LED lights (or Light Emitting Diodes) are the new standard in home lighting and a great option if you\u2019re looking to update your interior decor.<\/p>\n\n\n\n
They\u2019re faster, more robust, brighter, and more customizable than traditional incandescent or halogen lights. Even if they\u2019re a little more expensive initially, LEDs will save you plenty of money in the long term!<\/p>\n\n\n\n
To simplify things greatly: LED lights create light using a material called a semiconductor. <\/p>\n\n\n\n
When electricity is applied to this semiconductor, it creates an electromagnetic field. Within this field, electrons flow and collide with other atoms. This releases energy in the form of photons \u2013 thus producing light.<\/p>\n\n\n\n
If you\u2019re looking to install LED lights in your home, you may be wondering: Do they need a ground wire?<\/p>\n\n\n\n
In this article, we\u2019ll break down this question and more. Specifically, we\u2019ll cover:<\/p>\n\n\n\n
Let\u2019s get started!<\/p>\n\n\n\n
Technically, no. A ground wire often isn\u2019t required for LED lights to work properly. However<\/em>, you should have one anyway! Ground wires make LED lights (and electronics in general) much safer, and can prevent them from being damaged by surges.<\/strong><\/p>\n\n\n\n Also, in rare cases, lack of a ground wire can cause certain LED lights to be dim, flickery, or not work at all. You can likely find this information on the manufacturer’s website.<\/p>\n\n\n\n Your electricity should be grounded wherever possible. This helps prevent damage to your devices, electrocution, and fires. For the sake of a small convenience, skipping ground wires just isn\u2019t worth the risk.<\/p>\n\n\n\n Throughout your life, you may have noticed that some power outlets have three holes while others have two. Similarly, some plugs have three prongs, while others have only two.<\/p>\n\n\n\n The two prongs that sit side by side are the \u201cmain\u201d power conductors of the plug, while the optional third prong is the ground connection.<\/p>\n\n\n\n Grounding is used with AC wiring as a safety feature, protecting both you and your devices.<\/p>\n\n\n\n If a power surge occurs \u2013 usually because of a storm or other environmental effects \u2013 the ground connection will redirect that burst of electricity into the earth. There, it can be safely discharged.<\/p>\n\n\n\n Without a ground connection, this surge of electricity will instead go straight to the device connected to your power grid. There, it could cause the device to break or \u201cblow\u201d, or it could make the surface of the device electrified.<\/p>\n\n\n\n As you might imagine, touching a device that\u2019s been electrified like this is unpleasant. In some cases, it can be fatal!<\/p>\n\n\n\n The National Electric Code made grounded outlets mandatory in all new builds in 2011. So, if your home was built in or after 2011, it should have ground wires installed. <\/p>\n\n\n\n If your home doesn\u2019t have ground wires, it\u2019s worth getting them installed for increased safety.<\/p>\n\n\n\n Most LED lights will work fine without a ground wire. <\/p>\n\n\n\n In some cases, you might notice ungrounded LED lights making a buzzing sound since they rely on their ground connection to dissipate electrical noise. They\u2019ll also be more susceptible to damage from surges. <\/p>\n\n\n\n A ground wire doesn\u2019t just protect you from excess electricity \u2013 it also protects your light. If there\u2019s a surge and your light doesn\u2019t have a ground wire, it\u2019s likely to be blown out and need replacing.<\/p>\n\n\n\nUnderstanding the Ground Wire for Power Supplies and LED Lights<\/h2>\n\n\n\n
