Ballast bypass type LED tube lights are generally slightly cheaper than Ballast Compatible. It reveals the components of the circuit as streamlined forms, and the power and also signal links in between the gadgets. opposite side of ballast as the LED Tube lamp only requires power at one end. These output wires provide the power to the lamps. Unlike pre-heat—where the filaments receive current via the starter only to heat the mercury gas—with rapid start, the ballast keeps a small amount of current flowing continuously through the filaments. However, it does use more energy. On this page, we will refer to a fluorescent light bulb as a lamp or tube. Twist the nut clockwise to combine the wires, making sure the nut is very tight. 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. Grounding is usually automatic if the light fixture is grounded properly. Locate The Ballast On The fluorescent Light Fixture. But whenever we use electricity we must control it, otherwise we risk destroying the device and even putting ourselves in danger. Feed the ends of the wire through the cable clamps and tighten the screws until the wire is secure. Besides rewiring of fluorescent fixtures, this is another method as for how to convert fluorescent fixture into the LED. The process that occurs inside a fluorescent light involves molecules of mercury gas being heated by electricity and made more conductive. Use the wire cutters to cut the wires connected to the sockets. 2. To purchase a new 300mm led tube replacement see our fluorescent tubes section. 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. I am looking for some advice about fluorescent ballasts replacements. There should have been instructions/wiring diagram with your new ballasts. This causes the mercury gas to become ionised—that is, charged in a way that enables it to conduct electricity. Remove the ballast from the tube lamp housing, and save the original wiring that connected to the 110VAC. 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. Fluorescent tubes require a ballast to operate. The wiring process of fluorescent tube lamp/light with Ballast, Starter is quite easy and simple.

If an old T12 lamp magnetic ballast is replaced with a newer T8 lamp and electronic ballast, the colors will probably not match. I purchased a GE proline ballast replacement for a two lamp flourescent fixture, 48" each lamp. Insert the LED bulb, and you got your economical LED bulbs. Electricians usually refer to a light bulb as a lamp. If you sometimes hear your light buzz or see it flicker, it’s this changing flow of current that’s causing it. Connect the power and neutral wires to the corresponding ballast wires. Note: There will be four to eight wires coming out of the ballast. Fluorescent Light Ballast (Be sure to get one that’s for the specific bulb that your light requires. All you need to do is remove the ballast from your fixture (say goodbye to failing ballasts for good!) and wire the main power directly to the lamp’s sockets. Rapid start ballasts can only be wired in series according to the diagram on the ballast. Group the matching wires from ballast to light according to your ballast's manual; Feed both ends of matching wire (one from the ballast, one from the light) into the wire nut. See the diagrams for clarification. Cut back the insulation on each wire about 1 inch and then twist the copper wires a couple of times to make a tight bundle. 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. Easy Fixes for Slow to Start, Flickering or Faulty Fluorescent Tubes. Use wire nuts to connect the socket wires. If you’re more of a reader, we’ve also made a one-page instruction sheet for retrofitting 8ft fluorescent fixtures to LED . If your light fixture has two or more fluorescent tubes, it’ll likely use another different method known as rapid-start. Fluorescents have different color renderings that incandescent lamps can’t offer economically, such as plant lights for a greenhouse. Electrical pliers. Instant start ballasts can only be wired in parallel according to the diagram on the ballast. A metal ballast mounted to the metal light fixture will automatically ground the ballast. "Follow the colore-coded wiring diagram" was the recommendation, yet after connecting all like colors on the new ballast to the fixture, all I got was a delayed, dim light at the base of each fluorescent bulb. How does a fluorescent light ballast work? Inside both ends of the light are metal electrodes with filaments attached. 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.

Strip the load and neutral wires from the ˚rst set of wires that were cut. They are inexpensive and can be found at most electronics shop. It’s worth spending a bit more in order to save yourself money and effort in the future. Need of Starter in fluorescent light There are two basic types of ballasts. If a ballast has a ground terminal on it, a ground wire should be connected to it. The common wire(s) connect to all of the lampholders on the other side of the tubes. 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. When magnetic ballasts break, it is often blamed on the bulb. And when I electrically connect everything here, there are a few more wires to deal with under the wire nuts… but all LED light tubes will now be powered (via standard house AC – no ballasts) from one side. Cut the new wires to length and then connecting them accordingly (see diagrams) with wire nuts. Cut out the Red, Blue and yellow wires near each ballast. Whether going with Ballast Compatible or Ballast Bypass, it's a good idea to remove the ballast from the light fixture in order to save an extra 10% of energy per fixture. Fluorescent Light Fixture Electrical Question: Can a light fixture with an electronic ballast share the same circuit with a light fixture with a magnetic one? In order to ensure that the issue is with the ballast, you will want to test it with a multimeter. There should also be a red and blue set of wires on the ballast. Find the white wire coming from the main service panel and connect it to the white wire on the cable using a wire nut. Lights which are operated with a high frequency ballast do not flicker, but instead light up instantly due to the frequency being much quicker. Fluorescent Ballast Labels. A multimeter is designed to measure electric current, voltage and resistance. Than remove the 10mm nuts 1 … 3. The light switch is turned on. Fluorescent lights use either an electronic or a magnetic ballast. Screw the electronic ballast into the fixture, in the same place where the magnetic one was.

How to wire a replacement ballast with different wiring? With some 3 and 4-lamp programmed start ballasts (wired in series-parallel), if a single lamp in one branch fails, the lamp(s) in the parallel branch will continue to operate. Older magnetic fluorescent ballasts are usually rapid start and wired in series. 2. If the mercury gas is heated sufficiently, it’ll conduct the current, generate light and then remain lit. We understand sometimes things go wrong and we aim to make returns as simple as possible. Newer electronic ballasts are instant start (wired in parallel), rapid start (wired in series), programmed start (wired in series-parallel, dimmable and CFL ballasts. When that UV light (which is invisible to the naked eye) interacts with the coating of phosphor powder inside the tube, it glows and produces the light we see and use in our homes. This is called the pre-heat method. 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. If the ballast looks burnt, it definitely needs replacing, Insert first probe of the multimeter to the wire connecting the red wires together, Touch the second probe to the green and yellow colour wires, If the multimeter doesn’t move, it means the ballast is dead, If the multimeter is still working, the multimeter needle should move across to the right, Open fixture and remove the bulb and ballast casing, Using the wire cutters, cut both power (brown) and neutral (blue) wires coming into the fixture. Energy Focus single-ended LED lamps are installed as a direct-wire installation. The new screw-in fluorescent light bulbs (CFL or compact fluorescent lights) have a built-in ballast in their base that works to start the bulb when you turn on the light.
