49 Unexpected Facts About How To Test A Tube Light Starter | How To Tell If Fluorescent Starter Is Bad

• Some FS-2 starters such as from Philips may be illustrated online using an FS-4X photo (at Home Depot) ? Be sure to check the specifications in Watts marked on the starter itself. Some FS-20 starters can also be used with 25W straight fluorescent bulbs: check the manufacturer’s specifications. Starter operating tip - reverse the starter: if you install a new fluorescent bulb starter and the lamp still isn’t working well, or not lighting at all, try removing the starter, rotating it 180 degrees and re-installing it, essentially “reversing” its position in the starter socket. - Source: Internet

• How to find and replace your starter Turn off the light at the switch and turn off the power supply to the light via the circuit breaker. Remove the tube from the fixture, as the ballast is usually found behind the bulb or between the bulbs in a fitting with more than one tube. The ballast will usually have a cover on it so remove the ballast cover using a screwdriver and check the ballast, which is usually a rectangular shaped grey or black box, to see if it’s leaking oil or if it looks burnt. Firstly, check all the wires are connected properly as loose wires could cause the ballast not to work properly, if the wires are properly connected, then the problem is likely to be with the ballast itself. Ballasts come in all shapes and size so if you do need to buy a new one, check the measurements carefully when buying online, or take the old ballast into the lighting shop with you. - Source: Internet
• I acknowledge that replacing all the bulbs is not the most economical solution…it’s just a practical viewpoint from someone (me) who has been paid to do this type of work for others (you). Fluorescent tubes are an overall economical choice when compared to the alternatives! It just makes more sense to change both tubes at once. To receive a second service call in a month because one of the other bulbs has gone bad is neither desirable from the customer’s point of view ($$) or mine (pride in a job done right). - Source: Internet
• When shopping for a new fluorescent tube, compare lumens (brightness), wattage and life expectancy. Most manufacturers print this information on the cartons. Bulbs typically last for at least a year, often much longer. - Source: Internet
• Sadly, there is no way for the home handyman to troubleshoot a starter except by replacing it. Before replacing the existing starter, though, be sure it is securely seated in the base by removing and then reinstalling it. A starter is installed by pressing it into the socket and then turning clockwise till it locks in place. To remove a starter, press in and turn counterclockwise… then withdraw the starter. - Source: Internet
• Conventional fluorescent tubes need a starter. This starter provides ignition voltage. Naturally, this isn’t necessary for LEDs, so the ignition voltage is superfluous. If you want to replace a traditional fluorescent bulb with an LED, then you must install a dummy starter or bypass the standard starter manually. - Source: Internet
• Knowing how to troubleshoot fluorescent light fixtures can be incredibly useful. Although most of the problems are reasonably easy to fix, discerning the cause of an issue can be troublesome. The most common problem with fluorescent lights is flickering tubes. In most cases, flickering fluorescents are caused by a problem with one of three things: the starter, the tubes, or the ballast. - Source: Internet
• One of the most common (and most expensive) causes of problems with fluorescent lights is the ballast. Sometimes, it can be cheaper to replace the entire light fixture than it is to replace a ballast, so talk to an electrician about the best solution for your needs. The ballast is what regulates the current running through the tubes in order to ensure that they produce a balanced amount of light. When it malfunctions or wears out, the lights can begin to darken or flicker. If you have exhausted all other possibilities as to what the problem is with your fluorescent light, then the issue is likely stemming from the ballast. - Source: Internet

• Starters are rated by wattage to the bulbs they will control. If you have a fixture but have misplaced the starter, write down the wattage of any of the fluorescent tubes and take that information to the hardware store, lest you be scolded by the mean clerk and sent home without supper… or a starter. - Source: Internet
• Fluorescent starters are used in several types of fluorescent lights. The starter is there to help the lamp light. When voltage is applied to the fluorescent lamp, here’s what happens: - Source: Internet
• Fluorescent light starters install into preheat-start magnetic fluorescent ballasts. They provide a small amount of electricity that ionizes the gas inside a fluorescent bulb, allowing the gas to conduct electricity so that the bulb can light. Starters should be replaced when fluorescent lights begin to flicker or fail to light. - Source: Internet
• Fluorescent lights are a great way to get a lot of long-lasting light into a space, but they can also be a major hassle. Fixing them requires extra steps, they are harder to install than regular fixtures, there are often multiple explanations for problems, and even disposing of burnt out light tubes requires extra care. At Expert Electric, we know how to troubleshoot fluorescent lights in order to ensure that our clients’ light fixtures perform as well as possible. - Source: Internet
• When inspecting the ends, examine the glass portions. A brownish tint is normal on tubes that have been in use for some time. Tubes whose ends are blackened usually are wearing out. - Source: Internet
• Sometimes, fixing a fluorescent light tube is as simple as jiggling or twisting the faulty tube, as the problem might be caused by a loose connection. If any of the tubes are dark near the ends, it is likely that they are reaching the end of their lifespan and need to be replaced. The best way to test a tube to see if it is the culprit is to remove it and plug it into a different fixture that you know works. In fixtures with multiple tubes, one faulty tube could cause flickering in the other tubes, so make sure that you test them before buying all new fluorescent tubes. - Source: Internet
• In case of new fluorescent tube, this fault automatically cures after few days. Burn out electrodes This fault occurs due to short-circuit of the choke. Test with a new choke. The brightness of the fluorescent lamp decreases. Low power supply voltage. - Source: Internet
• At this point the impedance of the fluorescent tube falls to a minimum, and the voltage drop across it falls to a level below that required to ionise the gas in the starter contact gap. The contacts thus remain open until the lamp is next turned on. -Vitanza 1999 cited in detail - Source: Internet
• Many modern fluorescent light fixtures do not include starters, but most models older than fifteen years do. Check behind the bulbs for the starter, which looks like a grey metal cylinder attached to the frame of the light fixture. If you do not have a starter on your fixture, you can move on. A defective one can cause flickering or complete darkness. - Source: Internet
• If lamp tube is aging, it needs to be replaced with a new one. Large electromagnetic noise from the choke. It is mainly due to poor quality of the ballast and the large vibrations of the sheets of the iron core. Re-tighten the iron core of the choke if possible, otherwise replace it. Choke overheating Poor ventilation and heat dissipation. - Source: Internet
• Thus, the most reliable way to test a fluorescent bulb is to install it into a known working fixture. If you are troubleshooting a 4-tube fluorescent fixture, this is easy! Just remove one of the still-working pair of fluorescent tubes and replace it with each of the questionable tubes, one at a time. 99% of the time it will be one of the tubes that is the culprit. - Source: Internet
• are suitable for fittings in series. More common in older types of fluorescent light fittings. Electronic starters with a wattage range of 18 to 125 W, are a one-stop solution to all electronic ballast fittings. Their gentle start is designed to reduce wear and tear on the lamp. - Source: Internet
• Select the right starter for your fluorescent light fixture - see the FS- starter guide we give below in table form. Usually you will simply match the number of the old starter, or use an FS-U universal replacement starter. Press the starter down into the base, aligning its pins with the entry openings in the base, then Rotate it 45 degrees to click into place. - Source: Internet
• Check the starter. Check the ballast. Check the lamp you’ve used in the fitting is the correct size and fitting. If the issue persists, the tube needs to be replaced. - Source: Internet
• Check the ends of the tube. If they appear darkened this indicates the bulb is burned out. Rotate the tube in the fixture if the bulb is not darkened on either end. Remove the bulb from the fixture if the bulb is still not illuminating. - Source: Internet
• When power is applied to a tube light circuit, this voltage is not sufficient to ionize the gas inside the main tube. However, this power generates an electric potential across the contacts of small tube of starter. This electric field is large enough to ionize the gas inside the small tube and hence a current flow in the two contacts through the ionized gas. The heat generated due to the flow of current expands the bi-metallic plate towards the other plate and within a few tenths of seconds, it touches the other plate. This serves two functions – first, it will de-ionize the gas and second, it will increase the current through the filaments of the main tube. - Source: Internet
• However, if both tubes are functional, the problem is with the ballast or, if applicable, the starter. The starter is replaced first, and if that does not solve the problem, the ballast should be replaced. Read on… - Source: Internet
• Fluorescent lights are among the most popular lighting system used worldwide. Fluorescent tubes/lamps are filled with mercury vapor. They use electric charge to excite mercury atoms in order to produce ultra violet light. A glow starter or commonly known as starter is used in the tube light circuit to provide an initial current to filaments of the tube light. To understand the purpose exactly why a starter is used in the tube light circuit, let’s look into its circuit. - Source: Internet
• The first component to check is the starter. This is a small cylinder, approximately 2 inches long and usually silver colored. Its purpose is to accumulate current briefly when the light is switched on and then release it after the tube is lighted. - Source: Internet
• The small glass tube is filled with neon or argon and contains a bi-metallic plate. This bi-metallic plate is the heart of the starter. Among the two contact strips shown in the image, left one is attached with the bi-metallic strip as shown in the above image. - Source: Internet
• Fluorescent Starters Fluorescent starters or glow starters are used to help fluorescent tubes and lamps ignite in the initial starting stage of their operation. Simply put, fluorescent starters are a timed switch. The switch opens and closes until the fluorescent tube ‘strikes’ and lights-up. - Source: Internet
• When the switch is pressed current cannot pass through the tube initially because the gas inside it is not ionized and hence the tube light circuit behaves as open circuit. Once the gas is ionized, it will provide a conduction path for the current to flow. In order to ionize the gas, an initial high current is required for a short period across the filaments of the main tube. That is what a starter does. A starter initially provides a path to complete the circuit and once tube light starts the current flows through the ionized gas in the main tube. - Source: Internet
• When mains is applied to the circuit, the voltage is not sufficient to cause spontaneous ionisation of the gas in the main tube, and the lamp remains in a high impedance state (i.e. not turned on). - Source: Internet
• The starter (which is simply a timed switch) allows current to flow through the filaments at the ends of the tube. The current causes the starter’s contacts to heat up and open, thus interrupting the flow of current. The tube lights. Since the lighted fluorescent tube has a low resistance, the ballast now serves as a current limiter. - Source: Internet
• The ballast is a rectangular metal or plastic component resembling a small box with wires issuing from both ends. To test it, install a working fluorescent tube and a new starter. If the light malfunctions, the ballast is at fault and must be replaced. - Source: Internet
• When you turn on a fluorescent tube, the starter is a closed switch. The filaments at the ends of the tube are heated by electricity, and they create a cloud of electrons inside the tube. The fluorescent starter is a time-delay switch that opens after a second or two. When it opens, the voltage across the tube allows a stream of electrons to flow across the tube and ionize the mercury vapor. - Source: Internet
• The most common fluorescent starter is called a “glow tube starter” (or just starter) and contains a small gas (neon, etc.) filled tube and an optional radio frequency interference (RFI) suppression capacitor in a cylindrical aluminum can with a 2 pin base. While all starters are physically interchangeable, the wattage rating of the starter should be matched to the wattage rating of the fluorescent tubes for reliable operation and long life. - Source: Internet
• If replacing both the starter and the tube did not make the light work and the wiring was intact, then the problem is definitely in the ballast. If noise is the only problem, get a low-noise ballast, which is clearly marked as such. If the light is operated in temperatures below 50 degrees Fahrenehit - Source: Internet

• If this does not help, try wiggling the tube gently in its sockets by rocking it back and forth and from side to side. This will scour away minute deposits of corrosion or dust that can sometimes hinder the flow of electricity. Be sure to do this when the light switch is turned off. - Source: Internet

• A lighting starter slots in next to the fluorescent tube on the lamp frame. When the light switch is turned on, the starter sends a jolt of electricity to the gas inside the fluorescent tube, which provides the energy that makes the light fluoresce. If the lighting starter fails to work the fluorescent tube will not light up. - Source: Internet
• A fluorescent starter is a little gray metallic cylinder that plugs into a socket attached to the fixture’s frame. Its function is to send a delayed shot of high-voltage electricity to the gas within the fluorescent bulb. The delay allows the gas to become ionized so that it can conduct electricity. Because this process is not instantaneous, the bulbs will flicker for a few seconds before lighting. Hence, a defective starter can cause either flickering or total darkness! - Source: Internet
• Without the starter, a steady stream of electrons is never created between the two filaments, and the lamp flickers. Without the ballast, the arc is a short circuit between the filaments, and this short circuit contains a lot of current. The current either vaporizes the filaments or causes the bulb to explode. - Source: Internet
• I use the term “bulb” and “tube” somewhat haphazardly and inconsistently. My apologies. Both are correct, though “tube” is the more correct term and probably a little less confusing. - Source: Internet
• To purchase a ballast that’s compatible with your existing light fixture, you’ll need your lamp type, lamp quantity, and line voltage. You can typically find this information on the label attached to your ballast. It’s worth noting that T12 fluorescent tubes have been discontinued because of poor energy efficiency, so finding a replacement ballast for it may be a challenge. - Source: Internet
• High-quality starters significantly increase lamp lifespan, because by adjusting the starting current they reduce the lamp’s warm-up time. They improve lumen maintenance and reduce colour shift. The most popular application of lighting starter is in outdoor lighting, especially in large retail areas, parking lots, roads and tunnels, and in horticulture lighting. - Source: Internet
• A fluorescent starter can be tested by a multimeter very easily. For this, you need to turn the power off and then attach the multimeter at the one end of the starter. This will show the reading of the electric flow in the starter. If the flow shows normal, then you have a completely working starter. - Source: Internet
