The difference between RGB and RGBW LED

RGB and RGBW is a couple of words that we commonly see and hear in the LED lighting industry. Today we are gonna review the RGB LED and RGBW LED, and find their difference.

RGB and RGBW LED Strip Lights

Combin 3 diodes (red, green, and blue) in 1 SMD chip, the RGB LED can realize color changing. To achieve better white light, adding a white light diode on the RGB LED, that's we call RGBW LED. So, RGBW is an RGB LED with an additional white light diode (the packaging process is far more complicated).

Through the controller, RGB and RGBW LEDs can switch from different colors, such as white, red, green, blue, pink, yellow, cyan, and so on. However, having an extra white light diode make the RGBW LED has a brighter and more pure white light performance. And according to the additional diode's color, there are also have RGBWW (RGB+ warm white), RGBCW (RGB+ cool white), and RGBNW (RGB+ neutral white), which can give you more choice.

To further introduce the difference between RGB and RGBW LEDs, we'd like to take the LED strips for example. The RGBW LED strip has 4 independent control circuits, and the RGB LED strip has 3. Therefore, we can visually note that the RGBW remote is more complicated than the RGB remote, and has more functions. From the connector, we can easier distinguish RGBW LED strip (5 pins) and RGB LED strip (4 pins).

Now, we learned that compared to the RGB LED, the RGBW LED has better white light performance, more color choices, and more functions. So can we conclude that the RGBW LED is better for buy? No, there is another important factor that we haven't take into account. As mentioned at the end of the second paragraph, the processes of RGBW LEDs are far more complicated than that of RGB LEDs. And the complex processes make the cost increase to the price. In today's market, the RGBW LED is several times more expensive than the RGB LED. To sum it up, RGBW LED lights are the better choice if you or your customers are strict in the white light performance and have enough budget. Opposite, if you just want to make rooms or restaurants more colorful, the RGB LED light can meet your satisfaction, and more cost-effective.

How to install LED strip and power supply

LED strip, also known as led tape light, is one of the most popular linear decorative lighting fixtures for homes, shops, supermarkets, hotels, etc. Due to most of the LED strips' input voltage is 12V DC or 24V DC, they can't be directly connected to the 110V AC or 220V AC. So we need a power supply to transfer the high voltage AC to low voltage DC. Now let's see how to install LED strip and power supply.

Please note that the power must be cut off before installation to avoid the risk of electric shock.

1. Power supply wiring

Here is a typical power supply which inputs 100V to 220V AC and outputs 12V DC. As you can see from the picture below, the first and second interfaces are the high voltage input, and the third interface is the ground electrode. The first step is to connect the power cord to the input ends and tighten them with the screwdriver.

Install Power Supply

 2. LED strip wiring
In general, the red wire is the anode of the LED strip and the black wire is the cathode, which should be connected to V+ and V- of the output ends of power supply accordingly. The colors of the wires of the LED strip may be different from the different models or suppliers.

Install LED Light Strip

Power on, the LED strip will be lit up. If the LED strip does not work, it may be the wires are reversed, we can reverse two wires of the LED strip and try again.

Lit Up

Above is the simple installation and connection of the regular single-color LED strip light and power supply.

Shenzhen Mailederun Technology Co., Ltd. (MLDR®) is a professional LED strip lights manufacturer in China, supplying all kinds of LED strips and accessories.

LED lighting, the new growth point of plant factory

In Shizuoka Prefecture, Japan, a large plant factory, which has been operating since 2014, covers an area of ​​about 5,000 square meters and produces four salad vegetables.

Katashi Kai, general manager of the factory's operations department, said that the biggest advantage of using LED grow lights is that they can guarantee stable production and supply throughout the year, independent of climate and environment. The cultivation management and hygiene control methods completely eliminate dust, insect pests, and foreign matter pollution, and can produce high quality and safe vegetables without using pesticides.

In the early days of its establishment, the factory used traditional fluorescent lamps as the light sources. But the fluorescent lamps have various problems. For example, the heat generated by fluorescent lamps can burn plant leaves, and the fluorescent light has a short decay period, and the fluorescent lamps have a risk of causing pollution of foreign matter. Kai said: "LED lights do not have such problems or risks. Therefore, we decided to replace the fluorescent lamps with LED plant grow lights, in the medium and long-term operation, the use of LED lighting can greatly reduce operating costs."

The LED lights were fully utilized in the factory in 2017. Compared to the previous, the electricity cost of the factory was reduced by about 40%, and the growth rate of vegetables was increased by 20% to 30%. Higher growth rates mean higher yields in the facility, lower production costs, and no change in the taste and nutrient content of the vegetables.

LED Strip Backlight for advertising fabric light boxes

Ultra-thin advertising light boxes

Backlight LED light strip is designed as the backlit light source for thin advertising light boxes with a thickness of 3 to 15cm. MLDR®, a China's lighting company, introduced the MFS3030 series of LED backlit strip in 2017. After years of development, there are a variety of specifications of MFS3030 backlit LED strip lights, such as input voltage (12V and 24V DC) and colors (cool white, white, warm white, red, green, blue, etc.).

Fabric ceiling

MFS3030 series LED strip lights are made of high thermal conductivity PCB, high bright SMD 3030 LED, and the high transparent lenses. Thanks to its ultra-wide beam angle of 175 degrees, the MFS3030 backlight strips are able to achieve better light efficiency than conventional LED strips in fewer numbers in ultra-thin light boxes. Without a doubt, the cost of the project will decrease as the number of LED strips is reduced. With the increasing demand for outdoor advertising light boxes, the IP65 waterproof LED strip backlight come into being.

Not only in the field of the backlit lightbox, but MFS3030 LED strip backlight is also used in the fabric ceilings, fake windows, signboards and so on.

What do the numbers of LED mean? such as 2835, 3528, 5630, 5050, and so on.

If you've ever bought or read about LED strip lights, you've probably been impressed by these numbers (models), 2835, 3825, 5630, 5050, etc. Actually, the meaning of these numbers is very simple.

Fundamentally, all of these numbers are the models of SMD (Surface Mounted Diode) LEDs, representing their sizes. Take SMD 2835 LED as an example, 2835 means its length and the width of the LED is 2.8mm and 3.5mm. SMD LED is a kind of semiconductor light source that directly mounted on the LED light strip, having characteristics of high brightness, low power consumption, and good workability.

Normally, the larger the sizes of the SMD LED, the higher the lumens and the better the heat dissipation. But, there also have exceptions. Let's compare the RU5050 LED strip and RU5630 LED strip these two LED flexible strip lights. Obviously, the RU5050's SMD 5050 LED light source is larger than the SMD 5630 LED of RU5630. However, in fact, the RU5630's brightness is higher than that of the RU5050, that is caused by the 5630's chip size is relatively bigger. But SMD 5050 LED has more excellent heat dissipation performance, which makes the LED light strip working more stable. Even the brightness of the same model of SMD LEDs may not be the same, which involves the materials, processes, and rated power.

You should know the meaning of these number of LED strip lights and their main differences by now. MLDR® is a professional LED light strip manufacturer in China, aiming to provide reliable LED lighting products to customers all over the world.
