What is CRI?-SPOTLIGHTING
About CRI
Many people often ask me what is LED bulb CRI and why should I choose high CRI LED bulb?
People often use lamps in their homes, but they don’t know much about the terms of lamps.So when choosing the led light, for some parameters do not require too much, but the other is very irresponsible for yourself.
Now this article will talk briefly about CRI.
First know what LED BULB CRI is!
CRI is the abbreviation of Color Rendering Index, which refers to the Color Rendering Index. The concept of CRI was introduced, and the standard light source was used to set its Color Rendering Index as 100, while the rest of the light sources had a Color Rendering Index less than 100.The color rendering index is expressed by Ra. The greater the value of Ra, the better the color rendering of the light source;Ra is the color rendering index (expressed by Ra, the greater the value of Ra, the better the color rendering of the light source).
2020 best selling indoor bulbs need to meet a CRI of 80 or above. The color rendering index (CRI) is measured as a number between 0 and 100. At zero (0), all colors look the same. A CRI of 100 shows the true colors of the object. Incandescent and halogen light sources have a CRI of 100. Typically, light sources with a CRI of 80 to 90 are viewed as a good and those with a CRI of 90+ are excellent! The general rule is: The higher the CRI, the better the color rendering capacity. No one wants to buy a light bulb with a low CRI, because it will affect the true color of the object.When choosing bulb , would rather spend a few more money, also want to buy a bit better bulb, such ability has a more comfortable living environment.
So why choose high CRI led bulb?This is why the light quality of a museum must be above CRI95, because the color rendering of a CRI95 or above can restore the purity, saturation and clarity of the color, which can truly present the exquisite details and brilliant colors of precious cultural relics and works of art.It can be easily seen by comparing the two pictures below.

What is Color Temperature ?-SPOTLIGHTING
About Color Temperature
Cold light and warm light are defined by color temperature.
Many peop don’t know whether they should select the warm white led bulb or cold white led bulb while decorating their house. I can only say each one has their one standard for the color . Personally, for the bedroom, I will choose warm light, which is conducive to sleep；for the living room ,i will choose cold white ,which is bright enough to do some actions
The color temperature exceeds 5000K time color is blue, giving a person a cold feeling, called cold light;When the color temperature is below 3000K, the light color will be red, giving a warm feeling called warm light.
Light with low color temperature is yellow, such as incandescent lamp, about 2800K, while light with high color temperature is blue, such as violet lamp, more than 9000K.
It is generally believed that the color temperature of standard white light is 6500K, and the white light emitted by CRT is about 5500K. The effect of increasing or decreasing the color temperature can be simulated by slightly changing the mixing ratio of the three primary colors. The change process of photography, camera, display and other equipment by using the principle of color temperature is called the color temperature effect.

Warm White
The color temperature of warm white is less than 3000K.It make people feel warm and relaxed.Warm white led bulbs are best choice for bedroom and living room.
-
Pure White
The color temperature of pure white is 3000K-5000K.Pure white LED bulbs are suit for study lamps.The color temperature is determined by the composition of blue light and yellow-green light. The higher the blue light component, the higher the color temperature; the lower the blue light component, the lower the color temperature. Therefore, if the color temperature is too high, the blue light content will be relatively high, and the high energy blue light will damage the retina.
-
Cool White
The color temperature of cool white led bulb is more than 5000K.Cool white LED light bulbs are best suited for office, because these places require bright light for us to work.

How to select LED light bulbs?-SPOTLIGHTING
How to select a suitable LED light bulbs? We only know that the whole world is bright when we press the switch every day. In fact,there is a lot of learning in it that deserves our careful consideration. When we are ready to buy a new light bulb, there is also a lot of learning. Now I will teach you how to choose the right LED bulbs.
- Color Temperature
The color temperature of LED light bulbs is divided into warm white, day white and cool white. 3000-3500K is warm white, 4000-4500K is day white, and 5700-6500K is cool white. If you are choosing LED light bulbs for your bedroom and living area, then it is recommended that you choose a warm white LED.This shade of LED light bulbs is similar to the skin color, so it makes people feel very warm and comfortable.The white and cool white LED light bulbs are best suited for use in the study and office, because these places require bright light for us to learn and work. In addition, it is very interesting that you can choose the color of the LED light bulbs according to your personality and furniture decoration. The warm color will make you more relaxed in the bathroom, however the cool color will give you the sense of efficiency. How to choose depends on your preference. 
- Power
When choosing a bulb, we can choose the power and quantity of the bulb according to the size of the space. Below is a reference form: 
- Lamp Size
If you are buying to replace a original bulb, be sure to look at the size of your previous lamp cap. The common type of screw head for household use is E27. E refers to the thread type, 27 is the diameter of the lamp head is about 27mm.Some lamps are E14, called the small head screw, the diameter is 14mm. The B22 is a bayonet type with a diameter of 22mm.As we all know, the bayonet type has been gradually eliminated. 
- Color rendering index
The color rendering index of the LED is the parameter of the LED light bulb’s ability to restore color. The greater the color rendering index, the better the color reproduction.For example, restaurants should choose high-color rendering index lights, which will make food more attractive. Of course, the larger the color rendering index, the more expensive the bulb will be, so you can choose different color rendering indexes according to different occasions.

Factors Affecting The Life Expectancy of LED Lights-SPOTLIGHTING
We all know that the life expectancy of LED lights is between 1-5 years.Why do the bulbs that look the same shape have different lifespans?how to select the best led light bulbs for home?
1.LED Chip
The LED chip is the core component of the LED light source, and its lifetime largely determines the life of the LED lamp. There are three factors that affect the life of LED chips: the lattice defects of the chip, the packaging process and the quality of the phosphor.it is important to choose the best led light bulbs for home.
First, the material constituting the LED chip is a crystal, an ideal crystal. If the lattice is not arranged so well, and some places are missing, this defect will affect the life of the LED chip. In addition, if the impurities doped by the LED chip are not the impurities we need, it will also affect the life of the LED light source.
Whether the LED package is reasonable or not is also an important factor affecting the life of the chip. Most companies have more imitation products of product process packaging.But the process structure and process quality are poor, which seriously affects the life of LEDs.
In addition, the performance of the LED chip has a certain degree of dispersion, before the package should be classified according to the LED chip area, light efficiency and other indicators. If the chip is not binned before packaging, the finished product yield after packaging must be uneven. That is to say, the LED package and the bin before the package are also important factors affecting the life of the LED.
The quality of the phosphor also affects the lifetime of the LED chip. At present, there are various methods for producing white light by LED chips, and two of them are white light by phosphor. One method is to coat a YAG (Yttrium Aluminum Garnet) phosphor on an LED blue chip. Since the photon with short wavelength is larger than the photon energy with longer wavelength, the blue light emitted by the chip (short wavelength) excites the phosphor to produce yellow-green light (wavelength longer than blue light) from 500 nm to 560 nm, and white light is synthesized by blue light and yellow-green light.The cost of obtaining white light by this method is relatively low, but the uniformity of the phosphor is difficult to control, and the light effect and color temperature will change correspondingly after the chip is used for a period of time.
Another method is to let the LED chip emit ultraviolet light, and the ultraviolet light then excites RGB (red&green&blue).Phosphors to generate red, green, and blue three primary colors, and the three primary colors are mixed into white light. Because the photon energy of ultraviolet light is large, resulting in the epoxy resin of the encapsulating material is easily aged, which also affects the life of the LED chip.
- The design of Heat dissipation
A reasonable design of the heat dissipation is to meet other metrics of the LED Lighting.For example, the original LED products of companies such as Cree are used on different lights,the LED life difference could be a mutiple of one to ten. Because of the contact between the light source and the heat dissipation channel does not have good heat dissipation, some products cause light decay of more than 50% after lighting for 1-3 months.Some products use a small power tube of about 0.07 W, because there is no reasonable heat dissipation mechanism, resulting in very fast light decay. These products are low in technical content, low in cost and short in life.
- Driver power
The drive power plays a key role in the life of the LED Lights. This is a problem that cannot be ignored, and it may also be the bottleneck of current LED lamps. When inspecting damaged fixtures, it is often found that the LED chip is not damaged, but the drive power supply has damaged.
- Using Environment
The using environment of LED lamps also affects the length of their life to some extent. Differences in ambient temperature, sand environment and precipitation conditions can cause differences in the service life of LED lamps.

ANASYSIS FOR THE MAIN FACTORS OF LED BULB
- Luminous Flux
Luminous Flux refers to the radiant power that can be felt by the human eye. It is equal to the radiant energy of a certain wave band in unit time multiply the relative visibility of this wave band. Since the relative visibility of the different wavelengths of light is different for our eyes, the luminous flux of the different wavelengths of light is not equal. The unit of Luminous Flux is Lumen(Lm). Led light bulb walmart best selling light should have high luminous flux to ensure the high brightness .
- Color Temperature
When the color of the light emitted by the light source is the same as the color of the black body at a certain temperature.The temperature of the black body is called the Color Temperature. The Unit of Color Temperature is Kelvin (K).Led light bulb walmart have a wide range of CCT from 2700-6500k, you can adjust it according to your current mood.
- Light Effect
The Light Effect is an important indicator for measuring the energy saving degree of a light source. It is equal to the Luminous Flux emitted by the light source divided by the power consumed by the light source.The Unit of Light Effect is Lumens / Watt (Lm / W)
- Color Rendering Index
The Color Rendering Index is the degree to which the light source is presented to the object and the degree of color fidelity.Usually called the “CRI”.The Unit of CRI is Ra.
- Illuminance
Illuminance refers to the extent to which an object is illuminated. It is equal to the ratio of the luminous flux obtained by the surface of the object to the illuminated area.The Unit of illuminance is Lux/lx（1 lux is the illuminance produced by a uniform luminous flux of 1 lumen on an area of 1 square meter）
- Power Factor
In the AC circuit, the cosine of the phase difference (Φ) between voltage and current is called power factor and is represented by the symbol cosΦ. In term of value, the power factor is the ratio of active power(P) to apparent power(S). The formula is cosΦ=P/S.
Power factor is a factor that measures the efficiency of electrical equipment. The low power factor indicates that the reactive power of the circuit for alternating magnetic field conversion is large, thereby reducing the utilization rate of the device and increasing the power loss of the line.
- Power
The power of the LED Lighting is equal to the work done by the current in unit time.It is a physical quantity used to indicate the speed of electric energy consumption. It is represented by “P”. The Unit of Power is Watt(W).

In the context of the current global energy shortages, the energy conservation is an important issue for us in the future.At the same time,LED lighting trends is attracting the attention of the world. LED is a new type of green light source. It is bound to be the trend of future development. In the 21st century, it will enter the era of new lighting sources represented by LED.
LED is considered to be the fourth generation of illumination source or green light source. It has the characteristics of energy saving, environmental protection, long life and small size. It can be widely used in various fields such as indication, display, decoration, backlight, general illumination and urban night scene. In recent years, some economically developed countries in the world have launched a fierce technical competition around the development of LED. LED lighting has been valued by various countries for its energy saving and environmental protection advantages. Various localities have introduced relevant policies and measures to accelerate the development of LED lamps.
From a global perspective, the LED industry is in a period of steady development. At present, the global LED industry can be divided into four regions. First, the European and American regions, with general lighting as the main direction, the product features high reliability and high brightness. Second, Japan is leading the way in general lighting and backlight display, and takes into account general lighting, automobiles, mobile phones and televisions. The third is Taiwan and South Korea, with backlight display as the main line, including mobile phones, TV, computer backlights, large shipments but low gross margin. The fourth is mainland China, whose main business is outdoor display, advertising screens and lighting.The main growth of the global LED market to maintain rapid growth is the explosive growth of indoor general lighting, architectural lighting, landscape lighting, backlights and outdoor LED large screens, in the next 3-5 years, with the maturity of technology and cost As the decline, LED penetration in the general lighting market will further increase, and the continued expansion of automotive lighting, small-pitch LED display and other applications is expected to usher in a new round of LED industry explosion.
