is an electronic pulse circuit used for this job.
How does an ignitor work?
When the button on a Piezo electric ignitor is pressed, a spring loaded hammer strikes quartz in order to create a spark. This is the typical process used in such lighters. This creates the necessary amount of voltage to generate a spark.
How many volts go to a hot surface ignitor?
A hot surface igniter can burn out at approximately 132 V. Even voltages in excess of 125 V may reduce igniter life. If high voltage is present, the power company should be requested to lower the power.
What is the output voltage of a metal halide ballast?
Mercury and metal halide, 175-400 watt: 135-140 volts.
What causes a high pressure sodium light to go on and off?
A high pressure sodium lamp cycling on and off usually indicates the lamp has reached the end of its normal life.
