Lighting styling knowledge and techniques

Just as you can change the layout of your furniture or the color of your walls, you can greatly change the atmosphere of a room by using lighting. How to arrange the light and where to shine it? How to combine the strength and weakness of the light? We will introduce the knowledge and techniques of lighting styling with reference to the book "Laws of Scandinavian Interior Styling," which is also available at Greenwich.

Rule of 5 to 7

Regarding the number of light sources, basically, each room needs at least 5 to 7 light sources. Check how many lights there are in each room and whether the lights you have are functioning as intended in the room and place where they are placed. Not only do you have a sufficient number of lights, but it is ideal to have at least one of each of the following categories.

① General lighting: Lighting fixtures that spread basic light throughout the room

2) Task lighting / functional lighting: reading lights for armchairs and sofas, lighting for kitchen counters and desks

3. Point lighting: Accent lighting, spotlights, lighting for walls with frames, artwork, and bookshelves

4. Mood lighting / decorative lighting: Lamps for creating an atmosphere, small dimmable lamps, chain lights, lanterns, oil lamps, and other flame-based lighting.

For proper lighting styling, not only the number of light sources but also the position of the lamps is important. In particular, if the lighting above the dining table is too high, it will be dazzling and uncomfortable when you sit down. Conversely, if it is too low, you may hit your head on the shade when you stand up.

Lighting above a dining table should be 55cm to 65cm above the table top (based on the position of the light source inside the lampshade). At that height, the whole table is illuminated without dazzling anyone sitting there or blocking their view with a lampshade. The same idea applies to kitchen islands and counters.

If you are hanging several lamps next to each other, the distance between them should be approximately 1.5 times the width of the lampshade .

In relaxing spaces such as living rooms, the point of "not being too dazzling" is particularly important. To avoid glare or difficulty in seeing when sitting on a sofa or armchair, consider the height and angle of your eyes when you are sitting, and decide the direction of the light, the height of the wall lamp, and the position of the table lamp.

Useful lighting terms to know

Watts ( W )

A unit of power consumption. For lighting fixtures that use incandescent bulbs, the wattage is an indication of brightness.

Room size / Lighting wattage

4.5 tatami mats /60 to 180W

6 tatami mats /100 to 240W

8 tatami mats /220 to 320W

10 tatami mats /300 to 400W

In the case of LEDs and LED bulbs, since they can achieve the same brightness as incandescent bulbs with less power consumption, their brightness is expressed in lumens ( lm ).

Lumen ( lm )

A unit of light emitted by a light source. A larger number indicates stronger light, and a smaller number indicates weaker light. When installing an LED light bulb, choose it based on lumens. When choosing the brightness for LED lighting, calculate by multiplying the number of tatami mats in the room by 400lm (for example, if the room is 6 tatami mats in size, a brightness of 2400lm is required).

Kelvin ( K )

A unit of color temperature of a light source. A low K (Kelvin) value means red, a high K value means white, and a higher value means bluish-white. Generally, there are five types of light colors: "Incandescent ( 2600K to 3250K )", "Warm white ( 3250K to 3800K )", "White ( 3800K to 4500K )", "Daylight white ( 4600 to 5500K )", and "Daylight ( 5700K to 7100K )".

Incandescent color: Close to orange, with a warm color. It has the lowest brightness of the five types, and is suitable for relaxing spaces.

Warm white: A yellow color that blends in more naturally than white. Compared to incandescent light, which has a lower color temperature, it is whiter, so it creates a brighter, more relaxed atmosphere.

White: A slightly yellowish white. Recommended for those who find pure white too bright, or for spaces for studying, reading, working, etc.

Neutral white: White that is close to white. Suitable for spaces where you want to see brightly and clearly.

Daylight: A slightly bluish white color. This color is similar to sunlight at noon on a sunny day, and is suitable for tasks that require concentration or for spaces that need to be brightened.

Ra value

A unit of color rendering. It ranges from 0 to 100. The higher the number, the more natural the color appears, and the lower the number, the greater the color deviation. For general indoor lighting applications such as homes, offices, and stores, an average color rendering index ( Ra ) of 80 or more and less than 90 is considered preferable.
