Main Parameters When Choose Modern Circular Lighting

When choosing modern circular lighting, you need to learn the main parameters.

 

How many watts of cicurlar chandelier light does it take to be bright enough?

Which lamp is good quality?

There are so many circular chandelier lights, how to choose the right one?

 

There are Parameters you need to understand when choosing lights

 

1. Luminous flux

The luminous flux of the lamp determines the brightness of the space. Therefore, the first step in choosing a lamp is to learn to judge how many lumens of lamps are needed for different spaces to meet the lighting needs of the environment.

The luminous flux of a lamp is the light intensity, measured in Lux, and refers to the luminous flux of visible light received per unit area. In other words, this illumination is used to answer the question of the brightness of light, that is, "Is this light bright enough?"

 

Standard values of illumination for residential buildings:

Living room: general area 100lx, writing and reading area 300lx

Bedroom: General area 75x, writing and reading area 150lx

Kitchen: general area 100x, workstation 150lx

Restaurant: 150lx

Bathroom: 100lx

 

2. Anti-glare index

Different environments have different architectural lighting standards. For daily use, the glare value URG≤19 is generally selected.

 

3. Color rendering index

Color rendering index is a parameter common to all light sources, which is the ability to restore colors. The color rendering index of daylight is 100, incandescent lamps are also 100,energy-saving lamps are 80-90, and LEDs are 80-99.The lower the color rendering index, the more distorted the color appears to the naked eye.

 

4. Color temperature

Higher the color temperature, the whiter the light,and the lower the color temperature, the warmer the light.For general rest areas, 2700K~4000K is more suitable. Especially at night, do not use a color temperature higher than 4000K.

 

Many customers prefer white light with a higher color temperature (above 5000K), believing that this color temperature can make people concentrate, see things more clearly, and help improve learning and work efficiency.

 

But many times a place will have multiple functions, such as a bedroom. In addition to sleeping, you can also study, read, entertain, etc. in it. Different functions require lamps with different color temperatures. At this situation, it is recommended to purchase CCT tubable color temperature of pendant lights.
