Here's what you need to know about lights

Understanding the "lights" is necessary before selecting the best lighting fixture for our space.The sun is the best natural light source, and humans have been utilising it for thousands of years. The widespread belief is that the better the light, the closer it is to sunlight.

By charging fairly and being dedicated to our consumers, Cutesy Home hopes to bring gorgeous lighting into every house.


3 Parameters of Lighting

Illuminance, colour temperature, and colour rendering index are the three factors that determine if the light is suitable.



The total amount of light that strikes a surface per square inch is known as illumination. It is a measurement of how much incident light illuminates the surface, and can be used to characterise light brightness. The owner is mainly concerned with "if my home is bright enough." Using an illuminometer, the precise value can be determined.

Because the luminous efficiency of various types of lights varies widely, high power does not necessarily equate to high brightness. An 8W LED light, for instance, has the same brightness as a 40W incandescent.

Lighting levels for rooms typically range from 100 to 200 Lux for the porch, storage, bedroom, kitchen, and bathroom; from 100 to 300 Lux for the living room; and from 250 to 500 Lux for the work area.



The appearance of a light, or what we typically refer to as the "warm" or "cool" aspect of light, can be measured using colour temperature, which is represented in kelvins and denoted by the sign K.

Color temperature for light bulbs comes in three main categories: Soft White (2700K to 3000K), Warm White (3500K to 4100K), and Daylight (5000K – 6500K). The colour temperature becomes whiter as the Degrees Kelvin increase.

For instance, the Crystal Ring Chandelier uses LED light strips as its light source, which allow you to adjust the colour temperature between 3000K, 4500K, and 6000K to suit your mood.

Candlelight has a colour temperature of 1900K, incandescent lights are 2800K, fluorescent lights are 4500K, and sunshine is 5400K.

It is typically advised to use a low colour temperature for a peaceful environment and a high colour temperature for a productive one. Personal preference will define the exact colour temperature value, however the top limit in a common family is 6500K.

Index of colour renderings

A light source's capacity to accurately display the colours of distinct objects is quantified by the colour rendering index (CRI).

CRI scores are quantified as a scale of 0-100. In general, a light source renders colour more accurately the higher the CRI.

Reds, greens, and other colours will appear as such under high CRI lighting. While low CRI lighting distorts colours and significantly heightens eye strain.

CRI for the noon sun is 100. Outdoor lighting's CRI should be above 65 and indoor lighting's CRI should be above 80 for best results.

Interactions between illumination, colour temperature, and colour rendering index have been observed. Choose lights with the proper colour temperature and colour rendering index under the suitable level of illumination for the best sensory effect.

For instance, it is preferable to utilise warm white light with a colour temperature of 3000K when the lighting in a bedroom is 150 Lux; otherwise, the colour would be excessively dark or distorted.

Everyone's tolerance for light colours varies. Despite having a high enough colour rendering index, some individuals believe that light with a colour temperature of 3000K is very dim. Therefore, it is preferable to experience the light environment with various colour temperatures in the actual store before making a decision.

You have a general comprehension of the light after knowing its fundamental characteristics. We now continue.


Various Lights

Incandescent, halogen, fluorescent, energy-saving, and LED light are the main categories of artificial lighting sources. Chandeliers made by Sofary can be lit with any kind of light.



An incandescent light bulb is a type of light source that uses tungsten wire that has been heated to a high enough temperature to produce visible light (incandescence).

The continuous spectrum of incandescent light is comparable to that of sunlight, and its colour rendering index is greater than 95.

They are widely used in residential and commercial lighting and come in an incredibly wide variety of sizes, wattages, and voltages.

Incandescent bulbs typically have limited lifespans of about 1000 hours, making them far less efficient than other types of electric lighting. They only convert less than 5% of the energy they consume into visible light. Additionally, incandescent lighting's colour temperature is too low for the workspace.


In essence, halogen bulbs are incandescent bulbs with increased performance. It is more efficient because of the heat emissions, which need more energy to produce light. It can also operate for up to 2500 hours, which is a longer lifespan.



A fluorescent light is a low-pressure mercury vapour gas discharge lamp that emits visible light by fluorescence, commonly known as a low-pressure mercury lamp.

Along with the benefits of different colour temperatures and a longer lifespan of roughly 2500–3500 hours, it converts electrical energy into usable light far more effectively than an incandescent lamp.

The fluorescent's discontinuous spectrum, which has a colour rendering index of only about 85, and a start-up and stabilisation time of more than 30 seconds are disadvantages. Additionally, mercury contamination and flashing lights are issues there.



A compact fluorescent light, often known as an energy-saving light, is a fluorescent lamp created to replace out an incandescent light bulb. Similar to other fluorescent lighting, the operating principle is unchanged.

It benefits from a tiny volume, an efficient light source, and a compact structure. CFLs use one-fifth to one-third less electric power and have a longer service life of more than 6000 hours as compared to general-purpose incandescent lamps that produce the same amount of visible light.

The electronic ballast is susceptible to damage and has a low colour rendering index.



A light source that uses one or more light-emitting diodes to produce light is known as an LED (LEDs). Without any warm-up period, it may reach its maximum brightness right away.

Compared to incandescent light sources, LEDs have various benefits, such as lower energy consumption, a lifespan of over 50,000 hours, better brightness, improved physical resilience, smaller size, and quicker switching.

The low-quality LED bulb has a very low colour rendering index—even below 50—due to the uneven spectrum, making it insufficient even for outdoor use. Because of this, many LED lamps appear dazzlingly bright but have subpar illumination effects.

The current standard light source is high-quality LED lighting, which has solved colour rendering index flaws.
