Why are my led lights not bright?
Perceptibly shocking news, if your LED lights are not bright, while LED lighting is becoming increasingly popular to use in buildings and reputable over the globe ! LEDs are renowned because of good reason as they have brightness, long life, are highly energy efficient, can be dimmed and produce a low amount of heat and no UV rays.
LEDs have a good reputation all over, but there are some misconceptions surrounding LED lightnings that LEDs work the same up or to be run in original condition until the lights go out. Whereas in reality, though LED light suddenly dim and loses its brightness many times unknown to the building users. The reason has to be known is very essential to clear up the asking captioned above, “why are my LED lights not bright”, which we look into the reason by elaborating with this article.
Common Problems with LED Lighting For not Brighten Up
According to a survey report, 90% members who are using LEDs in their home are happy with their bulbs and the quality of lights. More than half have not experienced any problems using their LEDs. Other percentage ratios were experienced, 28% members faced failures, 12% members faced flickering, 5% members faced buzzing and radio interference 2% were the main problems encountered.
Although, there is common for the people to ask why the LED light suddenly dim. This problem might be happening for both endorse and outdoor LED bulbs. This is usual LED bulbs can lose their brightness due to so many reasons. Let us discuss and explore the reasons behind.
One of the main causes is the loss of brightness due to improper power supply for LED lights, resulting in the LED lights suddenly dim. While LEDs can not reach the maximum brightness, if the rated voltage or current is not fixed up. When you buy the LED lights from a manufacturer or any marketplace, you need to know about power, voltage and current input accurately LEDs required for using your own driver. If the power rating of the driver does not match with the LEDs, the flood light bulbs will not be bright or sometimes can burn out. So it is suggested to adopt the original setting of whole LED lights.
The building owners or LED lights users suffer due to loose connection of wiring and even face a dangerous situation. In fact, if the wires are not firmly connected resulting in some of the LED chips inside the light will not be on, and thus reduces the overall lumen output, so that bright LED light bulbs may flicker.
Using long period of time
Due to aging LED light suddenly dim and it can reduce overall brightness. If the LEDs used for a long period of time are not bright enough because electronics inside the lamps start to deteriorate thus they no longer produce the 100% lumens. Actually, if a LED light is rated as 80,000 hours at L70, the lumen output will fall to 70% of the original value after 80K hours. In recent days, most LEDs have a long lifespan of average 50,000 to 100,000 hours equivalent to 20 to 30 years depending on how long you continue switching on the bulbs.
High Ambient temperature
If the ambient temperature is high the LED lamps are not to be bright. As per scientific research, LED produces the maximum brightness at around 25 degree Celsius junction temperature. Whereas the working environment is very hot like 40 to 60 degree Celsius, the lumen output of white light drops to approximately 65 to 80 percent of its maximum value. Unlike the usual bright LED lights can be more brighter in the cold weather than its original value, because it is suitable for them. Special reinforcement on LED luminaries is required if the ambient temperature can be over 80 degree Celsius like foundry, nuclear power station and for industrial application.
Why are my LED Lights Dim and suddenly brightens?
Sometimes the householders become astonished for unexpected things in LED fixtures and one the miracle they often face as while switching on the LED light suddenly dim for a moment and then return back to brightness. Thus the users are yet to realize and make an issue as problem LED lights dim then brighten.
High Load Appliances
In order to lead a family life, it’s usual that other appliances are needed, which are high loaded like washing machines, dryers, or microwaves in the same circuit as your bulb with, and your appliances are switched on. Obviously you will experience that surge wattage. While your LED lights suddenly dim in a single room or phase, this is where surge wattage comes into play.
In fact, all the appliances draw a high surge when power to Turn On, then continue running. Therefore the sudden change in voltage affects the light bulb output, which then automatically corrects itself within a moment.
Disputed Electrical Panel
The other cause might be happening throughout the user’s house or offices that bright LED lights are dimming all the time. Actually this is a less frequent but more serious cause for the premises or areas dimming could be a loose or corroded neutral wire in the electrical panel. In order to prevent any unforeseen situation like fatal house fires due to arching and a short circuit, immediately it’s essential to get loose wiring fixed.
Nowadays natural calamities are a phenomenon all over and a big storm may happen anytime you never know. In case your house lights dim then brighten returns for a moment, immediately take initiative to check the surrounding area or your neighbours, whether the same things happened with them. Then without taking any delay, check your service cable running from your electrical panel to the meter and further on, if it happens again the transformer may be at fault.
Any times with any cause like emergency, cyclone, or earthquake your town area or city may have a blackout, that is complete power failure. In that situation, you can call your city power distribution company and they will remedy the loose or disconnected wiring, that way you can resolve the problem of LED light suddenly dim or not turning on.
Why is the new LED bulb not bright?
It is well known LED bulbs are energy efficient and have a long lifespan of more than a decade. Increasingly people are more interested to switch over, as the technology has improved to allow for brighter bulbs that look almost identical to traditional light bulbs. Therefore, bright LED lights work differently to old style light bulbs, so this can cause some issues when fitting them into older circuits. Brightness of LED light bulbs depend on the following reason:
Lumen Rating: Higher Lumen rating is firmly required LED bulbs for brightness. Lumens measure the brightness in LED lighting which is different than Watts and measure the amount of energy in a light. Lumens means “Light” which measures the amount of light LED light puts out. Bright LED light to be focused more brighter if higher lumens are supplied.
In fact, measuring the brightness of light is more important than measuring its power, that is how much power inputs to the light. The traditional incandescent light bulbs were measured in Watts, which showed how much power used. Higher wattage creates brighter light for incandescent bulbs. In advanced technology brightness LEDs light bulbs depend and measure on lumens.
Incompatible Dimmer: Most householders bought the LEDs and used the existing fixture and connected to the old dimmer switch, then incompatibility might be at play. LEDs need to be dimmable, and also dimmer needs to be compatible with dimmable LED. If you find a new LED bulb is stuck at low brightness with a dimmer, you should understand a component with the dimmer has likely died due to the nature of LED dimming high frequency on/off cycles. Compatibility is an essential factor while LED bulbs still work with incandescent dimmers. So your bulb might be okay but need to choose a universal or compatible dimmer switch.
Older wiring: It makes sense, older houses may have older wiring that are getting poor and no longer able to consume the load of high powered and numerous electronics around the house. It is usual that maximum current running through old wiring to a home or office can lead to low overall voltage and brand new bulbs might end up being dim.
Why does the LED bulb dim over time?
Since LEDs are reputable for various reasons including long lifespan, but a question that is commonly asked is, Do LED lights dim over time? In fact, there is really no short answer to this question. It’s known to all that LED lights are quite durable and last a very long time than the other traditional bulbs, even they can last for decades with normal use. Naturally LED lights will gradually dim, unlike other bulbs that blow or burn out all at once. But good news is LED will take quite a long time for this to occur.
If the capacitor is at least one swollen or bulged on the circuit board of the LED, the other capacitors will be intact, and thus current will be running through only remaining working capacitors. It reduces the voltage being supplied to the emitters and thus dimming the light visibly. LEDs can prematurely and rapidly reduce lifespan if a tight and non ventilated fixture is used that can trap heat. Usually LEDs typically operate most efficiently in temperature ranges 40 to 60 degree Celsius and in freezing weather it runs well.
Finally External and internal power supply may be the cause of dimming bulbs as flood lights are external power supply to the LED, therefore you have know about current, voltage and power ratings. Power factors depend on the driver’s efficiency and while power supply rating does not match that of the LED will result in dim light output.
While popularity is surprisingly and rapidly increasing more and more occupied in the highest position day by day considering with many of the qualities and advantages of Light Emitting Diodes (LED), then queries, curiosities and questions to be arise more and more not stopping unless having perfect knowledge of the products.
However, today’s technology is used extensively for commercial, industrial and residential application. As such LEDs capabilities have been increased across the board, increases in lifespan, increases in brightness and increases in energy efficiency. Resulting greatly expanded use of LED technology has led to the development of warranties, industry best practices and the introduction of government programs as well as many other sectors.
Finally, We would like to conclude with a thoughtful memo that a positive symbol of intellect is when asked questions for the whole thing and are always unsure about the item and dope are forever so damn sure of everything.
