BTF-LIGHTING 5050 RGBW RGB+Warm White (2700K-3000K) 4 Colors in 1 LED 5m 16.4ft 60LEDs/m Multi-Colored LED Tape Lights IP30 Non-Waterproof White 12mm PCB DC12V for Bedroom Kitchen Home Decoration

Striscia led 5 mt. rgbww conforma a quanto in descrizione. Funziona bene. L'unica modifica che ho fatto è taglarla in due ed alimentare individualmente i due tronconi da 2,5 mt per evitare cadute di tensione e quindi variazioni di tonalità. Il biadesivo sotto alla striscia non è particolarmente forte ma comunque sufficiente. La consiglio

Lovely item but be warned that the strip is a full 12mm wide so it doesn't fit many aluminium profiles. Even some that say they are for 12mm strips don't fit. So great item but just make sure you get a profile with lots of space.Give a wonderful bright light. These really are very nice indeed. Much better spread of light than the older, cheaper strips that have an RGB LED and separate or no white led.Course you pay for it, but if you need high density, even lighting then these are the only option.The strips have a very high density of LEDs and they are super bright. I used them for backlighting a large wall mounted monitor and the overall effect is stunning.The strip has power connections at both ends and you do need to use both if you use more than half the strip. I experimented and found that at full load (120W) the wires will melt if you only use one of the connections. What I do is to cut the strip in to appropriate lengths, no more than 2.5 meters each. You use those kits of connectors to go round corners or add extra power cables.If you want to backlight a TV, that works out at about two individually powered strips that are 1.6m each for a 50" TV. Each strip has one corner in it.It's a fiddly process, but it's worth it. These strips are awesome and the final effect is amazing.The prices is too high now. There are other identical products on Amazon for a lot less money. So while the product is still a great product, you need to fish around for the best price.Highly recommended.

Estaba contento con el producto, tenía unos 10m y daba buena intensidad de lud, ha sido meterle 3 ó 4 metros más y mirad lo que pasa. He visto que el fabricante dice poner 12v en la cola del led, pero no se como se hace, alguien lo sabe?Un saludo

These work great

I bought these 5050 RGBW LEDs along with aBTF-LIGHTING AC100-240V to DC12V6A power supply and aBTF-LIGHTING Zigbee 3.0 C04Z LED Controller for RGBW, after lots of research and a certain amount of educated guessing, and that combination worked flawlessly for me out of the box.The LEDs come with a cable that connects the pin sockets on the end of the strip to individual wires suitable for insertion into the controller. When inserting each wire, pay attention to the wire color! The order of red and green is switched on the controller relative to the pin order on the LED strip, so you'll need to cross-wire the wires. The colors of the wires in the cable that comes with the LED strip matches the pin order on the strip, so just attach the red wire to the "R" socket on the controller and the green wire to the "G" socket, and you'll be fine (unless you're red-green colorblind, in which case, best of luck!). The controller also comes with two sockets marked V+ (power). Attach the black wire to one of them and leave the other one empty. This advice probably applies to their RGBW controller that has a remote control too, but I can't say for sure.If nothing happens when you plug it in, make sure the plug between the wall socket and the power brick is firmly inserted. It took a fair bit of persuasion for me to get it fully seated.Anyway, on to the actual review: the LEDs are spaced close together on the strip, which is good since it makes it easier for the light to diffuse and be less spotty. I was pleasantly surprised to see that there are cut points every three LEDs, which makes it possible to cut the strip to almost any length you want. These cut points do seem to be natural places for the cable to crimp when unwound, though, so be a little careful playing with them before you attach them to something.The colors are pretty spectacular. I can produce a warm, pure, or cool white with these, plus vibrant saturated colors, and the hue stays pretty consistent even as I lower the brightness almost to nothing. The colors produced also match what the app shows, unlike some cheap smart light bulbs I've bought on Amazon in the past. The maximum brightness is very bright indeed.All in all, these lights work exactly as they're supposed to, they're well-made, and setup was way less of a hassle than I anticipated.
