How To Choose The Proper Lamp For Your Home

As we know, lighting plays a vital role in our home decoration. Bad lighting may destroy the whole interior design and affect our mood.

There are three parameters that can help us to choose the suitable lamp: illuminance, color temperature and color rendering index

1.Illuminance

It’s a measurement of the amount of light that reaches an area of a surface. It is used to describe the brightness of light and its unit is Lux (= lumen per square meter)

It’s not that lamp with bigger power has higher brightness as different lamps differ greatly in luminous efficiency. For example, LED light of 8W is as bright as the incandescent light of 40W.

The usual illuminance applicable to home lighting is: 100-200Lux for hallway and storeroom, 100-300Lux for living room, 100-200Lux for bedroom, 250-500Lux for working area, and 100-200Lux for dining room, kitchen and toilet.

2.Color Temperature (CCT)

It refers to the color of light. Color temperature is conventionally expressed in kelvins, using the symbol K.

As we think about which type of lighting to use in our home, we should consider how we can use color temperature to optimize our environment.

The picture below is the color temperature range of white light.

For home lighting, the brightness required for different functional areas is different. Warm white light can help to create a relaxed atmosphere while cool white light can help us to be concentrated. Thus, from the use of room, cold light source is applicable to study, living room, kitchen, etc. And warm light source is applicable to bedroom, bathroom, balcony, etc.

3. Color Rendering Index (CRI)

A color rendering index (CRI) is a quantitative measure of the ability of a light source to reveal the colors of various objects faithfully in comparison with an ideal or natural light source.

CRI of sunlight is 100. CRI of outdoor lighting should be over 65 while CRI of indoor lighting should be over 80. Lamp with a high CRI can make colors more realistic while lamp with a low CRI will cause colors to distort and even aggravate eye strain.

Illuminance, color temperature and color rendering index influence each other. Under the appropriate illuminance, choose the lamp with proper color temperature and color rendering index, can we have a good sensual experience.
