Remove the headlamp assy by locating 2 anchor bolts at the top( 10mm socket req) and 3 at the bottom of the lamp. the ballast is directly underneath bezel held by 3 Phillips screws. routing of harness very important so be careful. reversal to install.
For your question, i see the ignitor means the Electronic Ballast. If you want test HID lamp electronic ballast, you can reference Lisun WT2000-HID HID Ballast Tester, this instrument is main for test HID lamp electronic ballast,
a compact electronic ballast in the base of the lamp
No, the ballast has to be matched to the lamp. 250 watt ballast, 250 watt lamp. Also be sure to match the lamp type to the proper ballast even though the wattage is the same. HPS ballast to HPS lamp, Metal halide ballast to metal halide lamp and mercury vapour lamp to mercury vapour ballast.
No. The lamp has to match the ballast. The lamp will not ignite if the wrong ballast is used.
Yes assuming the ballast is also for a metal halide lamp.
If the ballast on a fluorescent light blows the lamp will not work.
As in all electronics heat is the culprit..if a lamp is mounted (let us say at a ceiling in a warehouse the temperature at the ceiling area is always more than the ground level) and this becomes a cause for ballast failures. Voltage spikes and dips are also a reason for ballast failures. The ballast specifications should match with the lamp (undersizing it will also cause failures) eg. using a 32 watt ballst for a 40 watt lamp. Cheers. Chaterpilar
The electronic BALLAST is a circuit that limits the current through the fluorescent bulb to the design value. It also provides a pulse of high voltage to start the bulb conducting when it is switched on.
First you need to determine if it's the ballast that's bad or the emergency ballast. The emergency ballast can go bad and cause the bulbs not to work or not all of them to work depending on the lights wiring setup. Push the test button on the emergency ballast which should have a red glowing indicator light. If all the lights illuminate slightly, change the emergency ballast. It's best to buy the exact ballast for this repair. i.e. If it's a T8 3 lamp fixture. Buy a T8 3 lamp ballast not a 4. You can use a 4 in place of a 3 lamp, but the 3 lamp will be more user friendly. Easiest way is to note what wires go to what. Draw a diagram if you have to and just simply match them back up.
No. The bulb has to match the ballast wattage exactly. And you can't interchange different lamps (like metal halide) either. The ballast is specific to that wattage and lamp type. The bulb will either burn out quickly or just not work properly at all
Yes a T12 lamp socket will take a T8 tube. The T8 tube will not operate. The T8 ballast is an electronic ballast where as the T12 ballast is a magnetic type. If you are changing over fluorescent fixtures to the smaller T8 lamps then the ballast has to be changed and the end sockets have to be rewired. The schematic on how to do the rewire is on the electronic ballast's label.
Absolutely. Only you need connect together two wires coming from each lamp holder (shunt).
