SK6812 RGBW vs tm1814 ucs2904 sm16704 ws2814A vs ws2814 addressable led strip light
2022-01-04

In the beginning, pixel led strips were mostly RGB light strips. With the continuous expansion of the addressable led strip light, RGBW is becoming more and more popular.
Currently, RGBW pixel light strips mainly include sk6812 RGBW led strip, ws2814 led strip light and ucs2904b / tm1814 / sm16704 / ws2814a led strips, but what are the differences between these light strips? Which one is better for your project? Here we will give you an answer.

Brief introduction of sk6812 rgbw led strip
sk6812 rgbw LED strip is a 5V individually rgbw addressable led strip light. The IC is embedded into the 5050 LED or 3535 led, which makes it has a better lighting performance.

Brief introduction of ucs2904b/tm1814/sm16704/ws2814a led strip
ucs2904b/tm1814/sm16704/ws2814a led strip is external ic addressable rgbw led strip light. These kinds of led strip is equipped with external ucs2904b or tm1814 or sm16704 or ws2812a ic. Each IC controls 3leds(12V) or 6leds(24V), hence, every 3leds or 6leds are cuttable as on single pixel. Because of the higher voltage, the voltage drop of them is very limited.

Brief introduction of ws2814 led strip light
The ws2814 led strip light is an updated version of ucs2904b/tm1814/sm16704/ws2814a led strip, it enjoys all the function of ucs2904b/tm1814/sm16704/ws2814a led strip. At the same time, it's a two signal pixel led strip which means the break continuous function, while one ic is broken, the signal can still pass through.
As far as we knew, this is the only type of rgbw pixel led strip with break continuous function. So, if you need higher quality pixel rgbw led strip, you can consider this.
Comparison
1. SK6812 RGBW led strip is individually addressable
Firstly, the chip of SK6812 RGBW magic light strip is built-in, which can realize single point and single control, and can achieve 144 lights 1 meter at most. (In fact, it can be regarded as an upgraded version of WS2812B, the color is upgraded from RGB to RGBW).
2. The voltage drop of SK6812 RGBW led strip is more obvious
But the disadvantage is also obvious. Its voltage can only be 5V, the voltage drop is relatively obvious, and the connection length is relatively small.

But the disadvantage is also obvious. Its voltage can only be 5V, the voltage drop is relatively obvious, and the connection length is relatively small.
3. The voltage of tm1814 sm16704 ws2814a led strip can be 5V 12V and 24v
The IC of the TM1814/SM16704/WS2814A pixel light strip is external and can be designed to be 5V, 12V and 24V, but it is rarely designed to be 5V. In the case of 12V&24V, compared to SK6812 RGBW, the voltage drop is not so obvious, and can be connected to be longer. For 12V, there are 3 lights in 1 group; for 24V, there are 6 lights in 1 group. Relatively speaking, there are fewer ICs, so the price is cheaper.
4. tm1814 sm16704 ws2814a led strip are more popular in the market
As far as our sales are concerned, more customers are willing to choose TM1814/SM16704/WS2814A pixel light strip, because the overall performance is better. Generally, a group of 6 lights or a group of 3 lights can meet most of the design requirements, and the controller cost is relatively lower.
5. ws2814 led strip is better than tm1814 sm16704 ws2814a led strip
On the basis of TM1814/SM16704/WS2814A magic light strip, there is also WS2814 RGBW magic light strip now. WS2814 IC is equivalent to the upgraded version of TM1814/SM16704/WS2814A. It has all the performance of this ordinary RGBW, plus an additional breakpoint. With the function of resuming transmission, the damage to a single IC does not affect the quality of the subsequent light strips, so the performance is more stable.

1. ucs2904b vs tm1814 vs sm16704 vs ws2814a led strip? Which one is better?
1. ucs2904b vs tm1814 vs sm16704 vs ws2814a led strip? Which one is better?
For ucs2904b, tm1814, sm16704 and ws2814a led strip, they are of same function and their out looking is also nearly same. You can't figure ou the item type unless youcheck carefully on the ic which indicates the ic module.
At the moment, ucs2904b led strip light are more popular in the market. Yet, the price is also much higher compare to tm1814, sm16704, ws2814a led strip. If you need lower cost, then you can also consider tm1814, sm16704, ws2814a. All of them are well tested and of high quality.
2. Why some tm1814 sm16704 ws2814a led strip are very cheap?
Of course, some suppliers in the market use low-quality RGBW 5050 led and imitation 3M adhesives to reduce costs, and the quality is often unstable. Therefore, before making a decision, please ensure that these raw materials are of high quality in order to ensure the stability of quality.
