What Exactly Is Dual White LED Tape Light

Dual-white LED tape light, as its name implies, is a light strip that has two color temperatures. There are 2 different color LEDs on the PCB (print circuit board), and 2 independent circuits that are connected to different colored LEDs. So that you can switch the light's color and adapt their brightness separately. The picture below is the dual white LED tape light with a product number of R2835-SSW120, we can see that it's made of warm white and white SMD 2835 LEDs. In addition to these 2 colors, it can as well as provide daylight (4000 Kelvin) by the composition of warm white and white. Having 3 color temperature options, the dual white LED strip can improve the flexibility of both residential and commercial lighting.

1. The methods to realize dual white/ dual color
Generally, there are two kinds of methods to achieve dual color in an LED strip. The first one is mounting 2 different color LEDs on a PCB (the 2835 dual white LED strip above is a typical example). The next one is using the 2-in-1 dual-color SMD LEDs. This kind of SMD LED has 2 colors.

2. Dual-white and RGB, which is better
I have to say that there is no fixed answer to this question. They are two products designed for different applications. RGB LED strips can realize more colors, while the dual white LED strip's white light is purer and has higher brightness. Therefore, if you want to decorate your home with comfortable light, you should take the dual white LED strip into consideration. And if you want to add some dynamic to your home, the RGB LED strip will be more suitable.

3. How to install the dual white LED tape light
Like other low voltage LED strips, the dual white LED strip needs to be driven by the AC-DC power supply. To achieve color changing, dimming, and dynamic effects, a dual white controller is requested to install between the light and power supply. Most dual-color LED strips are 3 pins (1 positive pole and 2 negative poles) or 4 pins (2 positive poles and 2 negative poles), and they are a little different in the wiring.

To summarize, dual-white LED strips can provide pure white lights and more CCT options. It's widely used in residences, hotels, signages, mirrors, and so on.
