Why is LED bulb flashing?

Everyone who has an LED bulb will agree that they are perfect for houses and offices. LEDs have many advantages – most of all, they are definitely more energy-efficient than incandescent bulbs. Unfortunately, there is one common issue with this kind of lighting – flashing and flickering. This is not a problem with a LED light bulb that keeps burning out. However, it can be a bit annoying and distracting for users. Why is the LED bulb flashing? How to fix it? Is it possible to avoid this problem?

What are LED bulbs?

Technically, a LED bulb isn’t a bulb. Its name comes from “light-emitting-diode”. It basically means that these bulbs are semiconductors. They are not very big. They are wrapped in plastic so that all the elements were protected and the light was focused. Instead of a filament, there are two electrodes, which allow electricity to pass through. Electricity is transformed into energy thanks to semiconductors.

LED lighting is very impressive. Many people choose LED capsules and even LED candles instead of incandescent bulbs. This is not surprising – LEDs consume up to 90% less energy than traditional lights. They are available not only in daylight but also in warm white and cool white. They also have dimmable options. They transform the feel and the look of any environment.

What is causing the flicker?

LED bulbs may flicker or flash for many reasons. Disruption in the consistent light stream might be problematic. Flickering and dimming usually happen when there are voltage fluctuations in the house’s waring. Sometimes, electrical loads turn on and turn off in your home. It happens to anyone from time to time. This situation is the reason for a change in voltage levels. It may cause LEDs to occasionally flicker or dim.

Too many appliances in use at the same time

There are some appliances in your home, which need much more power the first time you turn them on. The result is energy expenditure – voltage drop. Another reason why LED light bulbs are sometimes flashing is that there are too many appliances or electrical systems in use at the same time.

Incorrectly selected dimmers

Flashing in LED bulbs may be caused by incorrectly selected dimmers. LEDs simply cannot operate with inappropriate dimmers. In other words, the dimmers which are good for traditional light bulbs and halogen bulbs won’t always be appropriate for LEDs. 

Loose wiring or loose bulb

There are also high watt surges when the electrical system or a device is turned on. Another issue is a loose connection between the bulb and fixture. A loose connection between wiring within the fixture is another problem.

How to fix flashing LED light bulbs?

As you already know, there is nothing wrong with LEDs. You don’t have to get rid of them. The bulbs don’t necessarily mean to be replaced. Simple troubleshooting is enough to solve the troublesome flashing. It can also help you in restoring function and, what is more, it will help you in saving the cost of replacement.

Check your electrical current

You definitely don’t want your LED bulbs to flash, that is why you ought to check your electrical current. Thanks to it, you will avoid voltage changes in the fixture’s wiring which leads to currency fluctuations.

Voltage fluctuation is also likely to blame when LED lights start to flash and flicker in the case of using many appliances at the same time. The only thing you have to do is to solve fluctuating load issues connected with your electrical system.

Install the proper dimmer

If your LED light bulbs are flashing, you should install the proper dimmer, which is compatible with the circuit. You’d better use only dimmable LED bulbs in a light circuit. The dimmer switch should be removed and replaced with a conventional light switch. You should also replace LED light bulbs that are non-dimmable with these light bulbs that are capable of dimming.

Search for high watt surges

Surge wattage may be another reason for LED bulbs flashing. That is why you ought to look for high watt surges. One appliance which turns on and draws power is enough to drain the power required by the LEDs. It’s a straightforward way to drop the home’s voltage. What should you do in this situation? The best solution is to move problematic devices to a dedicated circuit. Second-Hand Exercise Bikes for sale Life Fitness, Precor, Matrix 2023

Use compressed air

If you tighten your bulbs and it doesn’t resolve to flash, there is only one explanation for this kind of situation – debris and/or dust within the fixture connections. It may be the cause of the loose connection leading to flashing and flickering. You ought to use compressed air in order to blow out the fixture’s connection point. You could also reposition the bulb. Don’t forget to restore power when you’re finished. 

Why only the best quality LED light bulbs are worth buying?

Well, the truth is that low-quality LEDs may also contribute to flashing and flickering. When fixtures are built with poor connections, flashing may become a permanent problem. In this case, replacing your LED bulbs would be the only option. You probably don’t want that, that’s why you should bet on the best quality lights. You can find them here: If you are looking for a wide range of LEDs with fast and free delivery – you will be pleased.


Flashing and flickering may be problematic when it comes to LED light bulbs. However, it’s not a problem without an answer. As a user, you should check your electrical current, install the proper dimmer, look for high watt surges and use compressed air in order to have clean connections. Don’t forget that the quality of LEDs also matters! Choose the best quality lighting available on the market and enjoy it without any flashing.

How to choose the best-led bulbs?

Choosing a LED bulb above all has a reason for energy efficiency and, therefore, consumption. Several aspects must be taken into account when buying an LED bulb:

  • The type of bulb and its measurements.
  • Let them be adjustable.
  • The hours of duration in complete conditions and its useful life.
  • The brand: there are many firms, but some are better than others. It is advisable to always bet on the best-known brands.
  • The consumption in watts if what we want is to save energy and money.
  • The color of the light emitted by the bulb will depend on where we want to put it: at home, in a business, in an office

What are led bulbs?

They are light-emitting diodes (LED) and are semiconductors. When electrons pass through this type of semiconductor, they turn into light. Compared to incandescent bulbs, LED lights are more efficient at converting energy into light and consume less electricity.

What are they for, and how do they work?

An LED is a small light bulb that fits easily into an electrical circuit. These bulbs do not heat up and are illuminated by the constant movements of electrons in the semiconductor material. The average life of an LED is approximately 20,000 to 50,000 hours and exceeds the life of typical incandescent bulbs by several thousand hours.

The average life of an LED is approximately 20,000 to 50,000 hours and exceeds the life of typical incandescent bulbs.

Today you can find LED lights in various applications, including LCD televisions, in the home, offices, stores, etc. They are usually installed in places where there must be artificial light for many hours. The objective is to save electricity consumption and that, in addition, they have a long useful life.

types of led bulbs

There are several types of led bulbs:

  • Standard: for ceiling lights, wall lights, and hanging lamps.
  • Spherical: for ceiling, table, and wall lights.
  • Globe: for desktops and on walls and lampposts.
  • Candle: for hanging lamps, wall lamps, and table lamps.
  • GU10 and MR16: ideal for recessed spotlights, bathrooms, and kitchens.

Depending on the type of lighting, there are the following models:

  • Warm light (3,000K): cozy light for bedrooms, living rooms, or dining rooms. ​
  • Natural light (4,000K): they provide a more excellent sensation of light, and their recommended use is for kitchens and bathrooms.
  • Cold light (6,000K): garages, offices, and workshops are usually the most suitable places.

What do led bulbs contain?

LED bulbs are made up of the following:

  • An anode (positive).
  • A cathode (negative).
  • The lens (a normally epoxy plastic encapsulation).
  • A metallic contact that performs the function of a conducting wire.
  • A reflective cavity (also called a cup).
  • an anvil
  • A platelet.

Why do they burn?

Burning out of a light bulb can happen for several reasons:

  • That its useful lifetime has reached an end.
  • The switches are faulty, which implies that they can cut the current instantly and generate parasitic currents that increase the circulating voltage.
  • Your electrical installation has current peaks and exceeds the working voltage of the lamps.
  • The excess temperature in the lamp.

How to prevent light bulbs from burning out?

It is not normal for a light bulb to burn out. Even so, the main recommendations are:

  • You should bet on quality bulbs: some manufacturers offer a lot of light but lower costs in materials that, in the long run, will cause problems.
  • The heatsink and the driver are the heart of the LED bulb: the better quality they are, the longer the bulb will last.
  • The bulbs need to be cooled; if they don’t, they will lose their properties
  • In installing LED bulbs, you should not mix them with other types of lamps, such as fluorescent or halogen: they can cause problems.
  • It is not necessary to install LED bulbs in completely closed ceiling lights or downlights.
  • Check the installation: if many bulbs fail simultaneously, likely, the problem is not with the bulbs.

Do they cause any damage?

Depending on the color and wavelength, LED bulbs are made up of different components, and some of these must be treated appropriately when recycling them. Care must be taken in this process because they have a particular risk of harm to the environment and people’s health. The same happens in any other type of light bulb. Still, LED bulbs have far fewer health risks than different types of bulbs.

The most powerful flashlights on the market


Experts always recommend being in natural light as much as possible. They ensure that excessive exposure to LED-type rays at night, which include a peak of blue light in their emission spectrum, could be related to harmful effects on health. The reason is the production of melatonin, a hormone that we begin to produce naturally in the afternoon and reaches its maximum at night in dark conditions.

How many amps does a lead consume?

The LED has an operating voltage that goes from 1.5 V to 2.2 volts, approximately. The range of current that must flow through it is between 10 and 20 milliamps (mA) for the red diodes and between 20 and 40 milliamps (mA) for the other LEDs.

Cold or warm light?

The first thing to know is each type of light:

  • Neutral light: it is similar to the light we have at noon.
  • Warm light: it is more reddish or orange, similar to that of a candle.
  • Cold light has bluish tones and LED bulbs are the most advisable if we want to achieve this light in a more ecological way.

Choosing one type of light in the home is more a matter of taste and a sense of aesthetics, depending on whether we want to create one kind of environment. It is recommended to apply the lights according to the place of the house:

  • Kitchen: cold morning.
  • Dining room: Neutral morning – cold.
  • Bathroom: Neutral light.
  • Living room: Warm

The most problematic type of light for our health is blue, and this is the one emitted by most lamps and LED bulbs. Can produce:

  • Sleeping problems.
  • Poor brain recovery.
  • Poor muscle recovery.
  • Metabolic problems.

Does the color of light from bulbs affect sleep?

Sleeping with light is not good because the body does not rest as if it were resting with the light off. Even so, there are lights that are less harmful to our sleep. The light that can hinder our rest the most is blue light due to its cold, bright, and intense tones. First, avoid using this type of light in bedrooms and resting places.

What lights are recommended to put in the bedroom?

The most recommended type of light in restrooms and bedrooms is a soft and warm light that invites rest and provides tranquility. In addition, it must be a uniform light such as those offered by warm energy-saving light bulbs. A piece of advice is to use direct lamps focused on the ceiling or with lights attached to the wall.

What are the best-led bulbs on the market?

There are many types of LEDs on the market, and they all have similar properties. The recommendation is always to go to recognized brands that have been manufacturing them for years. When buying them, look at their consumption and the valuable life hours. Among the most outstanding models are those of Philips, Osram, Albrillo, Bomcosy, LVWIT, or Locked.

LED Lighting Pros and Cons

It would help if you chose from many different bulb types when deciding on the right light fixtures for your home. LED light bulbs are one option; like other choices, they have unique advantages. There are also disadvantages to LED lighting. When weighing the benefits of LED lighting, you’ll need to consider several factors. Consider these LED light bulb comparison factors and learn about LED lighting. That way, you won’t be in the dark when deciding.

What is LED Lighting?

LED stands for light-emitting diode. When voltage is applied to the two leads, electrons move around and create light (electro-luminescence). By comparison, an incandescent bulb lights up when the internal filament is heated; a CFL bulb glows when an electrical current runs through the gases in the tube. There are numerous LED lighting fixtures so you can find plenty of styles for every room in your home. Many options are stylish and energy efficient, from pendant lights for the kitchen to LED outdoor wall lights for a deck.

Pros of LED Bulbs; LED Advantages

There are numerous LED advantages to consider when you install LED bulbs. First, they last up to 50,000 hours. It is a significantly longer lifespan than both incandescent lights and CFL bulbs. These long-lasting LED lights significantly reduce the need to purchase and install replacements: this makes LED recessed lights and LED chandeliers, or pendant lights, a brilliant choice to install in those hard-to-reach places — such as from high ceilings and stairwells. LEDs are also energy efficient, using about six times less energy than incandescent bulbs. It means that LED lights will provide you with significant savings on your electric bill. Some local and state governments even offer rebates or other incentives to switch to LED bulbs.

Other Benefits of LED Lighting

LEDs are often compared to their energy-efficient cousins: CFL bulbs. LEDs, unlike CFLs, don’t contain mercury. If an LED light breaks, you don’t have to be concerned about a complex (or dangerous) cleanup process. Fixtures with LED bulbs also don’t require any “warm up” time after being switched on; this eliminates the time needed to reach full brightness. Several types of LED light bulbs emit different colors so that you can add some fun effects to your home’s lighting.

Disadvantages of LED Bulbs

One disadvantage of LEDs is the high initial cost per bulb. Over time, however, LED lights will pay for themselves through energy savings and incredibly long lifespans. Bulbs from various manufacturers may appear noticeably different in their white light hues, so choose a well-known brand. 

Most white LED bulbs emit a cooler, blue-tinted light — rather than the “warmer” glow associated with incandescent bulbs. Some people prefer “daylight” or “natural light” LED options. Some LED fixtures may create sharp shadows that may not be desirable in certain places in the home. Other disadvantages of LEDs are that not all LED bulbs are dimmable; those may require special dimmer switches. 

If dimmable LED fixtures are essential to you, it’s wise to check the bulb’s packaging carefully if you want adjustable lighting. Finally, some standard LED bulbs, such as flush mount lighting, may not be compatible with your existing enclosed fixtures. However, some manufacturers offer specialized bulbs for enclosures.

Are LED Fixtures Right for Your Home?

Depending on their use and convenience, certain areas of your home may benefit more from LED lighting than others. Areas where changing bulbs is often tricky, such as high ceiling lights, are good candidates for LED lights. Areas where the quality of the light (tint) isn’t as important, such as outdoor areas, may also benefit from LED fixtures. When looking into LEDs, you should consider certain performance aspects, including lumens and color rendering index (CRI). 

The number of lumens refers to the amount of light output (brightness); CRI describes the quality of light compared to a familiar reference (such as daylight). The best-LED light bulbs have a high lumen count and CRI of at least 90. Once you’ve installed your new LED fixtures, you can enjoy energy-efficient lighting with almost no required maintenance.
