Halogen bulbs with clear and pleasant light
Here on the site, you will find our complete selection of halogen bulbs, which provide a clear and pleasant light.
Halogen bulbs come in many varieties, different socket types, different color temperatures, and with different lifespans.
Common to them is that halogen bulbs provide a very clear light, making them perfect for example in the bathroom, where you need bright light to do your hair, trim your beard, or apply makeup.
Halogen bulbs ignite quickly, almost instantly, which means you don't have to wait for the light to reach its full brightness; many models are also dimmable and can be adjusted in strength.
If you are unsure which halogen bulb you need, read on below and get help choosing the right halogen bulb for you.
5 things you should know when looking for halogen bulbs
There are many designs, socket types, and models of halogen bulbs, so it can be a challenge to find the right halogen bulb.
Below you will find some things that are good to know when searching for halogen bulbs.
#1 - Socket type for halogen bulbs
There are several different socket types for halogen bulbs, and the socket type is quite important to pay attention to, as the halogen bulb cannot be installed in the lamp if it has the wrong socket.
The socket types include:
- G4
- G9
- GU4
- GU5.3
- GY6.35
Below you can see a brief description of the different socket types:
Socket type | Description |
G4 | A fairly small halogen bulb with two pins. G4 is often used in spotlight lamps, and this socket type is chosen when there are two small holes in the lamp's socket. |
G9 | A small halogen bulb, which like G4 is a pin bulb, but here the pins are shaped like small hoops. The fitting for a G9 bulb is often a rectangular fitting with a wide rectangular hole. |
GU4 | A spotlight bulb with pins similar to G4, and the fitting also resembles that of G4; here the bulb is somewhat larger and the pins are mounted in a rectangular part of the bulb. |
GU5.3 | A halogen spotlight that resembles GU4 in design but has slightly wider pins. |
GY6.35 | Resembles G4 in size and design, but the pins are somewhat thicker. |
In general, halogen bulbs are designed for spotlight lamps, and therefore the socket types are quite small, as there often is not much space in spotlights.
#2 - Lifespan of halogen bulbs
The lifespan of halogen bulbs can vary greatly, so it is beneficial to look for a halogen bulb with as long a lifespan as possible.
The lifespan is measured in hours and indicates the expected number of hours the halogen bulb can be lit before it needs to be replaced.
Most halogen bulbs have a lifespan of about 2000 to 2500 hours, equivalent to 105 days of continuous lighting, but it is possible to get halogen bulbs with a lifespan of up to 4000 to 5000 hours.
If you use your halogen bulb in the bathroom, it will on average be lit for about 90 minutes a day, which means that with a lifespan of 2500 hours, the bulb can last for about 4-5 years.
#3 - Color temperature of halogen bulbs
Kelvin is the unit of measurement for the color temperature of light, and the number of Kelvin indicates whether the light is cold or warm in color.
Warm light is often yellowish or reddish in hue, while cold light is bluish in hue.
The light's color temperature can be interesting when you need the light to create a specific atmosphere in a room; for example, you can create coziness by choosing a warm light with a low number of Kelvin.
You can also give your brain better conditions for focus and concentration by choosing a color temperature that is as close to daylight as possible, thus a cold light, by selecting lights with a high number of Kelvin.
Halogen bulbs often have a relatively high number of Kelvin, usually between 2700 and 3000 Kelvin, which falls under the cold light category.
Halogen bulbs resemble daylight and provide a cold and very clear light that works really well with work lamps or at a desk.
Therefore, halogen bulbs are often used in spotlights, work lamps, and up-lights lamps, as they provide a very powerful and clear light that makes it very easy to see what you are doing.
#4 - Strength of halogen bulbs
The strength of halogen bulbs is often indicated in Watts (W), but it is not the same Watt classes you know from traditional incandescent bulbs.
We have therefore created an overview of what the different strengths in halogen bulbs correspond to in incandescent bulbs.
Halogen bulb strength in Watts | Equivalent to incandescent bulb strength in Watts |
7 W | 10 W |
14 W | 15 W |
14.3 W | 20 W |
19 W | 25 W |
25 W | 40 W |
28 W | 40 W |
35 W | 50 W |
50 W | 60 W |
140 W | 175 W |
160 W | 200 W |
400 W | 500 W |
#5 - Types of halogen bulbs
Halogen bulbs come in many designs, and as a general rule, these are divided into 3 types:
- Halogen bulbs
- Halogen spots
- Halogen tubes
Halogen bulbs
Characterized by being either the very small bulbs or small bulbs integrated into a large bulb, resembling traditional globe bulbs, often with an E27 socket.
Otherwise, it is standalone pin bulbs designed for lamps that do not leave much space for the bulb, such as spot lamps.
Halogen spots
Is a halogen bulb shaped like a spotlight, with a sort of shade around the halogen bulb and a lens that seals off the spotlight.
Typically, spots with pins or hoops can be inserted into spotlight lamps with a bit more space, or used in wire systems that you may remember from the 1990s.
Halogen tubes
Halogen tubes resemble a small fluorescent tube and provide a very strong light; they are often used in work lamps and can be found with strengths up to 400 Watts.
Halogen tubes generate considerably more heat than other forms of halogen bulbs and therefore often require a special casing that can withstand the heat.
Phasing out halogen bulbs
In 2018, the EU Commission initiated a phase-out of halogen bulbs, meaning they can still be sold but not produced going forward.
The halogen bulbs sold on the market today are thus the last ones available, so if you have a lamp or spotlight designed for halogen bulbs that you are really fond of, it may be time to buy extra halogen bulbs for it.
It is still completely legal to sell halogen bulbs, and it is also fully legal to use halogen bulbs in your lamps at home.
