Rextin WS2811 Pixels Digital Addressable LED String Lights Waterproof RGB Full Color 12mm DC 12V (DC12V 500pcs)

Good product for a good price.... This is for the strand operated with 5 vd Setup: a 5vd/3 amp wallwort to power the strip , an UNO and both the Neopixel & fastled libraries in several sketches They functioned without any problems . Fastled - #define LED_TYPE WS2812B or as WS2811( both worked with this strip) #define COLOR_ORDER GRB - correct for this strip #define NUM_LEDS 50 Neopixel- They would not work when set to 400 KHz or RGB . // Parameter 1 = number of pixels in strip // Parameter 2 = pin number (most are valid) // Parameter 3 = pixel type flags, add together as needed: // NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs) // NEO_KHZ400 400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers) // NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products) // NEO_RGB Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2) Adafruit_NeoPixel strip = Adafruit_NeoPixel(50, PIN, NEO_GRB + NEO_KHZ800); - correct settings for this step Attached to the Ws8211 strip (50 pixel) is a WS2812B Strip (30 pixel)

Great Product, can be used with both Adafruit Neopixel library as well as Fast Led open source pixel library. Tip, Fast LED has a nice Calibrate sketch for Arduino which will help you determine the RGB order of these as well as other Pixel LED Strips. Spoiler: In my case the RGB order was as follows for my purchase RGB Order = BGR Along with NEO_KHZ800 if using Adafruit's library !!!!! ALSO VERY IMPORTANT STEP !!!!!! WHEN USING WITH AN EXTERNAL POWER SUPPLY AND ARDUINO DO NOT FORGET TO CONNECT THE GROUND OF THE PIXEL STRIP BACK TO THE ARDUINO'S GROUND PIN. IF YOU DO NOT DO THIS STEP THE COLORS WILL BE RANDOM AND YOU WILL BE LEFT FRUSTRATED FOR SOME TIME. I SCRATCH MY HEAD FOR HOURS AS MANY ONLINE NEOPIXEL TUTORIALS DID NOT MENTION THIS STEP. ALSO, ME BEING AN ELECTRONICS NOOBLET IT WAS NOT CLEAR AND SO I ONLY CONNECTED THE PIXEL DATA IN TO THE ARDUINO PIN AND CONNECTED THE POWER LINES TO AN EXTERNAL 12V POWER SUPPLY. THE ONLINE TUTORIALS LEAVE THIS STEP OUT PROBABLY BECAUSE THEY ARE TYPICALLY 5V TUTORIALS WHICH ARDUINO CAN HANDLE. SO NATURALLY ONE WOULD CONNECT THE PIXEL'S GROUND BACK TO THE ARDUINO'S GROUND PIN. HOWEVER, IF PURCHASING THE 12V STRIP YOU WILL NEED AN EXTERNAL POWER SUPPLY AND THUS THIS IS LEFT OUT OF MOST TUTORIALS I CAME ACCROSS. !!!!!!! I HOPE THIS HLEPS SOMEONE AS I STRUGGLED FOR SOME TIME FIGURING THIS OUT.

Very good leds, bright and colorfull. Love it.

Great quality for the price. Well made pixels. I’ve had another brand at a similar price that had lower quality on the casing and the pixels were often not pointing straight. Rextin brand are made as though there is care put into the making of them. I am very happy. I use them for my holiday (Halloween and Christmas) Light shows. So, in this case, a matrix display (signage) and the outlines to the windows at my house. Also, I drilled some holes in 2 x 4 to light up a cross I made to hang on my chimney. The lights in the matrix and window outlines have been actively working nightly for October and working great. The lights in the cross will be tested soon and will mostly be used for the Christmas light show. The included video is the lights operating during a programmed sequence. They are doing what they are supposed to do.

I tried a different brand and had nothing but issues. I have over 3k of these pixels and all work great. The only negative is that the connectors are not waterproof and will corrode if not kept dry. Still a great product and reliable.

Great lights. They are very bright and easy to install. I deducted one star only because extra male and female ends would make "jumper" wires easier to make. The video shows 670 lights.

Gateway drug into the world of programmable lighting. You can find WS2811 pixels from specialized vendors for cheaper, but these are the best on Amazon. Years later, and I'm still using mine! They eventually turned into a Christmas light show with nearly 10,000 pixels.

I bought 2,000 of these lights a year ago and installed them permanently on my home under the eves. I mostly followed a video guide I found online from a DrZzs on youtube. I recommend the 12V version of these instead of the 5v. These are very bright lights. In the 2,000 lights I received, I only had one pixel that stayed red no matter what color it is supposed to be. It is easy to splice in a new pixel, just make sure you maintain the proper direction. IMPORTANT INFORMATION ***** These only work in one direction!!! ***** what that means is if you cut and splice sections or pixels, make sure they are all fed from the same end of the strand (male vs. female). If you accidentally get one backwards it will not work. Big bummer after you spend 2 days putting them up on your house! I found that if I plugged in more than 7 strands (70') they started acting funny. The voltage dropped from 13.5V to 11.5V after 70'. Instead of injecting power every 70' or so by running feeders from the power supply, I just bought (3) power supplies and fed them from both ends and the middle. The 12V DC power supplies I bought on Amazon were $18 ... cheaper than the wire I could buy for feeders. I also used the Magic LED SP105E controller, which connects to your phone via Bluetooth and allows you to change the lights to one of 200+ shows. Absolutely highly recommend these lights as you can use them for all holidays, parties, or whenever!

I decided to get creative for Halloween and create a Tunnel to Hell. I'd never used an Arduino before nor done any electronics, but I was able to get this up and running as I wanted in a few days. I bought the 5V 500 pack which are actually 10 sets of 50 LEDs which you can daisy-chain together. There were three things for me to understand before I got them working: controlling them, powering them and ensuring I had enough RAM. CONTROLLING THEM The LEDs only require two connections to the Arduino board, which involved identifying the red, white and blue wires on the main LED cable, then connecting the white signal wire to one of the comms connectors and then connecting the blue ground wire to the GND connector. Controlling them is easy if you use a library called FastLED, which has a great help community on Reddit. The library can be added in the Arduino software via Manage Libraries and comes with some easy to understand examples. POWERING THEM The Arduino itself can't power enough of the LEDs so you'll need to connect a power supply. I bought a 5V 2amp power supply which I connected to the loose red and blue wires on the LEDs by screwing on a DC power connector. For my project, I hardly use any of the LEDs at the same time so 2amps seems to be enough, but if you use all the 500 LEDs at once at full brightness in white it can use 30amps! For this, I understand that you need to 'inject' 10amps of power along the strands at three points using three power supplies connected via a DC power connector, although the 12V version requires less injection points. I'd recommend buying a single power supply and then seeing if it's enough to power your project. RAM I started using the Arduno Uno r3 which worked for up to 450 LEDs. To get all 500 working within RAM I needed to upgrade to an Arduino Mega, which cost a little more money but worked the same as an Ardunio. I actually used an Elegoo Mega, which is a compatible copy. Overall the LEDs seem good quality and work as described. They're a bit smelly from the manufacturing process but perhaps that will dissipate over time.

no es IP68, es IP65, y no es 0.3W es 0.5W ... es mucha diferencia de precio por el indice de protection y por la fuente adecuada. yo elige este producto por eso y veo que el es igual que muchos con un precio superior. a parte, el envio fue rapido y el producto coresponde a la foto de venta. Una disculpa... Yo quiero un producto IP68... y no lo tengo

Worked as described no buyers remorse

I love these lights. I ordered a second set. The delivery is prompt -exceeds expectations. The quality is superb

I use these to get the old school marquee style sign look. Very happy with them.
