TM1814 RGBW addressable LED strip is flexible LED strip light similar to UCS2904. The externally installed IC can drive the LEDs on the strip to display kinds of effects. It contains RGBW LEDs (Red, Green, Blue, and White) that can emit any color in the visible spectrum. These LED strips are digitally addressable, allowing you to control the color and brightness of every 3 or 6 LEDs with a controller.
It is usually a 5 meters long strip that is equipped with 60 pcs RGBW LEDs per meter. It uses a unique coding system and each segment of LEDs can be programmed. Create intricate lighting designs with ease.
Compared to the SK6812 RGBW, the TM1814 uses an external IC, with every three or six LEDs on the LED strip acting as a control unit. Operating voltages are 12V/24V. Each reel contains 50/100 IC chips.
Among addressable RGBW LED strips, dual-signal RGBW ICs offer more stable signal transmission than single-signal ICs. If one signal line is interrupted, the other backup line automatically resumes operation, significantly improving system reliability in large-scale pixel matrix projects.

RGBW Addressable LED IC Comparison
When choosing an RGBW addressable LED strip, the driver IC determines performance, stability, and color quality. Popular
options such as WS2814, TM1814, UCS2904, and UCS7604 are all external ICs for RGBW pixel control, but each has unique strengths.
WS2814 is widely used in cost-effective projects thanks to its reliable design. TM1814 improves current accuracy
(±3% channel consistency) and integrates a 5 V regulator for stable 6–24 V operation. For higher-end displays, UCS2904 offers enhanced
anti-interference and 12-bit grayscale for smoother dimming. At the top of the range, UCS7604 delivers 16-bit grayscale (65,536 levels),
a 16K refresh rate, and dual-signal redundancy with breakpoint-continue, making it flicker-free under cameras and robust for long runs.

Addressable LED strips have become increasingly popular in recent years due to their versatility and ability to create stunning lighting effects. The TM1814 and SK6812 are two addressable LED strip options that are commonly used in a variety of lighting applications. While they may appear similar, they have some key differences that should be considered before making a purchase.
Here is a comparison of the technical specifications of the TM1814 RGBW LED strip and the SK6812 RGBW LED strip:
| Specification | TM1814 RGBW LED Strip | SK6812 RGBW LED Strip |
| LED Type | RGBW 5050 SMD LED | RGBW 5050 SMD LED |
| LED Density | 60 LEDs/meter | 60 LEDs/meter,144 LEDs/meter |
| Voltage | DC12V, DC24V | DC5V |
| Power Consumption | 19.2W/meter | 19.2W/meter, 43W/meter, |
| IC Type | External IC | Built-in IC |
| Pixel Quantity | 20 pixels/meter, 10 pixels/meter | 60 pixels/meter, 144 pixels/meter |
| Color | RGB color mixing, plus white | RGB color mixing, plus white |
| Dimmable | Yes | Yes |
| Cuttable | Yes, every 3 or 6 LEDs | Yes, every LED |
From the above table, we can see that the TM1814 and SK6812 are both SMD5050 RGBW LED, and they both have 60 LEDs/m versions. The key difference is the TM1814 strip has an external IC, but the SK6812 strip has a built-in IC, this means the TM1814 LED strip doesn’t have an individual control function, it can be controlled and can be cut every 3 or 6 LED segments. The voltage is also different, TM1814 can be DC12V and DC24V, but the SK6812 LED strip can only be driven under DC5V power. From the perspective of the LED density, the TM1814 doesn’t have the 144LEDs/m version.
In conclusion, if you don’t pursue individual control and need a wider voltage range, the TM1814 is a better choice, and it can help you to save costs. However, if you want a brighter lighting effect and require individual control, the 144LEDs/m SK6812 LED strip is your perfect choice. So the choice between the TM1814 and SK6812 LED strips will depend on the specific needs of your project. For more details about how to choose TM1814 vs SK6812, please click here.
