How to choose the power of a bulb for a room?

When you are sitting on the sofa in the living room and relaxing with your family members, you are not interested in bright lights shining directly on your face. So in the living room you will look for soothing and subdued light. If it is possible to adjust its intensity, even better! But in the kitchen, you'll want to be able to flood the space with light. This is a workplace where you want to see everything clearly. What if you like the black lamps for the hall or the ceiling lamps for the living room and you don't quite know which bulb to install?

When picking up a specific light bulb, you should first check the energy class (A is the highest, and each + symbol increases this class). The higher, the better, of course. Secondly, it is worth specifying what kind of bulb we are looking for? Let's start with the functions and the well-known scale of traditional light bulbs, and so on:

1/ peace or v living room – depending on the size, you may need up to 200W in total to illuminate a fairly small living room (from all the bulbs in the room):
a/ the main light source are usually hanging lamps - their power should be about 75W;
b/ desk or standing lamps, especially those for reading, must have at least 40W, and the bulbs should provide diffused light;
c/ wall lamps, e.g. wall lamps, it is enough if they have sources with a power of up to 25W;
d/ night lamps should provide a subtle, warm light, approx. 10-20W.

2/ dining room – if you choose hanging lamps for the dining room – e.g. a light bulb lamp or a light bulb hanging lamp, both proposed by the Danish company from Hubschthat will allow for adequate illumination of the space in this room, they should have a total power of 60W or more;

3/ children's rooms, just like in the living room, it is worth installing several light sources with a total power of 100+W:
a/ quite powerful, even about 60W at the top, for fun,
b/ desk lamp about 40W;
c/ night lamp about 15W.

3/ kitchen, you will need at least one light source with a power of 40-60W;

4/ bathroom, a spotlight with a power of 25-40 W is enough. Alternatively, you can also consider a separate ceiling lamp with a power of about 40-60 W, which will help when washing or cleaning.

How to choose the power of the bulb according to the type of fixture and the function of the lamp?

It is worth remembering that the above should also be corrected depending on the type of fixture and the type of lamp. A wicker floor lamp, for example, will require a different bulb wattage than an incandescent ceiling lamp, which plays a more functional role. As for the type of lamp, approximately, about 400 lumens is suitable for table lamp, and for hanging lamps it may be reasonable to use these brightest bulbs. Therefore, regardless of whether it is a floor lamp or a hanging lamp, well-matched bulbs will create a stylish, balanced, functional and unique interior!

Take into account the selected lighting fixture, no matter whether it is a copper lamp proposed by It's About Romi or a glass hanging lamp from EBB&Flow – in our online store you will find such and such and many other designer products. And always consider the brightness and color of the light emitted by the bulb in the context of the specific fixture.

LED bulbs – which one to choose?

First, ask yourself what type of light you need in your home, in each room. Your decision very often comes down only to brightness and color, or in other words the color of light. What is the difference between brightness and color? Here is a short explanation.

Bulb brightness

In the past, everything was easier because the main determinant of a light bulb was its brightness. Interestingly, it is measured in watts, which is interesting because in fact a watt is a measure of power, not brightness. At that time, there was no problem finding the right product because there was one scale, well known to everyone. When you needed a lot of light, you simply used a 100-watt bulb. And for the proverbial basement, probably 40W. Since the introduction of energy-saving light bulbs, watts have become a less useful measure of brightness because new bulbs use much less energy to produce the same amount of light. Instead of watts, which still confuses many, light output, or brightness, is measured in lumens (lm). The higher the value, the brighter the light. However, new measurements continue to make it difficult for many people to judge the suitability of a light bulb.

How to convert the power markings on LED bulbs?

Once we know what power of the bulb we are looking for, it remains a matter of properly calculating the power for a specific bulb. And here's a note! Please remember that the power expressed in watts for different types of bulbs may lead to wrong choices. It is worth remembering the conversion factors that apply to:
1/ LED bulbs are approximately 6; 
2/ fluorescent lamps approx. 4.6; 
3/ halogens approx. 1.3.

This means that when choosing a 20W LED bulb, we actually get a light source with a power of 20×6, i.e. even over 100W.

How to convert brightness markings on LED bulbs?

As for the current measurement of light bulb brightness on packaging, i.e. lumens, it can be roughly translated into the power of traditional light bulbs as follows:

1/ 100-150 lm (exactly 136 lm) corresponds to a traditional 15W bulb;
2/ 220-250 lm (249 lm) – 25W; 
3/ 410-470 lm (470 lm) – 40W;
4/ 700-810 lm (806 lm) – 60W;
5/ 920-1.100 lm (1055lm) – 75W;
6/ 1,100-1,600 lm (1521 lm) – 100W.

These are indicative data and are intended to show approximately which modern bulb will best fill the place of the previously used traditional bulb with a tungsten filament.

Summary – make friends with LED bulbs, because there is no going back to traditional ones

To simplify the bulb selection process and to summarize the above considerations, we have prepared the infographic below. It allows you to compare the current measure provided by manufacturers, i.e. the brightness of the bulb in lumens, to the well-known measure in watts for both traditional and LED bulbs.

 

When looking for warm, yellow light, we should look for light that is about 2,700 degrees Kelvin, up to a maximum of 3,300K. For comparison, the color temperature of sunlight at summer noon is about 5,000K, and a candle emits light with a color temperature of about 1,600 degrees Kelvin.

Not everyone realizes it, but the color of light affects a lot, starting from our mood and well-being, to the color of vegetables we see on the cutting board, and how we evaluate its freshness and taste. Therefore, it is important to consciously select both the power and color of light. This is important when it comes to lamps above the dining table, but also to all other lamps. The right choice of light color will also make it lamp it will look better. A carefully selected bulb will highlight and present a chandelier of any kind much better.

Color temperature – CRI index.

If you think it's over, it's not. In addition to brightness and color, each bulb has an additional CRI index (CRI). color rendering index). Generally speaking, it means the quality of color rendering by a specific bulb. Therefore, it is a measure of the ability of a given light source to accurately reproduce various colors. Simply put, in the kitchen you want to make sure you install a light bulb that will make your tomatoes appear red on the cutting board, rather than, say, orange or brown. The closer the CRI is to 100, the better. Traditional incandescent and halogen bulbs are close to CRI 100. As for LED bulbs and compact fluorescent lamps, they will have it around 80. However, this level of CRI is still considered acceptable, but it proves that such light sources distort colors to some extent. This is worth remembering.

Appropriate bulb shape, thread, etc. Not only color and brightness are important.

Now that you know what color bulb and what brightness you need in your rooms, you also need to decide which bulb shape you will like. And most importantly, which one will be suitable for the lamp you choose. If you are replacing a burnt out bulb, you can simply replace it with the same bulb. You can take the used model to the store and let experienced employees help you choose a replacement. If you have new ones hanging lamps for the living room, hanging lamps for the kitchen or other rooms or you have simply decided to switch to energy-saving LED bulbs, it may be necessary to choose a different shape of the bulb than before. The choice of bulb shape can also be important. Especially when the lamp is such that the bulb is visible.

Each of the different shapes provides slightly different radiation and angle of incidence of light. From almost 360-degree dispersion to a narrow, directional beam. Generally speaking, the shape you choose can be based on your personal preferences and what looks best in a particular setting.

Also pay attention to the bulb thread, usually it is either E27 or the smaller E14. However, checking this small detail can save you the effort of replacing a bulb.

Selected furniture and lighting for this interior

One of the changes taking place in lighting today is that some new fixtures are equipped with integrated light sources, such as individually designed LEDs, which do not need to be replaced. In such a setting, we cannot change anything when it comes to the nature of the light, its color and brightness. Check this carefully before purchasing, because you definitely want to be sure that you will be satisfied with the light emitted by such devices.

Which LED bulbs should you choose? - summary

It cannot be denied that LED bulbs have a number of unquestionable advantages. They last longer, are less prone to failure, provide an effective light source, and also save electricity, which translates into lower electricity bills. However, choosing the right LED bulbs for a specific room may not be so easy, especially since there are many different types of this product on the market with different power and color of light. We hope that our comprehensive guide will help you

 

 

EBB&Flow blown glass lamps for home and more. Great!

See, in our opinion, the best series of lamps from the Danish company EBB&Flow, little known in Poland but valued in Western Europe. All projects at EBB&Flow start with its owner, Susanne Nielsen, whom I had the opportunity to meet in person at one of the fairs in Paris. For each new idea, Susanne uses the classic British and Nordic style as a starting point, she has a passion for natural materials, glass, crystal, metal and textiles, as a result of which she created an original style that combines light and glass, fills them with lightness, simplicity and adds a touch of modernity.

 

Retro style lighting – which lamps to choose?

Retro lamps are mainly multi-arm chandeliers with glass shades suspended in the living room and contrasting with modest single hanging and standing lamps. Single hanging lamps found their place in the kitchen, small rooms and the hall. Wall lamps work well in the hall, bathroom and living room. What do you need to know about lamps in this style and what should you pay attention to? We give you a hint!

 

Scandinavian, i.e. minimalist. Not always. Get to know the true features of style straight from the north

At first glance, Scandinavian style and minimalism may go hand in hand. These terms are often used interchangeably by people talking about simple, yet warm and practical arrangements. In this context, it is assumed that they are synonyms, and there is a lot of truth in that. Indeed, contemporary design has created an image of an ideal, orderly interior. These are almost always white walls and carefully selected plants in fashionable pots. These also include neutral knitted blankets and other Scandinavian textiles, and above all, clean surfaces and undemanding spaces. Although the Scandinavian style and the minimalist style mix very well with each other (and, admittedly, often intertwine), there are important differences. What?

Frequently asked questions (FAQ)

How to choose the right bulb power for a hanging lamp? +

For hanging lamps in the living room or dining room, it is best to choose LED bulbs with a power of 6-10W (equivalent to 60-75W of a traditional light bulb) and a warm light color (2700K). If the lamp has an open glass shade, it is worth choosing decorative filament bulbs that not only illuminate, but also decorate the interior.

At what height should the lamp hang above the table? +

A lamp hanging above the dining room table should be suspended at a height of 75 cm to 90 cm from the table top. This prevents blinding of people sitting at the table and at the same time optimally illuminates the dining area.
