There are several types of surface-mounted downlights, including rail-type surface-mounted downlights, ceiling-type surface-mounted downlights, hanging wire-type surface-mounted downlights, etc.
How to choose a downlight?
The quality of the downlight mainly reflects the quality of the light source, power supply stability, lamp shell quality and heat dissipation, spot effect, etc. The light spot in the center is obvious, and the transition to the outer circle is natural.
The choice of downlights should be based on the decoration style, application scenarios, house layout, usage, etc. You can refer to the downlight purchasing experience sharing.
1.Recommended distance from the wall
Surface-mounted downlights are generally 20-40cm away from the wall, and the spacing between multiple ones is 100-120cm. In addition, the angle of surface-mounted downlights is not adjustable and can be installed without opening holes.
2.Lighting purposes
Single-head surface-mounted downlights can be used for background wall lighting and auxiliary lighting, and multi-head ones can also be used for accent lighting.
Background wall lighting, auxiliary lighting areas: background wall, entrance hall, aisle, balcony, living room, bedroom
Key lighting areas: living room main light, study main light
3.Color rendering index recommendations
The color rendering index is the true color of an object restored by light. Generally speaking, the higher the color rendering index, the closer the color of the restored object is to the true color.
Generally, the color rendering index Ra>85 can fully meet the requirements of conventional home lighting. The specific situation can be selected according to personal circumstances. .
4.Anti-dazzling suggestions
Generally, glare is divided into two types: direct glare and indirect glare.
Direct glare is also divided into disability glare and discomfort glare.
Disabling glare refers to a direct light source shining directly into the eyes, causing blurred vision.
Discomfort glare refers to light sources that cause psychological discomfort to people. Simply put, installing many lamps with exposed light sources in the room can easily create a psychological connection to the disabled entrance.
Indirect glare refers to reflections caused by objects being illuminated by a light source.
There are four major categories of anti-glare lamps: deep barrel anti-glare/large shading angle, honeycomb network anti-glare, and different colors of anti-glare covers
5.Recommendations for downlight color temperature for basic lighting:
Living room: Warm light and natural light are recommended. Natural light is recommended for the elderly room to ensure lighting needs.
Restaurant: Warm light and natural light are recommended, and the choice is based on the family atmosphere.
Kitchen: Natural light can meet the basic requirements. If you like something brighter, you can choose white light.
Bedroom: It is recommended to choose warm light, which can create a warm atmosphere and effectively aid sleep.
At the same time, please note: In order to make the lighting effect more coordinated, it is recommended to use the same color temperature in the same space to avoid causing eye discomfort.
6.Calculation of space wattage
Here is a universal calculation formula: the total wattage required for the space = space area × 3. For example, the total wattage required for a 10㎡ space is 10 × 3 = 30W. As long as the wattage of all lamps is added up, it will be around 30W. That’s it. If you want brighter or darker spots, you can adjust it up or down within this value range.
Note: The most scientific calculation method still requires using lighting design software to generate illumination false color maps to feel the effect of the lighting scene in advance.
7.Suggestions for Blu-ray and video flashing
The blue light wave peak is mainly related to the color temperature. Generally, lowering the color temperature can effectively alleviate it. With the popularization of constant current drive power supply, video flashless has basically become standard, so there is no need to worry too much.

In short, the main purpose of surface-mounted downlights during decoration is to release floor height without relying on the ceiling, and at the same time, they do not want to affect the lighting artistic effect.
