To return your items, please e-mail [email protected] with your order number and we will send a returns number and return instructions to you. A fluorescent tube uses electricity to make mercury gas emit ultraviolet (UV) light. A metal ballast mounted to the metal light fixture will automatically ground the ballast. An electronic ballast is a device which is used to limit the current of a load such as tube light or fluorescent lamps. 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. Used in older T12 and some T8 tubes, this method functions without a starter. Note: There will be four to eight wires coming out of the ballast. Though this makes them energy efficient, it also shortens their life, as the surge of voltage every time they’re switched on damages them over time. However, it does use more energy. Remove the ballast from the tube lamp housing, and save the original wiring that connected to the 110VAC. If you sometimes hear your light buzz or see it flicker, it’s this changing flow of current that’s causing it. These ballasts were developed so lights could be turned on and operated at their brightest at the first flick of the switch. When replacing a fluorescent tube light with an LED tube light, the ballast becomes irrelevant, but … Remove the ballast from the. Step 3. Use wire nuts to connect the socket wires. This causes the mercury gas to become ionised—that is, charged in a way that enables it to conduct electricity. Compared to their magnetic counterparts, they’re smaller, lighter, more efficient and—by supplying power at a much higher frequency—less likely to cause flickering or buzzing sounds. The light switch is turned on. Older fluorescent light fixtures utilized a magnetic ballast to control the flow of Remove the wire nuts from the black and white wires connecting the ballast to. A fluorescent tube circuit includes a ballast, wires, lampholders, and the tubes. You need to cut these wires close to the ballast; these are input wires because they send power to the fixture. Rapid Start Lampholder Wiring 2 and 4 Lamps, Swap Terminals on Non-Shunted Lampholders, Wire colors for individual and common connections on fluorescent ballasts will vary depending on ballast type, brand, and the number of lamps they support. To regulate the current flowing throughout fluorescent lights, we use what’s known as a ballast. Circline fluorescent light ballast: Wire run through hole: If your fixture has a cover over the lamp(s) remove that. The common wire(s) connect to all of the lampholders on the other side of the tubes.

If a ballast has a ground terminal on … 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. The magnetic field produced by the wire traps most of the current so only the right amount gets through to the fluorescent light. Various parts can be replaced for switch start, rather than the whole unit, which could been seen as an advantage. Less advanced in their design than electronic models, some magnetic ballasts can’t function without the aid of a starter. Using more sophisticated circuitry and components, ballasts can control the current running through fluorescent lights with greater precision. To purchase a new 300mm led tube replacement see our fluorescent tubes section. Green - (NOT a ground wire) in this case is connecting the ballast to the second terminal on the same fluorescent lamp connector as received the white or neutral wire. 1. This is called the pre-heat method. And once more – good to go! If one lamp fails, the others can keep operating as the circuit between them and the ballast remains unbroken. This one is a T12, while this one is T8.) Fluorescent lighting is an effective way to light a large area. If your light fixture has two or more fluorescent tubes, it’ll likely use another different method known as rapid-start. Go to your breaker box … One advantage of the rapid-start method is that by providing a low, continuous current rather than a strong surge, it prolongs the life of the fluorescent light. Remove the old ballast by unscrewing the mounting screws. The socket lead wires (most likely red and blue-colored wires) are located on the other side of the ballast and connect to wires going out of the ballast to the sockets (which should be non-shunted sockets for T8 LEDs). Instant start ballasts can only be wired in parallel according to the diagram on the ballast. The fluorescent fixture has now been converted to LED light. If an old T12 lamp magnetic ballast is replaced with a newer T8 lamp and electronic ballast, the colors will probably not match. Because it’s only a gentle current, the light will glow quite dimly at first. You can return items to us within 30 days of receiving your order providing the goods are unused. You can find out how to do this safely with the guide Replacing and Recycling Fluorescent Tubes Safely. Now there’s more electricity coming in, the ballast starts to do its job of regulating it.
