Why does my LED light blink?

The first reason is of course that your bulb may be defective. In order to check if this trouble comes from the bulb, we advise you to replace the blinking bulb with a bulb working properly. Be careful of course to cut off the power during the exchange of the bulbs. If the second bulb is also flickering, the problem comes from the electrical circuit or the socket. Conversely, if the second bulb works properly you will certainly replace this bulb.

Depending on the geographical location and the time of day, it may happen that some LED bulbs start to flicker, to make a kind of slight tremor in the lighting that disappears after a few moments. What is the origin of this slight flicker?

What is the influence of this change of tension?

An LED bulb operates in a very specific voltage and intensity range. When one deviates from this range, the operation is no longer optimal. To regulate these parameters, a bulb is equipped with an electronic circuit with a component that ensures a stable voltage and intensity. However, when the input voltage is outside the range 220/240 Volts, these components can no longer ensure the voltage and the ideal intensity which is intended to cause a blinking of the bulb. Some LED bulbs are limited to 220 / 240V, others have wider entry ranges i.e. 175 / 265V these bulbs are much less prone to flicker.


Does this phenomenon degrades the life of the LED?

No, this flicker is not harmful to the life of your LED lamp. It only reflects an output of the input voltage of the 220/240 Volt range at which the bulb via its electronic circuit must fit.
Does this phenomenon occur with other light sources? Yes, flickering also occurs with halogen bulbs, incandescent or compact fluorescent but is generally imperceptible to the human eye.

How to prevent this flicker?

If you live in a region that is highly subject to voltage deviation, you can install MR16 12Volt bulbs which, unlike a conventional E27 bulb, have the input voltage and are regulated by a 12V DC power supply. This installation change will solve the whole problem. You can also opt for light bulbs 175 / 265V, for example, this bulb E27 12W better quality.

The color rendering index (CRI or IRC)

The color rendering index (CRI or IRC) The color rendering index (CRI) is a fairly simple concept characterizing the ability of a light source to restore all the colors of the visible spectrum. The IRC of a light source is expressed in the form of a number ranging from 0 to 100, where 100 indicates a perfect light spectrum, ie encompassing the entire visible spectrum. Therefore, this means that this light source makes all the colors exactly. The lower the number, the lower the amount of color returned. Illustration of the IRC Examples of the light spectrum of different IRC The less the source emits distinct wavelengths, the lower the value of its CRI. As a result, fewer shades of color may be able to be reflected from objects lit by this light source. Concretely this means that the objects will lose some color details. When we compare several sources of electrical light, we can see that the ability to render colors (CRI and corresponding values) varies considerab...

Importance of lighting for a hotel

Importance of lighting for a hotel This article presents why using LEDs for hotel lighting . The benefits of LED lighting are numerous, it is worthwhile to dwell there point by point to illustrate the importance of this choice of light in the hotel industry. LED bulbs will be advantageous for a hotel since they have a long life. This point is important when you know the number of bright spots in a hotel. Classic bulbs will wear out quickly while LED bulbs will hold longer, which will benefit the hotel. This saves time on the purchase and maintenance of facilities and saves money because fewer renewals and maintenance means more savings. An effective light source Who says LED light, says more efficient light than a conventional bulb: 60 to 130 lumens / Watt against 8 to 15 lumens / Watt (the lumen quantifies the amount, the intensity of the light emitted by a bulb). In addition, the heat released from the LED bulb is very low, unlike the conventional bulb that heats a l...
