This is called the pre-heat method. Inside the fluorescent fixture tie the two black wires and the two white wires of both ballasts together. You should find a small grey cylinder plugged into the light fitting. When a rapid start ballast (wired in series) operates multiple lamps and one lamp fails, the circuit is opened and the other lamps will not light. You need to cut these wires close to the ballast; these are input wires because they send power to the fixture. This one is a T12, while this one is T8.) Twist the nut clockwise to combine the wires, making sure the nut is very tight. Connection instructions led tube light installation ballast bypass cut the load and neutral wires from the ballast leaving a sucient amount of wire to connect back to the 110 vac power source. Screw the switch back to the electric box and re-attach the switch cover. Some older electronic ballasts employ the rapid-start method described above, while newer and more advanced models use what are known as instant-start and programmed-start. The process that occurs inside a fluorescent light involves molecules of mercury gas being heated by electricity and made more conductive. Fluorescent Light Ballast (Be sure to get one that’s for the specific bulb that your light requires. Using more sophisticated circuitry and components, ballasts can control the current running through fluorescent lights with greater precision. A ground wire from the power source should be connected to a light fixture. Grounding a ballast is very important. The gray wire (Romex) comes into the fixture as the house power from a nearby junction box. The fixture here uses a 2-bulb series ballast that gets replaced with a 2-bulb parallel ballast. Use the wire cutters to cut the wires connected to the sockets. The current enters the filaments but at this point is too low to fire up the light, though it is enough to heat the gas (neon or argon) inside the starter. GERS … If your light fixture has two or more fluorescent tubes, it’ll likely use another different method known as rapid-start. The wiring process of fluorescent tube lamp/light with Ballast, Starter is quite easy and simple. Without a ballast to control this, there would be too much current for the light to take, and it would burn out and possibly even catch fire. Before you go to the trouble of replacing the ballast, you should determine if a bad ballast is indeed the likely cause of the problem. High frequency control gear is a modern single ballast that performs the functions of all the different components in the standard switch start circuit. Insert the LED bulb, and you got your economical LED bulbs. Switch start is the control gear that has been used by the industry for years. Connect each of the blue ballast wires to the each of the two blue lampholder wires. While this may sound bad, it's actually quite easy to wire a T8 ballast and by doing so, you'll be able to avoid replacing the entire fluorescent fixture. Cut the Old Ballast Wiring. Rather than pre-heat the electrodes, the ballast uses a high-voltage boost (around 600 volts) to heat and light the filaments and then the mercury gas. Remove the case, lamp, and any cover that prevents you from reaching the ballast. Run a length of two-conductor wire from the existing fluorescent fixture to the new fixture. The process for swapping out magnetic ballasts for electronic ballasts is pretty simple and straightforward. Strip the load and neutral wires from the ˚rst set of wires that were cut. A magnetic ballast (also called a choke) contains a coil of copper wire. This is what causes some old fluorescent lights to flicker. I am looking for some advice about fluorescent ballasts replacements. The wiring process of fluorescent tube lamp/light with Ballast, Starter is quite easy and simple. Ballast Wire Colors. These rely on the principles of electromagnetism, in that when an electrical current travels through a wire, it naturally generates a magnetic force around itself. Individual ballast wires each connect to a lampholder on one side of each tube. They’re often a feature of lighting that’s activated by motion-detection sensors (for example, toilets in workplaces or public venues) and allows the fluorescent light to last for a long time. What’s the difference between switch start and high frequency control gear? Easy Fixes for Slow to Start, Flickering or Faulty Fluorescent Tubes.
