How to choose your G9 LED bulb

If you know how to choose a traditional incandescent bulb, choosing a G9 LED bulb is different in some ways. Here are some things to consider when choosing the right G9 LED bulb for your needs.

#1 - The lumens

Lumens are to G9 LED bulbs what watts are to incandescent bulbs. When buying bulbs, you are probably used to looking for watts as an indication of the bulb's wattage. For G9 LED bulbs, there is no correlation between watts consumed and brightness produced. Instead, another form of measurement must be used: lumens. The lumen (lm) is the actual measure of brightness provided by a bulb, and it is the number you should look for when purchasing G9 LED bulbs.

For reference, here's a chart that shows the watt-lumen conversion for incandescent bulbs and LED bulbs, in general:

Lumens Incandescent Bulb LED bulb
1600 lm 100 W 16-20 W
1100 lm 75 W 9-13 W
800 lm 60 W 8-12 W
450 lm 40 W 6-9 W

#2 - The color temperature

Incandescent bulbs typically emit a warm, yellowish hue, but LEDs, especially G9 bulbs are available in a wide range of colors. The two most popular colors available for LED bulbs are soft white (also called warm white) and bright white (also called daylight). More technically, the color of light on the white light spectrum is called color temperature, and it is measured in Kelvin. The lower the number, the warmer (yellow) the light.

#3 - Variable intensity or not

Because of their circuitry, G9 LED bulbs are not always compatible with traditional dimmers. In some cases, the switch must be replaced. Other times, you'll pay a little more to get a compatible G9 LED bulb. The first thing to do if you are buying G9 LED bulbs that you want to use with a dimmer switch is to make sure you are buying models that are dimmable. Most manufacturers offer non-dimmable G9 LED bulbs without any on-board dimming hardware, and while these are fine if you want to save a buck or two on a G9 LED bulb for a non-dimmable fixture, they won't be the best choice if you like dimmed lights.

#4 - The design

In contrast to incandescent bulbs, LED bulbs, including G9 models, come in a variety of shapes and sizes. Many G9 bulbs offer a high-end look and elevated design elements compared to other halogen lighting solutions. All of this gives you the ability to play with the aesthetics and visual appeal of your interior or exterior. There are spiral bulbs, large formats, globes, golf balls, spotlights, floodlights. Some can resemble candles that give it a more vintage look. With so many options, you're spoiled for choice. In general, large bulbs go with large lamps and small bulbs go with smaller lamps. Make sure the bulb fits perfectly inside the lamp.

#5 - The manufacturing quality

Manufacturing quality is also important when choosing a G9 LED bulb! LEDs in general are known for their long life, but if manufacturers do not use quality materials, it can be detrimental. Always choose a reliable manufacturer with good reviews, even if it costs more. Poor quality G9 LED bulbs can be out of use before an incandescent bulb. You probably know that LED bulbs are much cooler than their incandescent cousins, but that doesn't mean they don't produce heat. LED bulbs do get hot, but the heat is dissipated through a heat sink at the base of the bulb. That's why it's a good idea to stick with incandescent, fluorescent and halogen bulbs for enclosed fixtures.

How does a G9 LED bulb work?


G9 LED bulbs work the same way as almost any other halogen bulb. These typically have a tungsten filament and a fill gas that contains traces of iodine or another halogen. The tungsten filaments last longer than in incandescent bulbs because of the "halogen cycle" phenomenon. As the metal evaporates from the heat inside the bulb, the halogen causes it to redeposit on the filament. Halogen bulbs must reach outdoor temperatures of at least 120°C for the halogen cycle to occur.

It is because of this cycle that the average halogen bulb lasts several times longer than an incandescent bulb. Although they generally burn hotter than incandescent bulbs, they are also more efficient. G9 LED bulbs are typically designed to last 15,000 hours of active use on average.

Halogen bulbs with this type of base are designed to operate on 120-130 volts of electricity, and they are generally available in a wide range of wattages. Higher wattage equals higher light output. Like G4 LED bulbs, G9 LED bulbs consume very little energy. The good news is that unlike G4 bulbs, G9 models do not require a special LED transformer, so you can simply insert them into your existing G9 fixtures.

G4 LED light bulb or G9 LED light bulb

G4 LED Bulb

G4 LED bulbs are a natural replacement for G4 halogens. They are small bulbs that require a transformer to operate and can be installed very simply (they have a 2-pin connection). G4 LEDs are up to 80% more efficient, have a lifetime up to 10 times longer than a traditional bulb. They do not emit heat and are more durable. G4 LED bulbs are used to illuminate small spaces such as cabinets. G4 LED lamps have high brightness and efficiency. They are the perfect solution for replacing traditional bulbs. You get perfect brightness with much lower power consumption.

G9 LED Bulb

A traditional incandescent bulb G9 consumes 20W and its equivalent in LED around 2 or 3 watts. We can deduce that the energy saving is very considerable, especially if we change several bulbs of this type and that they are bulbs that we burn a long time daily. One of the main advantages of a G9 LED bulb is its lifespan, which can reach 50,000 hours. Its uses are similar to those of G4 LED bulbs, being mainly oriented towards small spaces where a large amount of light is needed (inside cabinets, decorative lamps, etc.).


The biggest difference between the two is that G4 LED bulbs tend to be low voltage bulbs, so they should be used with a compatible transformer, while G9 LED capsules work with mains voltage. In reality, your choice will be dictated by the electrical installation your home has.

Why buy a good G9 LED bulb?

Long-term economy

G9 LED bulbs are like hybrid cars: more expensive initially, but cheaper to use. It used to be that you could buy an incandescent bulb at the hardware store for less than a dollar. Then LED bulbs came along, most of them costing much more. Fortunately, several years of development and have brought the price down to the point where you can find many G9 LED bulbs for 5 euros or less.

More efficient than a halogen G9 bulb

With an average life of 15,000 hours, a G9 LED bulb lasts up to 7 times longer than a G9 halogen bulb. With a very low power, a G9 LED bulb achieves the best light performance. In addition, G9 LED bulb does not contain any harmful substance like mercury.

Works in cold conditions

Traditional light sources do not like cold. When the temperature drops, light sources, especially fluorescent lamps, require higher voltage to start. LED lamps, especially G9 LED bulbs, on the other hand, work better in cold weather down to 5°C. That's why G9 LED bulbs can be found in refrigerators and outside the house, on a terrace, for example.

Design flexibility

G9 LED bulbs are very small. This means that they can be used in almost any application. Remember, their original use was as indicator lights on circuit boards. So think of the options this gives you in terms of lighting.

Instant lighting

If you're looking for a light that needs to come on quickly, opt for a G9 LED bulb. They can turn on and off instantly. Think about how a fluorescent light flickers when you turn it on. It often takes two to three seconds before it is fully lit. With a G9 LED bulb, you won't experience this.

The best brands of G9 LED bulbs

In our opinion, the best brands of G9 LED bulbs in 2022 are :


DiCUNO is a company specialized in manufacturing and marketing LED lighting. The brand excels in the new COB (Chip-on-Board) LED lighting technology.

Use G9 LED bulbs as ceiling lights

G9 LED ceiling lights simply modernize your home and office. They can be used in place of traditional fluorescent lights to save money on the electricity bill. Ceiling lights are much better than conventional tube lights and are a must consider.

G9 LED bulbs are perfect for makeup mirrors

There are many home mirrors today that use smart lighting to illuminate the face, preparing for the perfect makeup application. This smart lighting often comes in the form of compact G9 LED bulbs.

Use a G9 LED bulb with your chandeliers and pendant lights

Again, because of their small size, G9 LED bulbs can fit perfectly into stylish fixtures such as pendant lights and chandeliers, quickly becoming the focal point of any room.

Safety precautions

One of the reasons G9 LED bulbs light up so brightly is that they operate at extremely high temperatures. You should avoid touching these types of bulbs directly with your hand to avoid potentially serious burns. Also, oils on the skin can penetrate the semi-permeable glass of these bulbs, which can compromise their long-term effectiveness. Any grease or oil transferred to the surface of a G9 LED bulb can be removed with alcohol slightly diluted with water.

Avoid turning on your G9 LED bulbs directly after cleaning it

Dust deposits increase the light sensation of a bulb, so it is best to leave it off for a few moments after cleaning.


How to recognize a G9 LED bulb?

The easiest way for a person to identify a G9 LED bulb is to look at its base. Most standard bulbs for household lamps and fixtures have what is called an "Edison" screw socket, which is a round, ridged metal pin or projection that physically screws into a base. G9 LED bulbs do not have this. Instead, they have two looped thin metal prongs that sometimes look like rigid wires. The bulbs themselves can come in different sizes and styles, though most tend to be long and somewhat thin.

Do I need to clean G9 LED bulbs?

It depends on how dusty it is. Generally speaking, bulbs are not consumables that need to be cleaned very often. However, many manufacturers recommend wiping them G9 LED bulbs with alcohol if you are sure they are very dirty. Of course, wait until the bulbs have been off for at least an hour before cleaning them.

What is the difference between a G9 LED bulb and a G9 halogen bulb?

A G9 LED bulb has a number ofmajor advantages over a halogen G9 bulb. The main advantage is that an LED model uses only 10% of the electricity used by a halogen model. However, the main problem with this technology is that it tends to be bulkier and often doesn't fit into certain types of fixtures.

What are the most common uses of G9 LED bulbs?

G9 LED bulbs can be used in many practical applications. They are often perfect for office pendant lighting and accent lighting. It is also often used in desk lamps and under cabinet lighting, as well as in small consumer fixtures such as reading lamps and makeup mirrors.
