JOYLIT 24V LED Strip Lights White 6000-6500K, 16.4ft/5M Flexible 300 Units SMD5050 LEDs, No-Waterproof High Bright LED Tape Lights (LED Strip Only)

Got these LEDs to put in my Ender 3D printer, after seeing the idea on you tube. It was like they were made for it! The lights are made in segments of 6 lamps. The string can be cut at these joints. Every 5 joints the string is soldered. Must be the way they are manufactured. Heating these joints allows the string to break without cutting. A string of 6 segments is the perfect length for an Ender 3. The string will perfectly slide down the insides of the gantry towers and cross member. I milled out holes on the bottom of the gantry cross member, near both ends, to allow the LED string to enter the uprights. This kept the string completely inside the channels. Solder a few inches of wire to end that terminates near the power supply. Inside the power supply are unused power terminals to power the LED string. I also added a switch to the power-supply holder, but it really isn't necessary. Great white light that perfectly lights up the print-bed during printing. I'm sure these would fit a CR-10 (or other V-rail printers,) but I don't know about the power supply part of that kind of printer. I bet they would look good for counter-top illumination too! :-) You'll have enough left over to light up several more printers!

So I went to a friends house a year or so ago, and he had a blue light behind his TV. It looked so cool! I had to have one. Got this CHEAP last year. Unlike his, Mine will work with both Google and Alexa. Wife likes green, I like blue, so we alternate. Really cool using green for a sporting event, or blue for a shark movie. Very easy to install and well worth the price.

Used these for lighting the build plate on one of my 3D printers. The strip is a close fit inside the 2020 aluminum extrusions. So close that the adhesive backing is not needed, the strip will simple sit in the v-slot and is too wide to accidentally pop out. The only trouble is that the width makes it difficult to bend and stay in the v-slot at the frame joints; my first go resulted in damage to the strip and fuses or resistors popping off the strip. This was my fault for trying to brute force it in place. On a second path, was able to partially fold the strip without causing damage. Paired with a simple dimmer dial, the strip works excellent from about medium brightness up to VERY bright. Would definitely purchase again should I need more on another project.

I used some of this to illuminate the dust shoe on my CNC router at 24v, held in place with normal hot glue on the LED side (since I had the lights shining down through thick acrylic). I also ran a fairly long run under kitchen cabinets reusing an old 18.5V laptop power supply. I found that at 18.5V it was running around 110mA per meter, which at around 2W/meter power consumption is slightly less than the suggested 5W/meter (but I'm not complaining). As expected, running at 18.5V I get less light, which in this case was precisely what I wanted.The adhesive backing, unsurprisingly, is not much good for anything more than temporarily positioning. I suppose it might adhere to clean, smooth, porous surfaces but I just used a bit of hot glue here and there. I purchased these fully expecting that the adhesive backing would not hold for long.I did not find these ran too hot. The ones I'm running at 24V definitely get warm (around 40-45C), but the ones I'm running at 18.5V stay considerably cooler.Once these are off the spool it's fairly easy for them to droop onto the floor, and stepping on them can damage them. Fortunately it was fairly easy to resolder the one resistor that came partly off.The soldering pads on the 10cm segments are fairly generous. All in all, a great value.
