Screw the electronic ballast into the fixture, in the same place where the magnetic one was. How do light ballasts work? Don't worry: the tombstone replacements, like the ballast rewiring in the first place, is a quick, simple task. These ballasts are available in either instant start or programmed start ignition for extended lamp life in frequent switching applications such as those where occupancy sensors or motion detectors are being used. Ballast-compatible or plug-and-play LED tube lamps directly replaces fluorescent tube lamps without the need of changing any circuit on the lighting fixture. For a simplified overview of how a light ballast works as part of a series of in-fixture lighting connectors, think of it as being a two-job component.It gives a boost when we want to arc the light and power it on, then pulls back this initial high current flow to a more sedate level once lit. Less advanced in their design than electronic models, some magnetic ballasts can’t function without the aid of a starter. In a fluorescent lighting system, the ballast regulates the current to the lamps and provides sufficient voltage to start the lamps. If the mercury gas is heated sufficiently, it’ll conduct the current, generate light and then remain lit. To achieve full rated light output and rated lamp life from a fluorescent lighting system, a ballast’s output characteristics must precisely match the electrical requirements of the lamps it operates. If you sometimes hear your light buzz or see it flicker, it’s this changing flow of current that’s causing it. 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. Remove any covers, case, lenses, or lamps that block your access to the ballast and set them aside. Separate starters are only found in older control gear, so if a fixture is less than 15 years old it probably won’t have a starter. Ballast-compatible, "plug and play," or "direct drop-in" LED tubes make upgrading to cost-saving, long-life LED technology easy: simply take the fluorescent tubes out of your fixture and put the LED tubes in. You have no items in your shopping basket. There is a risk of electrocution when changing a ballast so if you’re unsure ask an electrician to do the job for you. A multimeter is designed to measure electric current, voltage and resistance. A light fixture (US English), light fitting (UK English), or luminaire is an electrical device that contains an electric lamp that provides illumination.All light fixtures have a fixture body and one or more lamps. 4.6 out of 5 stars 370. The light fixtures in our homes are remarkably effective and may work for years with little attention other than replacing an occasional burned-out light bulb.Sometimes, though, a light fixture that's been working fine may suddenly develop a problem that requires diagnosis and repair. ballast - A device required by electric-discharge light sources such as fluorescent or HID lamps to regulate voltage and current supplied to the lamp during start and throughout operation. Switch start requires a wire wound magnet choke of ballast. 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, I had a constant hot attached to the previous wiring so the light would remain on 24/7. The heated gas causes components inside the starter to allow the full current into the filaments. This is the direction the lighting industry is headed in, so why not swap them sooner rather than later to optimise your space with better, quieter lighting? Because your home’s mains power has a higher voltage than the light needs to operate, the ballast gives the light a small boost of voltage to start and then just enough of a supply to stay running safely. Shop ballasts and a variety of lighting & ceiling fans products online at Lowes.com. Lighting fixtures and retrofit kits hard wire into an electrical system to supply light in indoor settings. $23.01 $ 23. If your light comes on immediately but takes a few seconds to get fully bright, it has a rapid-start ballast. Fixtures with traditional light technology (such as fluorescent or incandescent) do not include light bulbs. A ballast factor of <1 means that your fluorescent system will produce less light (lumens) than the reference ballast and a factor of >1 means it will produce more light. Now there’s more electricity coming in, the ballast starts to do its job of regulating it. But the alternating current powering a fluorescent light is constantly reversing itself, so the ballast only has to inhibit increasing current in a particular direction for a short amount of time. Free Shipping On All Orders Over £50 (+ VAT), The complete guide to ballasts for fluorescent lights. The light switch is turned on. But whenever we use electricity we must control it, otherwise we risk destroying the device and even putting ourselves in danger. GE UltraMax Proline Electronic Ballast, 120/277 Volt Instant Start Ballast, Ballast for Fluorescent Light (4) or (3) Lamp T8, Normal Ballast Factor, Compatible with F32T8/WM and F17T8. These ballasts were developed so lights could be turned on and operated at their brightest at the first flick of the switch. Inside both ends of the light are metal electrodes with filaments attached. So, at different stages of the lamp's life, different light levels will be produced. Because your home’s mains power has a higher voltage than the light needs to operate, the ballast gives the light a small boost of voltage to start and then just enough of a supply to stay running safely. Look at for these signs indicating that it’s your ballast: You can find out whether the issue is with the ballast, starter or the lamp with our guide - Easy Fixes for Slow to Start, Flickering or Faulty Fluorescent Tubes. For this reason, they’re commonly used in spaces where the lights are left on for long periods, such as offices, shops and warehouses. Yes, if you have a bit of technical know-how, although if you’re unsure it’s best to ask an electrician to do this for you as it can be a complicated job.

If the lamp fixture does have a starter, it will be obvious. Put it in a safe place until you're ready to use it again. A lighting ballast is a piece of equipment required to control the starting and operating voltages of electrical gas discharge lights. Used in older T12 and some T8 tubes, this method functions without a starter. 01. This is called the pre-heat method. Hello: I just had my T8 florescent light fixture (ballast) changed to use with LED bulbs. Once the arc is established, the ballast quickly reduces the voltage and regulates the electric current to produce a steady light output. Turn off the electricity to the fixture at the power breaker box.Before starting to work on the fixture, flip the light switch to … Get it as soon as Mon, Jan 4. This can an important consideration if you’re trying to figure out payback on a lighting upgrade. They are inexpensive and can be found at most electronics shop. LED fixtures are integrated luminaires with built-in … End users may have a first impression that it is the best alternative because it is straightforward to replace the fluorescent lamp without rewiring. In many T8 fixtures, the ballast is covered by a casing and the T8 tubes are on top of it, meaning you need to take out the tubes and unscrew the casing to get to the ballast. Replacing and Recycling Fluorescent Tubes Safely. The process for swapping out magnetic ballasts for electronic ballasts is pretty simple and straightforward. Older fluorescent light fixtures utilized a magnetic ballast to control the flow of electricity through the light bulbs. 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. Step 1 - Turn Off Electricity. Join over 70,000 people who receive weekly lighting tips, amazing offers and discounts. Use the wire cutters to cut the wires connected to the sockets. The ballast (sometimes called control gear) is a small device wired to the light’s circuitry which restricts the amount of electrical current travelling through it.
