Lights burn out8/4/2023 ![]() ![]() If your light bulb is not receiving proper ventilation by being covered in a recessed fixture (dust building up in the wiring or on the bulb can worsen this), it is easy for it to overheat. If your believe this can be your issue, try using either the correct size light bulb for that fixture or a lower watt light bulb instead. If you are using a light in a fixture that it is too big for or a fixture which is enclosed has the wrong light bulb being used, heat is usually the problem.Īlthough you may be able to screw a large light bulb in a fixture, the fixture will not be capable of dispersing heat adequately if it is designed for smaller bulbs. Too much heat: Bulbs can burn out from becoming excessively hot, even when using the correct wattage. ![]() ![]() A short circuit can be caused by a whole lot of other problems that we won’t go over here, but to identify that as the problem simply check if other light fixtures and appliances are also affected. Something like a ceiling fan or a continuous repair work upstairs can easily cause this problem.Ī short circuit: In this case, it’s not the bulb that’s burnt out but your home’s wiring. Too much fixture vibration: This may sound too implausible but it’s actually a common problem – if there are too many or too strong vibrations around the lighting fixture, these can cause the filaments inside the bulb to jiggle and shorten its life. This can cause it to damage the circuitry at the bottom of the bulb over time and cause it to burn out too quickly. Wrong dimmer switch: If you have an older model dimmer switch it’s possible that it’s designed to work with standard incandescent bulbs only and isn’t suitable for CFL or LED light bulbs. To fix this, just turn off the power and check the bulb socket – the wires need to be securely and firmly attached to the screw terminals. If it’s a little lose it may flicker on and off which will cause it to expire quicker, not to mention that it’s just not good for lighting. Loose connection :Another thing to check for is whether the bulb is connected to the fixture properly. To avoid this simply look at the voltage the light bulb is supposed to work with and use a multimeter or a voltage tester to check the socket’s voltage. Too high voltage: If the supply of voltage coming into the bulb is too high for it to handle, you can very much expect it to burn brighter and faster than expected. So, without wasting any more time, here are the main reasons why your light bulbs might be burning out quicker than expected. You can choose to replace them once they have dipped to a level that is no longer enough for your needs. So LEDs won’t suddenly break and stop emitting light – they will eventually just not be bright enough to be useful any more. Depending on the amount of ventilation around the bulb, this can eventually cause them to fail. The electronic components (such as chips and capacitors) inside LED bulbs can struggle under these temperatures. Because this is such a small space, the heat builds to a pretty high temperature and raises the temperature of the air trapped inside the bulb. This waste heat collects in the neck of the bulb above the socket. However, they are still not 100% efficient in turning electrons into light some of the power still comes out as heat. LEDs are far more efficient than older types of light bulb. Instead of burning out suddenly like traditional bulbs, LEDs get gradually dimmer, as the individual light emitting diodes that make up the bulb fail one by one. LED bulbs have no filament and work in a completely different way, meaning they don’t reach such high temperatures. Even being turned on and off damages normal bulbs, but not LEDs. These filaments are very delicate and eventually break or burn out. These bulbs work because of a filament that heats up enough to glow, giving off light. The incandescents that LED bulbs are generally replacing these days give off 90% of their energy as heat, rather than light. ![]()
