Common Problems with LED Lighting

LEDs are undoubtedly a fantastic modern-day replacement of tube lights and incandescent bulbs. LED lights are both energy efficient and brighter than their predecessors. Also, you can expect a longer life span from LED lights. But there are some downsides to LED lights as well.

Flickering light, humming sound being some common problems of LED Lighting. If you want to know what more problems can LED lights cause, then read along.

1. LED Light Flickering

LED Light Flickering

One of the most common and frequent problems with LEDs is flickering. In this case, the LED bulbs flickers, sometimes continuously, while sometimes, it happens randomly. The most common reasons behind this are poor capacitors or low wattage.

Sometimes, LEDs are connected with devices like washing machines, dryers, etc., which take up maximum wattage. And this leaves the LED with inadequate wattage leading to flickering. To fix this issue, you need to check the socket. If the socket is okay, you can replace the bulb or vice versa.

2. LED Buzzing or Humming Noise

LED Buzzing

Buzzing sound is another common issue with the LED Lighting. It’s usually because of overload in the circuit. If your LED bulb is receiving slightly higher voltage, it’ll produce a humming sound instead of blowing off. When the voltage rises, the electronic parts vibrate, causing the fuming sound.

The best solution is to compare the voltage that runs through your socket with what your bulb or lamp accepts. It’ll most probably solve the problem.

3. Too Bright light

TOO BRIGHT LIGHTSometimes LEDs become too bright for your liking. And it can be due to two reasons. The first one is that that the bulb is getting more wattage than required. Secondly, it can happen because you might have got a Kelvin temperature bulb, which can sometimes be too bright.

If your bulb is dimmable, install a switch to control this feature. Or use a fixture that can prevent extra light from reaching your eyes.

4. LED Light Too Dim


A dim LED can be quite irritating. It usually happens either when the LED gets too old or when it’s poorly designed. LEDs have a life span, so before dying out completely, it’s normal to lose brightness. In such a case, you should replace the LED with a new one.

5. LED Light Stopped Working

LED Light Stopped Working

Sometimes the LEDs stop working altogether. This usually happens because of a short circuit or when the LED has become too old. You can get it checked by an electrician or simply replace it with a new one.

6. LED Flashes on and then Goes off

It happens due to faulty fixture drivers. Sometimes, the voltage supplied to the LED is more than what it requires. And this makes the LED flash and then go off. If you face this issue, it’s better to call a technician.

7. LED Dimming Does not work

LED Dimming Does not work

There can be several reasons behind this happening. Your bulb may not be dimmable. Or the fixture isn’t meant for dimmable LED bulbs. You can get it checked by an electrician and diagnose the problem. You can buy a new bulb if it wasn’t dimmable or can replace the fixture.

8. LED Strip Showing the Wrong Color

RGB LED strips are meant to show different colors. But if you notice the wrong colors, it’s a problem. It happens as there might be a wrong wire connection. Or there is a fault in the LED controller. However, you can check the wiring and replace it if there’s no fault in the wires.

9. Recessed LED Light Turns Off after a few Seconds

When too much heat builds up, the LED can shut down. It happens when you install LEDs in the recessed light nooks, which are not well spaced for LEDs. In such cases, you can install a new holder socket for your LED.

10. Random Turn Off LED Recessed Light

A recessed fixture is not well designed to allow the free movement of air. And if you install an LED in the place, this problem can occur. It’s because LED needs air to keep itself cool. When that doesn’t happen, it heats up and turns off.

11. LED Light Attracts Bugs

LED Light Attracts Bugs

Insects/Bugs are only attracted to certain kinds of wavelengths. But it can happen with LEDs if the Kelvin favors them. Anything above or below this range 2000K-5500K can attract insects. So, make sure that you buy LEDs lying in the above range.

12. LED Light Overheating

It happens when you install LEDs in old fixtures meant for recessed lights. Such fixtures are congested and don’t allow air to pass, which can cause this issue. You can upgrade to IC-rated recessed Lighting. It offers better air circulation, which will prevent overheating of LEDs.


Poor quality LEDs with no warranty usually cause this issue. And the solution is simple, and you can replace the LED with a branded one from a reputable brand with a warranty.

14. Wrong LED Beam Angle

Different LEDs are meant for different purposes and come with a Beam Angle. If you want to use LEDs as a floodlight and face the wrong Beam Angle, you might have bought the wrong type of LEDs. In this case, replacing is the best decision.

15. Blue Light Pollution of LED

LEDs with higher Kelvin levels are brighter and have higher levels of blue light. You should choose a light with a warmer spectrum or has a lower rating on the Kelvin chart in such cases. It will have less blue light, which won’t disturb your eyes.

16. Using LED Light in an Incandescent Light Fixture

Most of the time, LEDs function well in incandescent light fixtures. But due to limited air supply, the LEDs can heat up and turn off. Also, the dimming feature might not function when an LED is installed in an incompatible fixture. In such cases, you should replace the fixture with a compatible one.

17. Using LED Light at an Extra High Current/Wattage

Incandescent lights become more or less bright with wattage. But this doesn’t happen with LEDs. In an LED, what matters is the Lumen. So, when you’re buying an LED with the same wattage as the fixture, it might not work. So, convert the wattage into lumens and choose the one with the right lumen rating.

18. Low Color Rendering Index

80 CRI & 90+ CRIIf the CRI is lower, whatever you see in the Lighting will be less bright or less clear. It is similar to photography. Although 80 CRI is good, you can buy a LED with a 90+ CRI rating for brighter and more saturated light.

19. Wrong LED Driver

Every LED light comes with drivers, which is responsible for supplying the power and run successfully. However, if the LED is incompatible with the driver, you can face problems like the LED turning off due to overheating, burning of LED Driver. In such cases, you should compare the drivers and buy a compatible one.

20. Corn Bulb Protrudes Out of the Lampshade

CORN BULB PROTRUDES OUT OF THE LAMPSHADECorn bulbs come in different shapes and sizes. Sometimes, they are too long or large to fit in the fixtures, which can cause them to protrude out. This can reduce the lifespan and can also make it look absurd. So, buy a bulb that’s compatible with your lamp.


Here ends our list of common LED-related issues that you might encounter. We have tried to cover almost every issue out there. The best solution is to contact the retailer or a technician if you face some other problem.

However, if you want to avoid the above problems, you should choose a branded LED with the correct wattage, size, and drivers. This will ensure longer and problem-free usage.
