Among all the lights under the cabinet (Xenon light, Incandescent light, and Fluorescent light) LED lights last longer.
When you know the average lifespan of LED lights, you wouldn’t hesitate to install it under cabinet lights and it will help you make better buying decisions as well.
How long does LED under cabinet lights last? The LED under cabinet can last for 25 — 30 years when it operates for 3 hours per day with 50,000 lifespan. When the LED lights are continuous in operation day after day without stopping, it will last for 15 — 25 years with 30,000 lifespan.
However, how long LEDs under cabinet lights last, depends on some factors. These factors are what determines the overall functionality of LED lights, especially under the cabinet.
So, let’s dive into these factors that affect the lifespan of LED light under cabinets.
The voltage at which your under cabinet lights uses is the determinant factor of how long it will last. The LED light could fail when it receives high voltage.
Evey LED lights are designed to work with specific voltage. When the LED lights are switched on either below or above manufacturer’s recommended voltage, the lifespan will decrease.
You need to know the exact voltage that’ll power your LED lights. The number of voltages that each LED lights are designed to function on is usually written on the body.
Let’s quickly define voltage, you can move to the next paragraph when you know the meaning of voltage.
Voltage is the amount of charged electrons that comes from an electrical circuit power source through a conducting loop, which produces brightness.
The easiest way to shorten the lifespan of LED lights is when it receives higher voltage.
If the amount of current that comes from the electrical circuit power is higher than the LED lights, it will automatically weaken the electrode inside the bulbs.
The recommended voltage in the U.S for LED light is 120 volts according to MIT Electrical Engineer grad, Luz Rivas.
This recommendation doesn’t apply to all LED lights under cabinets. There are some that use 12 or 14 volts. The best way to ensure you supply the LED lights with the right voltage is to check the voltage that’s being designed to function on.
For example, if LED light under a cabinet that’s designed to power under 120 voltages, and it plugs into a power source that produces 150 voltages, the lifespan will definitely decrease from what the manufacturer proposes.
Likewise, when the LED lights are using low voltage, the light will easily go dim. This will also make the LED lights not to last long.
Using appropriate voltage to power your LED lights under the cabinet will make it to last longer and shine brighter.
Voltage is a factor that determines how long your LED light under the cabinet will last. If you are not in constant supply of voltage, due to fluctuation of voltage, you can use an external voltage regulator to power your LED lights under the cabinet.
Single Switch Connection
Generally, the LED lights under the cabinet are high quality and easy to install. Most of the LED under cabinet lights uses less standard switch connection.
So, most people are not aware of these facts, therefore supply the same voltage they use at home to the LED lights under the cabinet.
Single switch connection is another factor that affects the lifespan of LED lights under cabinets.
Single switches built to control many LED lights that lack the capacity to supply the exact power will affect the lifespan. The higher the LED lights, the higher the power voltage required to power it.
Using a single switch could cause power surges, which can make the LED light not to last long. Single switch connection is good for LED lights that use the same standard electrical voltage at home.
Once the voltage under which your LED lights function is below the home, then single connection is not recommended.
Some people use it because it is easy to operate especially when the cabinet is in the kitchen or in an excluded area of the house or office.
But the danger is that power can easily surge and lead to the shortening of lifespan. One single switch is bad because when there is a power surge, it affects the entire LED lights connected to it.
Power surge simply means the spike in your home’s electrical current that mainly occurs when there is an interruption on the flow of currents.
There are two types of power surge:
- Internal power surge
- External power surge
Internal power surge occurs when there is an internal interruption of flow of electricity current.
Single switch connection can easily cause internal surge. It happens when the flow of electricity current experience delay — as a result of mal-function of the operator switch at the moment.
Once the operator switch doesn’t turn on the lights immediately it switches on, there is a possibility that a power surge has taken place.
To avoid power surge if you must use a single switch connection, use the exact socket voltage that has the capacity to power the number of LED lights you would connect to it.
Single switch voltage should be higher than the total number of LED lights voltage that’ll be connected to it.
If the LED lights voltages are higher than the single switch, then an electrical power surge will take place that’ll automatically affect how long it will last.
Another aspect that you can use to prevent your electrical power surge is by using standard line voltage dimmers.
The standard line dimmer will help you maintain steady flow of current. Because power surge occurs when there is no steady flow of current.
How long LEDs under cabinet lights last depends on the way it’s wired. Basically, there are two types of wiring that’s applicable to under cabinet lighting:
- Simple plug in
The LED lights under cabinet hard-wire involve taping lights directly from the existing wiring in the house. The electricity power is drawn directly from the power source.
Hard-wire allows the LED under cabinet lights to use the same voltages with the house. The issues associated with hard-wire systems is that the bulbs might not last long if the capacity is lower than the voltage coming from the house.
The hard-wire method requires the service of a professional electrician. Without the professional electrician, the issue of electrical surge might occur. Hard-wire that is drawn from the house must be of the same capacity with the wire used in the wall.
You need the service of a professional electrician to help you connect the under cabinet lights. Once the lights are well connected and the LED bulbs lights will definitely last long and bring out the quality brightness.
When you use the right materials to connect your lights through hard-wire methods, the LED lights will definitely last.
The simple plug in method involves the direct drawing of power from the source. This takes power from the power outlet, especially from the wall socket.
The use of plug-in lighting method is the simple way to connect your under cabinet lights.
It’s also a cost-effective way you can use to install the cabinet lights by yourself without having to employ the service of professional electrical that’ll cost you an extra bill.
The plug-in method is the simple way and more secure because the electricity wire in the house had already been done with professional electrical. Just plug-in to get your under cabinet light out.
For easy installation, we recommend you go for the plug in method to quickly get your under cabinet light on if your cabinet had already wired.
LED lights bulbs with dimmable features tend to last longer than those without it. Preferably, it better you get LED lights with dimmable features for your under cabinet.
The reason for the dimmable feature is that it helps to regulate the inner temperature and the lifespan as the bulbs shine.
Though using a dimmable feature bulb involves you incurring extra cost to get the dimmers. Then it helps to prolong the durability of the bulbs and give users the option to choose the type of brightness they deserve.
The dimmable feature helps you to save energy and give you control over the lighting. It helps to reduce the overheating from the bulbs.
Dimmer features for LED bulbs aren’t for long lifespan only, it also helps those with varying visual needs to make effective use of the bulbs.
For example a person with sight problems may want low-intensity lightning without the painful glare.
Dimmers ensure that everyone can work in the lighting conditions they prefer best. Dimmers also come in handy when you want some mood lighting in your kitchen.
Energy Efficiency LED Bulbs Light
Energy-efficiet LED bulbs lights are designed not to only be energy efficiency but to also last long. They are specially built with features that help the bulb light with a long lifespan.
So, if you want your under cabinet LED lights bulbs to last long, then go for energy efficient LED.
These sets of bulbs have a personal regulating system that makes the bulb walk perfectly well and to last longer than you may expect.
Fixture lenses are important in creating a uniform light distribution, minimizing bright reflections on the counter and reducing glare, which also help the bulbs to last longer than you may be expecting.
One of the major functions of LED lights is that it helps to regulate the amount of voltage that goes into the bulbs. It ensures the required voltage flow in power to avoid overheating or low voltage.
The LED lights with a nice warm glow, giving your cabinet a homely ambiance. They are also dimmable, which can help save some energy. The lense may light under the cabinet to last long and bring out more features.
The LED under cabinet lights last long when it is used properly and under the recommended voltages. The wiring also helps the bulbs to last more than what you may think or expect.
Using LED under cabinet lights will make it last longer. Some of the LED bulbs last up to 40 to 50 years under straight 3 hours used per day.
The operation of the lights require dimmable features for some while there are some that don’t require such features.
