Rextin 16.4FT 5M WS2812B 300LEDS RGB LED Strip Lights Pixels Addressable Individulally Dream Color Chasing DC5V Digital Programmable IP66 Tube Waterproof (White PCB, IP66 300Leds)

contrary to another review there was absolutely no issue at the soldered joint, you cannot find them without looking hard. they are pitch and position perfect.. Just fired them up with the Raspberry Pi 4 to test them, no noticeable issue with voltage drop along the entire 5m, and they also run direct from the rasppi 3.5v logic so no logic shifter needed. The LED's are bright, even with lights on you can see the colour effects lighting up the ceiling. This is an LED stip to buy, and its about the cheapest too!

I use these strips to make all kinds of lighting effects. They are easy to work with, are super low voltage and last a long time. They are also great for using with arduinos. I've used them with Nano, Uno R3 and the Mega without any issues. If you are using a longer length you will need to add extra power at different intervals or the colours will not be the same across the entire length and the leds will dim. These are my goto strips for the stuff I do.

These strips are pretty great - they seem to be well made and well (enough) jacketed in silicone. Mine are outdoors (although not in the frost), and despite being in alu. profiles, they do get wet when it rains. I haven't seen any signs of water ingress into the strips themselves. They come with a leaded connector on both ends, but this is no way sufficient to provide power down the length of the strip. You'll need a power "tap" every 1-2M along the length, otherwise you'll see some discolouration as the LEDs struggle to illuminate properly, at least at higher brightnesses. However, once you've sorted all that out, they look great when running, and they're close enough together that a diffused cover over them does a good job of sort of joining them up. From a controlling point of view, they're easy enough if you're handy with an Arduino or Raspberry Pi. I've had a few of these strips, and should the voltage of the data line exceed the supply voltage, then you'll break the chip on the end of the strip (which you can cut off and then just use the next one, if you need). Other than that, getting data into them is pretty easy and reliable enough. I have seen some updates fail to set every single LED correctly every single time, but they always seem to fall in line the next time you update the strip. I've noticed that setting an LED so say (1,1,1) gives you a fairly bright light, so the numeric range is "squashed" into quite a small optical range. It's a shame you can't get them to be really dim, but by no means any terrible issue. One gripe I have though, is that the green LEDs seem to be failing in a couple of lengths. On one 5M length, I've (so far) had 27 green LEDs fail, and in another 5M strip, maybe 3-4 have failed (and some of them seem to have failed during a week of being switched off). In the other handful of strips I've had, there seem to be no failures of any colour yet though. I assume "a dodgy batch" or some such, but it's annoying to have to replace them. I can't see any serial numbers or manufacturer tracking, so there doesn't seem to be a way to work out if they're good or bad without trying them out. One last thing, which is nothing to do with the strips themselves really is the commonly suggested use of silicone to seal up cuts and breaks - I'd advise against this, because silicone can be a little corrosive to soldering and such like as it dries. Instead, a hot glue gun works a treat (and dries far quicker!).

They have a good brightness about them, even though I only have them at.approx 30 percent brightness. Nice colours and they respond how I expected them to. Hooked up via an Arduino Due and sparkfun spectrum breakout board.

Great Product and fast response on questions I needed answering, WS2812B works great, thank you.

Fantastic product, does exactly what I wanted it to do. Very bright LEDs which are required for a DIY ambilight setup. Excellent quality strip light and will be purchasing again for any future projects. I had a technical issue that Rextin were happy to sort and a replacement came in a couple of days over Christmas too! Couldn't do enough to sort the problem as quickly as possible.

Used to provide backlight effect to picture... Worked well

Whilst the strip worked well, I was disappointed to see that it was made up from so many different pieces. Over the entire 5 metre length, there were 8 soldered joints, and most of the joins weren't consistent. The pitch between the LED's varied considerably and some were also not completely centred. This might be acceptable if the strip is to be used as it is, but when cutting into lengths to make a matrix, this causes misalignment of LED's in columns, so I had to break the joins and resolder each one to the correct pitch and alignment. Maybe that is why these strips were some of the cheapest available on Amazon at the time?
