BTF-LIGHTING WS2812B 16.4ft 5m 60LEDs/Pixels/m 300LEDs Black PCB IP65

These are great...work perfectly with my Arduino systems, great for art projects, computer controlled lighting etc...

This is my second purchase with these chapies, with no issues.... Thank you BTF, good effort!!

The lights arrived promptly and in good condition. I ordered 8 on this occasion quite a lot for a new hobbyist but I had ordered one previously and the kids liked it so thought I'd get some in for some future projects. I am new to working with these and ESP32s but have now got a basic understanding although I don't solder yet, 7 worked perfectly, but unfortunately one of them has an issue and keeps intermittently going out or not working properly. I can't see anywhere to contact them directly on Amazon so if they read this hopefully they can contact me regarding this issue.

Bright, responsive. Ran for Christmas via an Esp8266. Only issue - the adhesive tape on the back is crap. But it always seems to be on light strips.

Who's at fault here? Overnight this item increased from £31 to £40. The last set I bought were manufactured in 2017. So you'll be paying an exorbitant price for something made 6 years ago. Buy from another supplier. Nothing special about BTF stuff and the adhesive is terrible. Avoid.

Ottima striscia di led, ho preso la striscia con pcb nera da 5 metri e di 60led/m di densita, controllata da arduino uno per accendere ogni singolo led di un colore diverso, molto luminosa, nessun led difettoso. La parte bi-adesiva dietro non attacca molto bene, ma si può risolvere facilmente. Inolte e importante usare 5v e non 12 altrimenti si rischia di bruciare i led, e bisogna rispettare la direzzione in cui andra la corrente(freccia disegnata in bianco) dall'alimentatore e le informazioni dei colori di ogni singolo led(cavo verde) Per calcolare la potenza dell alimentatore bisogna motiplicare il numero dei led per 0.06(Ampere) che è il consumo massimo(luce bianca e luminosità al massimo) Esempio 30 led x 0.06= 1.8Ampere 1.8 ampere x 5volt = 9 watt Per la striscia intera 90 watt

UPDATE: The seller contacted me and indicated that I likely received a second hand, returned item and that was the cause for the damage. While I have been able to fix the unit I received with a little effort, the seller is going to send me a replacement. The responsiveness and customer service of the seller were excellent! As the item I received actually functions and the seller is making it right by sending me a replacement and a couple other items at no cost or obligation to me, I have updated my rating from 3 stars to 5 stars. The lights themselves really are good and work well. ORIGINAL: When I went to remove the lightstrip from the bag, I noticed that it was not fully wrapped around the spool. As I carefully pulled it out, I noticed that a portion of the strip was bent over on itself. Upon further inspection I noticed that some of the silicon covering that makes it moisture resistant had been damaged at about the third LED in the strip. Other than that it appeared intact. I plugged the string into a controller I had purchased separately and the lights lit up. I had other issues with the controller. However, when I touched the lightstrip, the lights flickered a bit and went out. I touched it again and they flickered again and came back on. I noticed that by flexing the damaged area, I could make the lights go on and off. Either there is an issue with the "wiring" in the strip or there is a bad solder joint. Either way, I can still make the strip work, but I took off a couple stars because of the damage and the fact that I'll have to do a bit of work to make them 100% functional. Not worth the time and effort to return them and play the replacement lottery when I have the know how to fix them.

Embalaje perfecto: cualquiera se esperaba o directamente ningun embalaje o una bolsita de plástico. Sin embargo viene en una bolsa con cierre hermético zip (el de las bolsas de congelados) y un impreso muy profesional. Muy buena impresión. La tira de LEDs parece de muy buena calidad. El revestimiento de protección es muy agradable al tacto, parece silicona. Y viene lo que se había anunciado: con una densidad de 60 LEDs por metro. Perfectamente aceptable.

Excellent! Works as expected, with amazing customer service.

Lo he comprado para hacer un adorno luminoso de Navidad. Con una fuente de alimentación de 5V 20A y un pequeño microprocesador Arduino UNO con las librerias adecuadas para estos LEDs se consiguen unos efectos de luz espectaculares aunque, si no se tienen conocimientos de microprocesadores, se puede adquirir un controlador que permite seleccionar distintos efectos. Funciona perfectamente y la calidad es mejor de lo que esperaba. Tengo la versión resistente al agua.
