Many people only care about wattage and brightness when buying a light. But the truth is, light affects not only your ability to see clearly, but also your emotions, your biology, and your vision in the long run.
To choose the right light, start with important technical factors such as: color rendering index (CRI), flicker, color temperature (CCT), blue light, illuminance (lux)...
Color rendering index (CRI), preserves the true color of objects
CRI (Color Rendering Index) is an index that shows the ability of a light source to reproduce colors faithfully. The higher the CRI of a lamp, the more similar the color of objects under the light is to the true color under natural light.
- You should choose lamps with CRI of 80 or higher for common living spaces such as living room, bedroom, kitchen...
- For areas requiring high color accuracy such as galleries, studios, and high-end restaurants, CRI lamps of 90 or higher are preferred.
Lamps with low CRI often cause color distortion, objects look dull, reduce aesthetics and create discomfort when viewed for a long time.
Flicker index, avoid eye strain, headaches
A lamp may emit light that looks smooth to the naked eye, but can still cause high-frequency flickering – a leading cause of eye strain, headaches, and even brain damage with long-term use.
- “No Flicker” standard lamps are the ideal choice for spaces with continuous use such as classrooms, offices, kitchens, or children's bedrooms.
- Especially important for people who work online, read books or use screens a lot, because flickering light will amplify visual fatigue.
80% of users don't notice their lights flickering until they switch to a standard light and notice the difference from the first time they turn it on.
Color temperature and light suitable for each space
Color temperature (CCT – Correlated Color Temperature) is measured in Kelvin (K), which determines the color tone of light. Each color temperature will create a different feeling in the living space:
- 2700K – 3000K (yellow light): Creates a warm, relaxing feeling, suitable for bedrooms, living rooms, and resting spaces.
- 3500K – 4500K (neutral light): Brings gentleness and naturalness, suitable for kitchens, dining rooms, and family rooms.
- 5000K – 6500K (cold white light): Bright, supports high concentration, suitable for offices, bathrooms, hallways or garages.
Choosing the right color temperature will help create the right atmosphere for every use, from relaxation to concentration.
Limit blue light, protect eyes and sleep
Blue light isn’t always bad, it helps you stay awake during the day. But in the evening, blue light suppresses the hormone melatonin, disrupts sleep, and causes visual stress, especially for children and people who work late.
Choose LED lights with blue light filtering technology such as Low Blue Light or ComfortView, especially for desk lamps, study lamps or lamps used in bedrooms. Also, avoid using cool white lights (6000K+) after 9pm.
Combine the right type of light – right position – right function
An effective lighting system is a harmonious combination of many types of lights, scientifically arranged according to each functional area:
- Overall lighting: Recessed lights, LED panels, LED ceiling lights help distribute light evenly throughout the space.
- Accent lighting: Pendant lights, wall lights, and spotlights create artistic lighting effects and increase the depth of space.
- Functional lights: Table lamps, study lamps, wall lamps used to serve specific living needs, such as reading, working, etc.
Additionally, you can use dimmable lights or connect them to a smart home system, allowing flexible lighting customization based on time and activity during the day.
Don't forget to check the illuminance (lux), because too bright or too dark is not good.
Illuminance, also known as lux, is the actual amount of light that falls on the surface you use. For example, a desk, countertop, or floor. If the lamp is placed too far away, at the wrong angle, or with a narrow beam angle, the light may not be focused enough on the necessary area, causing long-term damage to the eyes.
You don’t need any special equipment, just a smartphone and a lux meter app, you can check the illuminance in each room. Here are the recommended lux levels for common spaces in the house:
- Work and study desk: 500 – 750 lux
- Kitchen and cooking area: approximately 500 lux
- Reading corner, relaxing sofa: 300 – 500 lux
- Living room (backlight): 200 – 300 lux
- Corridors, walkways: 100 – 150 lux
“Standard lighting” is the foundation of modern living space
Don’t underestimate the role of lighting in interior design. When choosing a lamp, consider the above factors carefully. A beautiful lamp is not necessarily a good lamp. And a “bright” lamp is not necessarily a standard lamp. Appropriate lighting not only makes the house more cozy and comfortable but also contributes to improving the health and living experience of the whole family.
