What is a ballast Ignitor?
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 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 is Ignitor work?
When the ignition key is turned on, a low voltage current from the battery flows through the primary windings of the ignition coil, through the breaker points and back to the battery. As the engine rotates, the distributor shaft cam turns until the high point on the cam causes the breaker points to separate suddenly.
Is a ballast the same as an ignitor?
1.888. JLEVISW. On an OEM headlight, the ballast and igniter are integrated. The igniter functions as the firing mechanism for the bulb, the ballast functions as the power source to convert the car’s power into a usable source for the xenon bulb.
What is illumination Ignitor?
Ignitors An ignitor is a starting device that generates voltage pulses to start a discharge lamp. This normally happens after the ignitor has tried to start the lamp a few times, and for metal halide lamps this is generally after approximately 15 minutes.
How do I test a ballast with a multimeter?
To measure it, set your digital multimeter to around a thousand ohms resistance setting. Connect the black leads to the white ground wire on your ballast. Afterward, test every other wire with the red lead. When you do this test, a good ballast will return an “open-loop” or max resistance.
How many plants can a 1000 watt HPS grow?
Some growers have boasted of growing about 6 to 9 plants using 1000 watt HPS. Some even grow smaller plants while using the SCROG and SOG technique to manage space.
Can you dim HPS lights?
These days, there are many brands and models of HID (HPS and CDM / CMH) grow lights that have the facility to be dimmed. It tends to be only the cheap ones (with magnetic ballasts) that do not. Nearly all digital ballasts have a control for dimming, and many also have a “boost” function too.
Are ballast and choke same?
A choke is an inductor designed to have a high reactance to a particular frequency when used in a signal-carrying circuit. An electrical ballast (sometimes called control gear) is a device intended to limit the amount of current flowing in an electric circuit.
