With the development of using electricity, many kinds of lighting devices have been created and used widely all around the world, including LED lights. These innovative inventions are extremely popular thanks to their special features, the amount of energy provided, the affordable prices, their wide range of applications or also because they help us to save our bills in the long run.
Among many famous types of LEDs, RGB and RGBW are not exceptions. Therefore, the question about how RGB vs RGBW different from each other has appeared.
When we mention LED lights, it would be an omission unless we bring RGB and RBW into discussion, known as the primary colors mixing. These two kinds of light colors and their differences have been a widely discussed topic around the world. If you are about to find out how they different, this article will help you to figure out the answer.
The Meaning Of RGB – Red Green Blue
RGB, which stands for red green blue. This is the collaboration of these three light colors in order to create the new colors. Red, green and blue, which are three basic optical colors, the mixing of them will be a criterion method which serves for creating color images of electronic devices such as computer screens, televisions, smartphones, etc.
Additive model is a term which refers to the RGB color model. Once the mixing of every single color of brightness has occurred, there will be the production of white light. While the black light seems not to be manifested unless the creation of light is nowhere to be seen.
RBG’s operating principle is summarized as the following paragraph:
First, RED for the intensity of red color. Once the intensity of the red components reaches the maximum threshold and vice versa with blue and green, the pure red is what you get.
Next, GREEN for the intensity of green color. Once the intensity of red and blue components are at the lowest intensity, while it reaches the highest level with the color of green, the pure green is what you will get.
Last, BLUE for the intensity of blue color. Just like other colors, which will be at the lowest intensity while the blue color’s intensity will dominate. Therefore, you will get pure blue.
The Meaning Of RGBW – Red Green Blue White
RGBW stands for four colors: red, green, blue, white. RGBW’s description and of RGB are quite alike in many perspectives. What makes these two kinds of lighting technologies different is the presence of white light. Thanks to the combination of three optic basic colors mentioned above in an equal proportion, the RBG’s white light producing process has been conducted. However, the white light created will be filtered by the color filter.
That will lead to the fact that the white light color created by the RGB model will not be brighter than the one which was produced by RGBW when the white light color adding process is completed. Therefore, there will be an extra presence of warm white diodes for RGBW LED light strips compared to RGB ones. According to the Kelvin scale, which is at the temperature of 2700k, the warm white diode appears a slightly yellow tone, making the cozy atmosphere for spaces. It is recommended that spaces like living rooms, dining rooms, etc are the perfect options for using RGBW LED lights .
The problem of compatibility between the indoor light color temperature and the interior decoration’s basic color should be taken into consideration. The best color temperature used for LED lights at your house depends on many crucial factors such as the grounds, walls, furniture or the rooms’ use, in other words the functions of those rooms. Generally, you should pay close attention to these factors. In order to benefit the elderly and children, we recommend you to use LED lights with low–color temperature as much as you can.
Spaces like offices or schools are suitable for using bright white LEDs, while warm LED lights are the good choices for rooms at home such as bedrooms, living rooms as mentioned previously. So, the appropriate light color temperature for our vision is the traditional colors calculated by the Kelvin scale with a range of 2700k to 5700k.
RGB Vs RGBW – How To Distinguish ?
These two kinds of lighting technologies are not only different because of the appearance of white light, they are also not alike due to many other factors, which we are going to discuss in the next paragraphs.
For that being said, three basic colors in RGB lighting systems are red, green and blue. While the similarity in mixing work and the additional presence of white light helped create RGBW LED lights. The collaboration of these three primary colors and the extra white chip will produce the exact colors and those colors will be more colorful.
The CR Index
CR Index stands for color rendering index. In comparison with RGB LED lights, RGBW lighting will have a higher CR index. For this proof, RGBW LEDs are able to reproduce the initial colors of the objects more accurately. In general, the exact color replication will be demonstrated when we bring RGBW LED lights into operation.
Full-Spectrum Lighting Capability
Once again, RGBW lights overcomed RGB LEDs in the full-spectrum lighting capability competition. Thanks to the additional white light, RGBW LED lights are able to show types and accurate colors with a higher quantity. This will result in full – color lighting achievement of RGBW LEDs.
A RGBW LED light strip has more pins than a RGB LED light strip does. While a RGBW LED strip has 5 feet, the number of feet that a RGB LED strip does have is just 4. One more sign which shows us RGB LED strips and RGBW LED strips are non-identical is their shapes of feet when we can see the fifth feet of RGBW light strips create the “W”. This will help the identification become easier.
With the extra appearance of white light, RGBW LED lights seem to be brighter than RGB LEDs, they transmit a higher level of brightness and the most important is that they are energy-savings, this will have a positive influence on our lives and our planet.
Applications Of RGB & RGBW
The applications of these two types of lighting systems play an essential role that help your choices be more appropriate. For instance, RGB LED light is an ideal lighting method. Without any additional work, RGB LED lights are widely used for recording or photography purposes. Because RGBW lighting is capable of replicating the better colors and giving more colors mixing choices, which is usually taken advantage of in entertaining, gaming, commercial spaces like shopping malls or resting places, etc. Choosing RGB LEDs or RGBW will also depend on the specific demands of the applications, the colors performance or your own preferences.
For anyone who wants to control LED light fixtures more proactively, RGBW LED light strips with a 4-in-1 chip should be taken into consideration. This product is three optic basic colors and an extra white combined. Despite the fact that these models are quite more expensive than others, if you want your LED light strips to emit higher levels of illumination, you should invest in these lighting systems without any hesitation. By utilizing the controllers, RGBWs and RGBs as well, the conversion from this color to others will be conducted.
For that being said, RGBW LED lights with the extra white light are able to emit the brighter light, they can also provide more pure white light thanks to that additional factor. Not only white diodes, there are also many other types of additional diodes which depends on the colors of those extra diodes, such as RGBNW stands for the mixing of RGB (three optic basic colors: red, green, blue) and neutral white or we have RGBWW, combined with RGB and warm white.
RGBW LED lights are widely used at places which need the precision lighting conditions such as supermarkets or resting places, just like mentioned earlier. If you are looking for lighting devices which serve for decorating and displaying purposes, RGB is sufficient. While you are working at places where concentration and productivity is priority, lighting devices providing bright white color should be utilized and RGBW LED light is the most recommended solution.
Like we mentioned before, RGBW LED light provides a higher level of brightness compared to its predecessor RGB and RGBW LED light is energy – savings too. Moreover, it is indicated that the RGBW LED is complex right from the production line when it needs to go through many processes and censorship. This is a huge innovation of lighting technology and naturally, quality always comes with price and this is true for RGBWs. Therefore, the price of a RGB LED light is obviously lower than the other product.
RGB Vs RGBW – Who Is The Winner ?
Compared to RGB LED lights, RGBW LEDs are dominant. With an extra white LED chip, this kind of lighting device will increase the brightness quality. Not only that, it is able to emit the light more effectively without wasting too much power. The flexibility of RGBW LED lights also received a special consideration. With the situation of climates changing erratically, flexible lighting technology is extremely indispensable.
Here are some advantages of RGBW LEDs, which will prove why this kind of LED light is better than RGB.
Their High Quality
The white light created by RGB LED lights is the collaboration of RGBs themselves and basic photons. But the white light produced will not be more realistic than RGBW LED lights due to the conduction of color diffusing and blending and the light color has high saturation. This light color is considered to be foggy, which can cause people discomfort when the foggy light affects our vision. In the meantime, RGBW LED lights emit the white which is filtered well, cleaner and light color saturation is way lower. This will make us have good experiences when we see realistic white light with our naked eyes.
Not only that, the flexibility of mixing the colors and the supplication of a larger spectrum of distinct hues are noticed thanks to RGBW LEDs with the presence of an extra white light.
Energy – Savings
RGBW LED lights emit high levels of brightness and only with a low quantity of them, you will have your places surrounded by the huge illumination without any concern about wasting energy. While RGB LEDs provide a lower level of brightness, so the amount of products needed is way much more which will lead to the increasing of energy used and it will make your purchase invoices appear with many digits.
Better Lighting Efficiency
RGBW LED lights provide the illumination more effectively, this results from the high capability of transmitting the light. Different from the ability to absorb and mix light of RGBs, RGBW LEDs will make lighting efficiency rise significantly by reverberating the shine without wasting it. RGBW LEDs emit the light with a higher level although they spend the similar amount of power as RGB LEDs do.
The Comparison Of RGB & RGBW Light Strips
A wide range of adjustable colors is noticed thanks to the originality that RGB LED light strips have and it allows you to turn those strips into any shape as your preference. Once again, we mention the appearance of an extra white light chip when its presence facilitates the greater color variation and the white light produced will be “quite over”.
Why Is An Extra White Chip Needed? The available white color in a LED strip will give us plenty of options when we can decide whether our LED light color is warmer or cooler. This will also flexibly adapt to today’s climate change. Not only that, the diversity in color mixing is seen clearly.
How to choose appropriately? In case you want your space to be decorated by the lighting condition which is simple, primary and has no pure white light, RGB LED light will be a good option for you and your place. Moreover, you will be able to save your budget when this lighting product is not too expensive.
Unless you don’t want your home surrounded by the lighting system with a greater color rendering index and plenty of choices about color and shine, RGBW LED light will be perfect. Despite its cost, your LED light can save a significant amount of power. Not only that, you will be able to adjust the device’s color and brightness more proactively.
These two kinds of lighting devices are obviously famous for their features, their high efficiency and their applications. Their positive influence on our lives and our planet is not much disccused. We hope in this article, you will be able to gather more comprehension about the meanings and the differences of RGB Vs RGBW LED light.
