Answer: WS2811 is 12V. Single channel 60 LEDs is 14.4 watts. While, WS2812B is 5V. Single channel 60 LEDs is 18 watts.


4. Can I connect WS2801, WS2811 and WS2812 LED light strips together?

Answer: You might try connecting different LED strips to each other, provided they have the same voltage. If you try to connect two or more strips with different voltages, they won't work at all and will be damaged. It's a waste of money and better not to do it.


5. Do WS2811 or WS2812b LED strip lights overheat?

Answer: Smart LED strips rarely burn out if you connect the strips correctly. However, if you have too many strips connected in series, you can overload the circuit. Because the total resistance will be too high, generating too much heat.


6. Is WS2812B LED strip RGB or RGBW?

Answer: Typically, WS2812b is RGB only. Sometimes advertising though advertises something as WS2812b, even though it's actually not. Because most people won't search for SK6812, but WS2812b because it's more popular. But this kind of error message is usually not a big deal because the SK6812 has the same protocol as the WS2812b. For addressable LED strips, WS2812B and SK6812 are generally considered to be the most commonly used.

The SK6812 RGBW LED strip is the latest upgraded version of the WS2812B LED strip. R/G/B/W 4 colors in 1 LED. SK6812 has richer color variation and color combination possibilities. Has all the features of the WS2812B LED strip.


7. How do I adjust the color of the WS2811 or WS2812b LED strip light?

Answer: You usually have the following options. (1) Dimmer and controller with remote control (2) In-line dimmer and controller (3) Knob dimmer for monochrome LED strips. The Monochrome controller lets you change the color, mode, speed or brightness of the strip. Monochrome dimmers let you adjust just the brightness of the strip.


8. How do I connect my WS2811 LED strip to the boat's power supply?

Answer: You can power the boat's WS2811 LED strip by connecting to the boat's 12V battery. Make sure your marine battery's power supply is compatible with the voltage of the WS2811 LED strip.


9. How can I prevent my WS2801, WS2811 or WS2812 LED strip from falling off?

Answer: Start by cleaning any dust, water, moisture, grease, or other things from the surface the LED strip will be mounted to. Cleaners such as methylated spirits or rubbing alcohol may help, but allow time to dry. You need to use a dry, lint-free cloth to properly clean the surface.


10. How to re-stick WS2801 or WS2812 LED strip with 3M adhesive backing?

Answer: To re-remove and stick the WS2812 light bar, first cut off the power and unplug the light bar. Then use a hair dryer to heat the adhesive.

11. Can the WS2811 LED strip be reused?

Answer: If the LED strip still works, it's always a good idea to reuse it as you'll get more out of your purchase. If the 3M adhesive on the back fails, it may be a good choice to replace it with double-sided adhesive.


12. Will LED strips damage the walls in my interior?

Answer: A properly installed LED strip is generally unlikely to damage a wall, but it depends on a variety of factors. The degree to which the LED strip adheres to the surface is affected by a number of factors. Common considerations include adhesive strength, paint or wallpaper durability, age of use, and climate humidity, to name a few.


13. Can I use the WS2811 and WS2812b LED strips to grow plants?

Answer: Yes, of course you can. LED light strips help indoor plants grow and develop, and it is convenient to control the light color changes of plants.


14. What is the 5050RGB mentioned in WS2811 or WS2812B strip?

Answer: The 5050 is an RGB strip with a chip size of 5.0mm x 5.0mm. They have 3 LED diodes in each housing, called a tri-chip, and when turned on at full power, they emit a very bright glare.


15. Where is the best positon to place LED strips in my house?

Answer: Maybe you can consider the following places. under the cupboard. under the shelf. under the bed. behind computer and TV screens.


16. Can I leave the LED strip on all night?

Answer: Yes, you can keep the LED strip on all night. LED strips generate far less heat than old incandescent bulbs, so you can keep them going overnight. No need to worry about exploding or starting a fire. Also worry about damage if you forget to close it.


17. Which is the Best LED Strip brand?

Answer: Usually famous brands are Philips, Wyze, Corsair ,Govee , Maxonar... If your budget is limited, you can continue our SuntechLED. We will provide you with the best price, the best quality, and the most reasonable arrangement.


18. How do I know what type my LED strip is?

Answer: An LED strip description usually includes a 4-digit number, such as 5050 or 2835. This number usually defines the size of the chip. For example, a 5050 LED chip measures 5.0mm wide x 5.0mm high. Likewise, the 2835 chip measures 2.8mm wide x 3.5mm high.


19. Do ws2812b need resistors?

Answer: 5V high current power supply is OK for WS2812B LED strip. There is no current limiting resistor.


20. How bright is ws2812?

Answer: Both LEDs draw about 60mA at maximum brightness, so power supplies used for WS2812B set-ups are interchangeable. Of course, the number of LEDs on the strip varies and the power required is different.


21.What protocol does the WS2812 use?

Answer: Typically, users will choose WS2813 or higher for higher quality, but WS2812 is still one of the most common protocols for pixel-lit displays. Control circuitry and LEDs are integrated in a 5050 SMD package, providing a small physical size per pixel.


22. Why is my WS2801 light bar flickering?

Answer: Probably due to unstable voltage. Not only WS2801, WS2811 and WS2812 also flicker due to voltage fluctuations. Therefore, you need to have a constant voltage power supply. If the voltage drops for any reason, the entire strip will flicker and the brightness will decrease.


23. What should I do if my LED strip is blinking?

Answer: Make sure the cables from the power supply to the LED strips are connected correctly and are not missing. You might also consider soldering the connections in place so they don't move around.


24. How do I determine if a WS2812 LED strip is good?

Answer: It depends on what you're after. If you're after brighter output and higher light quality, you should look for strip lights with the highest number of LEDs per foot (meters, yards, etc.). If the LEDs are spaced too far apart on the strip, they can produce speckled lighting instead of a clean, constant light. Whether it is WS2801, WS2811 or WS2812B, choose the solution that best suits you according to your purpose and budget.


25.Why is my LED blinking red?

Answer: The most common cause of LED light flickering is a poorly matched LED power supply, also known as an LED driver. LED lights either require constant current LED drivers or constant voltage LED drivers.


26. Do I need an LED strip controller?

Answer: RGB Controller (WiFi/Remote/Bluetooth) - If you have a color changing RGB LED strip then you will need a 3 channel RGB controller. These controllers control the red, green, and blue channels to mix colors and create a color-shifting effect of the strips.


27. Is there a difference between the maximum voltage of WS2812 and WS2812B?

Answer: Both are approximately between 3.3V and 5V. The WS2812 should work anywhere between about 4V and 7V, while the WS2812B should work anywhere between about 3.3V and 5V. 5V is available on most boards. For example, the 5V header on the Arduino board is the perfect voltage supply for LEDs.


28. How many amps does a WS2812B use?

Answer: The supply we need must be 5 volts, however the shape and amperage they provide can vary greatly. Barrel jack connectors are necessary for Wall wrats (typically 0.5-2 amp)  and power brick (typically 1-10 amp) supplies.


29. How do I power my long WS2812B LED strip?

Answer: The LED strip should be powered with a 5V power supply. At 5V, each LED consumes about 50mA when set to full brightness. This means that for every 30 LEDs, the strip may draw up to 1.5 A. Make sure to choose a power supply that matches your strip's needs.


30. How about WS2801, WS2811 and WS2812B LED strip prices?

Answer: When buying LED strips individually, your cost can range from $20.00 to $50.00 depending on color, length, etc. For more detailed quotation please contact us.
