LED recessed downlights are increasing in appeal among clients trying to find lighting for numerous purposes. It is tough to wonder why– LED bulbs are extremely efficient, low-maintenance, and environmentally friendly, while downlights are extremely flexible. They can be used as job lighting to produce focal points (for instance, in the cooking area), or be tactically placed all around the space to illuminate the entire area as the basic lighting.


The key to accomplishing the desired impact is the right number of lights. The final number will depend on several elements, such as the size of the space, its decoration and use, the amount of natural light, and so on. Nevertheless, there are some basic rules that you need to follow to determine the number of downlights you will need for lighting the space appropriately. To learn more about the information, just keep checking out!


Placing Downlights in Different Rooms

Kitchen area

When you think about task lighting, the kitchen area is most likely the very first space that comes to mind. Work areas should be well-lit, so you can either set up a bigger number of smaller-sized lights or pick larger square downlights with more lumens. If you plan to install lights in your restroom, you need to pay more attention to the IP scores, which refer to the waterproofness of the bulbs.


The rule of thumb here is to figure out the square meters of the space (multiply the length by the width) and the lux measurements (how brilliant light is on the surface area, that is far from the source of light– one lumen per square meter). Multiply one by another, and you will get the number of needed lumens. Remember that it is only an idea and may not apply to all interiors. For instance, if you have dark walls in a space, it may be a good idea to add 10 lumens more per square meter. You may also have some individual preferences, and they should be considered as well. If you choose brilliant spaces, simply go all out.


The ideal measurements here would be 150 lux.


Consider the Ceiling Height

When it pertains to planning the lights according to your ceiling height, the guideline is to divide it by 2. For instance, if your ceiling is 3 meters high, the downlights need to be around 1.5 meters apart from each other. Nevertheless, remember not to follow any rules blindly. You might desire the lights even more apart; some areas might not require to be as well-lighted as others if you pick brighter bulbs. Your decor style is also of great significance, along with the purpose of the space. It is best to select the general lighting with measurements of 200 lux.


Think about the Lights

Undoubtedly, not all downlights are the same, so it is crucial to think about the variables, specifically if you opt for some non-standard lighting options. LED downlights are a fantastic choice because of their flexibility and effectiveness, but make sure you do not make any hurried decisions. Plan the lighting thoroughly, considering all the elements and variables– just then can you achieve the desired effect and be pleased.



When it comes to bathrooms, it is very likely that you use this room for putting your make-up on or shaving; therefore, you will need quite a 4 inch led recessed lighting around the sink and the mirror. However, you most likely like to unwind there too, particularly if you have a bath, so you may wish to have the ability to alter the environment. Job lighting must be put around 0.75 meters above the surface area with optimal lux measurements of around 300.


Bed Room & Living Room

Bedrooms and living rooms are comparable due to the fact that, in both, you will most likely go for the most varied lighting of all rooms. On the one hand, you want to be able to develop a cozy, lovely environment; on the other hand, both areas might require task lighting (for instance, for reading). That’s why dimmers are a popular choice, particularly for living spaces.


Final Thoughts

The number and positioning of downlights can make or break the whole space, no matter the design. Improperly lighted space will be uncomfortable to hang out in, and you probably wouldn’t like to prevent any rooms in your own house.


Mind the Edges

You don’t wish to place any lights too near the edges of your ceiling or walls, as it will create shadows, which won’t look great in any space. Shadows make the area appear smaller, plus, they create an unpleasant environment. Usually, it is recommended to keep downlights a minimum of half a meter far from the edges.


Obviously, every room is different and needs to be treated individually, however by following a number of simple rules, you will make the whole process of picking the lighting a lot easier. If you feel like this is too much, you can also find special calculators readily available online, or get in touch with a professional for customized recommendations.


Too Many Are Better Than Too Few

It is best to get too many lights than risk dark spots if you ever have any doubts. If you end up overlighting your space, all you need is a dimmer switch to adjust the lighting. Dimmers will allow you to have it all– a bright, well-lit room as well as a cozy, romantic environment when required. Bear in mind, though, that numerous LED downlights may not work well with some (or all) dimmers, so ensure to get in touch with a professional very first.


Determine How Much Light You Need

The basic brightness of the light is measured in lumens. Make certain not to puzzle them with watts, which describe how much electrical energy a bulb needs to produce light. Start your preparation with centerpieces and prepare the rest downlights in the space around them.


A light with a narrower beam angle will be best for job lighting however might become irritating if used as a part of basic lighting.


Plan It Carefully

It is constantly an excellent idea to put everything on paper initially, even if you do not work with an expert designer. It may be challenging to imagine all of it in your head, and producing a plan will provide you with a much-needed perspective. This way, you’ll be able to make some modifications in the preliminary stages of the project, so that you’ll prevent making a mess in the future. It will assist you to figure out whether your ideas are actually worth thinking about.


A regular house lighting must be around 150 lux. However, for studying or working, you will require around 500 lux for optimal illumination, while more comprehensive jobs will need a minimum of 750 lux.


Determine the Focal Points

When you have a self-made plan of your space, make sure to include furniture in it to be able to identify all the required focal points that will need more light than other locations. For example, when it pertains to the kitchen area, you most likely would like your countertops to be well-lit, while in the restroom, there need to be more lights around the mirror and the sink.
