BTF-LIGHTING 5050 RGBW RGB+Warm White(2700K-3000K) 4 Colors in 1 LED Tape Light DC12V 5m 16.4ft 60LED/m Multi-Colored IP65 Black 12mm PCB for Bedroom Kitchen Home Decoration(No Adapter or Controller)

Good: Bright in all colors. Wired on both ends of the tape, one male & one female connector. Comes with a spare M connector in case you have to cut and daisy-chain it. Ran cool in my initial 30-minute test. Tape on back sticks well (but see below.) Bad: The double-sided tape on the back is not applied correctly; every foot or so there is a 2-3 inch span where the light tape lifts off the sticky tape, requiring you to cut the sticky tape to make it lay flat and leaving un-stuck stretches. It didn't matter much for my application, but would have if I'd used this for e.g. under-cabinet lighting. Bottom line: The product itself seems pretty good, although I haven't done a proper burn-in test yet. The sticky-tape issue, however, turned a straightforward application into a difficult, tedious job. Five stars, but the sticky-tape thing came very close to costing it that fifth one.

After initial testing, this is an excellent product. I bought 5 different styles of LED strip to test out in order to find which ones I wanted to use for my house lighting. This strip outperformed all the others that I bought in every way. It's very bright, the colors are very nice, and the warm white is very pleasant. Also, because it uses the 4 in 1 LEDs, all LEDs on the strip are always lit up evenly whether you have it set to a pure white or a mixed white or a pure color or mixed color. This is important because my preference is for a finished project with LEDs that aren't noticeable, and to be, rather, strips of even diffuse light. I haven't adhered them to anything yet, but because I'm using aluminum channel with diffuser covers, I may not even be able to tell how well the adhesive performs very accurately, so I am not leaving any rating for the adhesive. The 24v strip has the further advantage over an equivalent 12v strip of having less voltage drop per given length of strip due to lower current, and lower current makes everything easier in the long run, by allowing smaller gauge wire to power each strip vs the same length wire run for 12v. For my applications, concealment of wires leading to the led strips is important, so being able to use a smaller gauge wire is great, even if the difference is minimal. I would say that for large projects, the requirement of a relatively high current output 24v power supply is harder to acquire than a 12v supply, particularly because I had already planned on using an HP 1200w server power supply, but ultimately it just means I have to use two 12v server PSUs in series, which is not really a bother. Please note, I don't advise using power supplies in series unless you are confident in what you are doing, as wiring something like those server PSUs in series without removing the ground on the AC power cords is a quick way to convert the power cords into magic smoke.

Very nice light , happy with them

Used for undercabinet lighting and installed these in tracks with a diffuser. Soldering to the strip is tricky, and the copper pads are VERY fragile. Several of the individual R G B W DC+ pads pulled off with the wires even though I handled them gently. I ended up trimming the strip a little more, then soldered wires and used a glue gun to help hold the wires and pads on. That seemed to work OK. Also, there seems to be a slight difference in LED spacing where the manufacturer's splice is made mid strip ... it is subtle, but noticeable. Overall, a decent bargain, bright, and reliable so far.

I bought these to add additional lighting inside my Bambu Lab X1C printer, which is controlled by a Dutch Developer BLLED controller. These work perfectly for that purpose. I am using different TPU gaskets for my AMS riser as well as an additional L-bracket for the front that orient the LEDs to face downward toward the bed instead of inward, so I had to cut and wire 4 separate strips. It was a bit tedious to do all of the wiring (lots of small gauge wire and soldering, lol), but the end result is a fantastic upgrade in interior light output. The BLLED controller allows for white light during printing or standby mode, turns off the LEDs during the lidar scan, turns them blue during bed leveling, green when a print completes, and red if theres an error. Pretty slick! Higher chamber temps during ABS/ASA printing hasn't affected them at all. Highly recommend these LEDs! Plenty left over for other projects too, and although these are more expensive on Amazon compared to places like AliExpress, the much quicker shipping time via Prime was well worth it.

After only a couple of weeks the led strip stops working... offcourse just a couple of days after the return time🥲 would not recommend

Correspond à mes attentes le produit est très bien

The length is amazing and the brightness is perfect very easy to install comes with only one warm color range light still the quality is amazing

Colours are very intense, but after carefull installation into aluminium profile on led coving a section of the red channel has stopped working within days of installation. It's all stuck down so I can't remove it to return, to fix it I would just solder in a repair section.

De très bonne qualité !
