50pcs WS2811 Dream Color Changing RGB Addressable LED Pixel String Light Waterproof 12mm DC12V for Christmas Party Advertising Board Decoration (DC12V 50pcs)

I bought these specifically to replace bad TM1804 LED's.I acquired several old pixel strings that were used on a mega tree for 10 years (2012-2022). Most still work fine. These WS2811 pixels will be cut into individual LED's and spliced in place of the few bad one's.I just received these this evening and have replaced a few and the seemed look identical to the original one's; specially full on white.Edit: It turns out that I needed an RGB control order and these are BGR; Red and Blue are swapped. They're still a good product and I'll use the them for other strings but not for what I needed.

I ordered the 50quantity 5v lights. The bag I received said they were DC12v 50pcs but I tried them out anyway using a 5v Arduino and they lit up just fine with the standard Adafruit Neopixel library. The pixel ends seem solidly made. My application needs the lights close together but those with larger spacing needs should be told that the lights are only about 3" apart and won't stretch. Anyway, happy with my purchase. I will be buying more.

Certainly not the brightest LEDs, but I guess that's not the goal since they are diffused and all. Seem well made and look waterproof.My data input stream was actually on the opposite side. It was on the female plug and opposite from the tag indication. Also, mine worked with 800KHZ bitstream GRB, which I thought was WS2812 not WS2811, not check that if yours are not working.

Great product. No issues

Lights work fine quality is good but I can get them for $7 on Ali express

I have purchased a few 1000's of these pixels. I've bought them in both the 500 count and the 50 count packages. While the color of the wire may not be the same between the two quantities, it will either be the Red/White/Green or the Red/White/Blue. This is the only difference between the two and does not affect the performance. My longest consecutive run of pixels is 178 nodes and do not have a need for power injection. The fit and finish is very good and is on par with all the other pixel manufactures.

Lights are well worth the money. Well built

You'll need an external power supply to power the leds much the same as you would with an arduino. Apparently, there are files that can be created and stored and played on a loop but I don't know what the files should look like or what the code should be. I bet this thing is really slick if you know how it works.
