FCOB COB LED Strip CCT Flexible High Density 16.4FT 640LED/m Tunable 3000K-6000K CRI 90+ Dimmable Light Ribbon for Bedroom Kitchen Indoor Decoration DC24V(No Adapter or Controller)

These are outstanding strip lights. The color is great, they can be super bright or very dim, and the color looks great. Easy to install, I used aluminum LED channel to mount this under my kitchen counters. The adhesive backing is very strong, so make sure you have it lined up right when you are installing. The lights give me the ability to choose between bright and energetic or warm and relaxing. I used a Gledopto controller and Home Assistant, the lights work very well in the automations I set up. I have approximately 8 meters installed in my kitchen and use a 10A power supply - no color changes or problems even at the very end with no power injection at any point. I did have to buy some kits to make 90 degree turns with this, however the end result is a stunning set up that really makes my kitchen more useful and inviting.

***UPDATE*** In the short time since I wrote my original review, they changed the product specifications from "72 Watts" to "36 Watts" even though if you search for "Watts" or "Power Supply" in Q&A and Reviews you will see that their answers are all over the place like they have no product knowledge of their own product. But a little research helped me decide the 48W supply would work. I also finished my kitchen under cabinet lighting project. First, I got rid of their cheap factory connectors that used 22AWG wire and cut and soldered feed wires, using 3-wire 18AWG copper stranded, to multiple sections of strips, the longest section being 30 inches for a total of 10 individually wired strips. All the sections were wired in parallel, meaning each feed wire and strip section went directly back to the output of the controller(kinda like power injection), thus eliminating most of the voltage drop so I could make sure their included 48W power supply would work. Running them in parallel also helps in the future if one strip section goes bad, it will be a lot easier to just change out that one section. For 5 of the sections, I had to run power from the controller across the ceiling in the attic, thus the main reason I decided to use 18AWG. Also, 18AWG is the thickest gauge wire I would attempt to use, gotta be really careful when soldering. The copper pads I had to solder to were nice and sturdy and none "ripped" off during the whole process. I put all the sections in aluminum diffuser channel with extra double sided tape between the aluminum and the strips as an extra precaution against any short circuits. This was recommended by either BTF or the channel manufacturer, I forget, but it worked nicely. I am actually currently installing "over" cabinet lighting using a different popular brand XXX found on Amazon led strip lighting manufacturer, and have had issues with a few of XXX brands copper soldering pads tearing off and had to run jumper wires to the next pad. BTF's led strip was way nicer to work with. I went with brand XXX because I was kinda pissed off at BTF's wrong power supply specifications. Should have controlled my temper and stuck with BTF, a higher quality product!!! I am also upgrading the tiny controller with tiny 22AWG wire that came with the kit to BTF's C02W controller and BTF's WR02RF remote to control both under and over cabinet lighting. Using the C02W, I can easily use my 18AWG wire to run everything. (Reviews for C02W and WR02RF still to come, installing them is today's project) I will also be using a different brand XXX 72W power supply for over cabinet lighting to compare. My setup: 1-BTF 48W supply(under), 1-XXX brand 72W supply(over), 2-BTF C02W controllers(1-under and 1-over) and 1-BTF WR02RF remote for now. Overall, a very good quality product and the tunable lights work awesome from the temperature range to the dimming!!! The most important thing is that my wife and I love them!!! ***Original Review*** Product Specifications state 72W power supply in kit. I received 48W power supply. Power=Current x Voltage. I received 2A x 24V=48W power supply. Still have not figured out what they are referring to when they put "72 Watts" in the product Specifications. If it's the required power, why do they include only a 48W supply? Also, power specifications listed on their own website and Amazon are very erroneous when they talk about Watts per Meter required for their strip lights. I could never figure out a definitive answer along with other reviewers on Amazon. They say W/M required is anywhere from about 12W to 14W or so per Meter. My kit was a 5 Meter bundle which included power suppy. Well, lets take the low side and use 12W x 5M = 60W. If you take into account you only want 80% power supply capacity continuous, they should include at least a 75W supply. It's like they have no understanding of Ohm's Law, Watt's Law and being a knowledgeable seller law. Also, from their website, the smallest power supply they "Recommend" for the 24v 16.4ft strip I received is a 24V x 5A = 120Watt???...And they include a 48Watt, not even half of what they recommend !!!

Tunable white color strip light at its best... bright, consistent light, dimmable with controller and smart life ap... I would get the more expensive controller (20 khz), as the lower priced one has a little bit of a high pitch noise (even with high quality 24v transformer) (use BTF-LIGHTING CH21RF 2.4GHz RF LED Controller 20kHz High Frequency PWM Silent No Humming); if your running more than 1 strip (16'), might want to direct wire (3 strand) to ea 16' section, as end to end will have dimmer sections the farther away from transformer

I bought these for my first diy lighting project. Overall, they're fantastic - I love that it came with some extra bits and bobs for customization, and they work well with the controller and silicone tubing I bought. While I don't love the look of them out of the diffuser, they look FANTASTIC in a diffuser. However, several months in, while most of the strips I bought still work perfectly, one of them has started flickering. I've double checked all my wiring and connections, and unfortunately I think it's the strip that's gone bad. However, given that all of the rest of them work still, and the build quality seems very high, I'll be giving them another chance and will be replacing that strip with these same ones. For the price, and brand recognition, it's hard to beat these.

nice quality light strip

The LED strips work and seem to be bright enough to use for lighting. But, if you're doing anything but plugging the strip into an existing, pre-made controller, be aware that BTS-Lighting does not send any of the normal technical info about the LED strip. Parameters like max wattage or max current on the V+ lead are not available, and if you email BTS-Lighting they are useless. I've been trying to ask them a simple question, "Is it within spec to drive the Warm-White and Cool-White at full at the same time, or is it only one at a time" and they can't answer me. Each time they invent a different question that I didn't ask, and answer that instead. I can provide some info from my testing: The Cool White LEDs draw 300mA per meter at 12 volts. That's 3.6 watts per meter, or 1.5 amps (18 watts) for a full 5-meter strip. The Warm White LEDs draw slightly less, 280mA per meter at 12 volts. That's 3.4 watts per meter, or 1.4 amps (16.8 watts) for a full 5-meter strip. No other information is available, including: * Maximum watts per meter (when cross-fading between WW and CW) * Maximum current for either the WW, CW, or V+ leads * Max bending angles or other mounting guidelines * Any other LED specs you'd typically see in a datasheet. (All you get is "plug the wire into your controller".) I'll end up having to do tests to find out for myself, possibly losing a length of LEDs in the process. That loses this a few stars, because they could have just copy/pasted some info from their supplier's datasheet and it's costing me time.

Used in conjunction with diffuser channel makes for excellent indirect lighting or even direct lighting. Also used an LED dimmer with fantastic results in kitchen counter lighting. A dimmer is recommended as this strip is bright, unless you like very bright work spaces.

SORRY - I WISH IT WASN'T SO... This is NOT for DIYers... my electrician couldn't figure out how to light this up Heck, the customer support I conversed with for over two weeks kept giving me wrong 411 - which I kept correcting (and I am NOT an expert or have the slightest bit of knowledge on this--just logic....) So we got a bunch of these to light up our island and the thought was to connect to a single controller then to power it up. When we ran wattage calculations - it was huge - it's 23w per meter and each rolls has about 5 meters, so that's about 115 W per roll - that's A LOT (I am told). Anyway that's not even the issue - the controllers 650E or 550E do not work! Tried various formations and nothing turns it on. All this to say - the lights do not come with good/doable instructions. It's not clear how to get them to turn on, how to control them. etc. Such a bummer and what a huge waste of $.
