WS2811 Pixels Digital Addressable LED String Lights Waterproof RGB Full Color 12mm DC 12V 5V (DC12V 500pcs)

I needed something to dominate the neighbours in their outdoor Xmas light game so bought these to dominate them. Connected all strings with waterproof plugs and sockets, powered with a 12v supply, a wemos D1 to control and a cheap level shifter to run that using WLED. I used all 10 strings. No power injection needed as long as they are not all white. I had zero failures out of the 500 and they survived wind, rain and snow and low temps for two months, no problem. The leds are very bright and colourful, from pastels to bright primary colours and reacted quickly. Highly recommended. Utterly mullered the neighbours and will be doubling up this Christmas.

I bought 2 sets of 500 lamps. I'll be using these for 3d effects on a tree (not just for Christmas) following standupmaths (youtube) ideas. The product is great. The smell reported by others faded quickly. I did have an issue with one segment, however customer services were polite and efficient and replaced the faulty segment quickly.

wire between led’s is as advertised but is the bare minimum length. 1+ extra inches between led’s would be more useful.

I used these to make a video matrix and they are amazing!

Many other reviews already cover the use of these lights so I won’t reinvent the wheel. As per other posts, you do need to inject power at multiple points. I was using a 30A supply and still limiting the overall brightness using FastLED. All powered via a small Arduino and using FastLED as the driver. Lots of different colour routines. I’m not sure that all of the neighbours all love it, but our Christmas lights are certainly different and 100% bespoke. Yes they do smell like a bag of salt and vinegar crisps to start with but the smell does wear off quite quickly. In hindsight I probably should have went with the 12V version given the length of LED’s that I have.

seem to be good quality and a speedy, helpful response from the seller to my queries

Used around 700 so far, no issues, great leds.

You need to pair them with a controller, I use a Dig-Quad, in my testing all the 500 pixels worked well, no lemons. I was able to mount these to the first level of my home, without any problems. These lights are the best ones in my neighborhood because I'm able to change them to different patterns. I did notice that the price for these has changed recently, I got 500 pixels for $219+tax which I thought was a pretty good price. At the higher price, you guys make your own decision.

Worked as described no buyers remorse

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!

Let's start with cons : The SMELL, They smell so bad for days, had to leave them outside. That plastic smell that a lot have mentioned. Spacing between pixels is too tight. Hard to get to 3"without pulling hard between. Came with couple pixels werent waterproofed (no epoxy inside) Now the good stuff: Seller was quick to address "the no epoxy issue" in those couple pixels to my satisfaction. All pixels work during initial Testing and for almost 3 weeks now outside ON for about 8hrs/day Minimal power injection needed with the rexin. The wiring seem smaller compared to other pixels I use from a different vendor but with the Rexin, I do not need any power injection. ( I needed power injection with the other pixels from Ali while using 250 in a row) At this time, I have over 900 pixels divided in 4 channels 250-196-239-229. Color accuracy is great and no issue with flickering or data problems with these. Refresh rate is a bit slow but I am not sure if that is controller or the pixels.. They been up on my house for 2-3 weeks now and no complaints, Will update review if that change. Overall Im quite happy with this product
