WS2812B 3.3FT 1m 100LEDs Individually Addressable BTF-LIGHTING 5050SMD LED Flexible White PCB WS2812 LED Strip White Board Dream Color IP67 Waterproof DC5V for Indoor Lighting

...and they're at 1cm spacing. Which is what I was after. Thanks BTF.

Set this up on my custom 3d printer, hooked up to a 5a buck converter and the SKR main board. Works just fine with the separated power supply, and printed roughly 100 hours with no drop in brightness or colour.

The media could not be loaded.  Have had these led's up on an aluminium track for a couple of months now. 1st of all, arrived very well packaged in their own aluminium foil packs. Once opened, was very happy to see that they have 3 pin connection blocks at both ends ( I cut these off so I can use a smaller connection block but they are handy to have to connect to my led controller ).I have used 3 packs of these led's to go right around the room they were going in and managed to stick them to the aluminium track I installed easily enough.I use wled software and the dig quad controller to control the effects of these led's and even though the software will limit the brightness due to the power limitations of such a long continuous strip, it is still very bright even in daylight. ( white is limited to around half power on a 13m long strip ). I might still go the power injection route to see if can push the brightness to full but in all honesty, it is not really needed for an inside installation.After a couple of months use, have noticed that some of the adhesive has come off the strip in certain areas and have had to glue these down. ( hence I give these 4 stars).

I purchased the 1m 60 LED version of this strip for my PC which has a Dark Base Pro 900 case and Asus Strix X299-E Gaming motherboard. This particular motherboard has a header on the board and comes with a cable for connecting it to WS2812b addressable LED strips, which can then be controlled with the Asus Aura Sync software.After installing the LED strip and connecting it up to the motherboard it works perfectly and is also very bright. The LEDs are individually controlled so you can have, say, a rainbow or gradient effect across all of them etc.One issue I encountered when trying to install the LED strip to my case was that the sticking backing isn't very strong and starts to peel off from the inside of the case within hours of being installed. In the end, I found the best way to attach the strip was to use some sticky fixers (double sided foam pads) which are very sticky, and they have secured the LED strip nicely. Just be aware that you may want to buy some if you intend on using this strip inside your computer!The LED strip has wires and connections at both ends. At one end you have a 3 pin male plug (this fitted into the cable for my motherboard) and the other end has a 3 pin female plug, presumably to chain additional strips together. Both ends also have an extra red and white wire (with exposed ends), which is for attaching to an additional power source. I didn't need these so I cut the exposed tip off and sealed them in shrink wrap although you could use electrical tape or simply cut them off altogether.I also had to remove 3 LEDs for this strip to fit in my case properly. It was simply a case of cutting the strip with a pair of scissors where the white intersection line is marked. The really cool thing about this strip is you can cut the strip up and solder the strips together using 3 wires (+5v, GND and Data) between each strip.

I bought a couple of these and they were a struggle to get working. Part of it was down to my inexperience but:1) If you're using an Arduino or Pi to control these you're going to need a logic level converter before these LEDs function. If you connect them to a 3.3v data signal they do nothing without the data signal being stepped up to 5v.2) The sticky tape is already failing in several placesIn desperation, and to test using a different set of lights to rule out issues, I bought a set of CHINLY LEDs, which are the same spec. These work without the need of a logic level converter (though they respond much better with one) and they're still sticking to my MDF.I don't think I'd buy BTF LEDs again.

Product: "Black PCB IP67"Very nice product. The following may be issues of concern for some purposes:1. Brightness levels are not adjusted for the human eye so although the brightness is fully adjustable in 256 steps, these are basically bright right down to the lowest values. Difficult to produce a nicely graduated fade-out.2. As stated this strip is made up of two half length strips joined in the middle. The consequences are not mentioned:2.1 The joint appears to be a simple solder link, more rigid and fragile than the rest of the strip.2.2 The joint is about twice as wide as the other gaps between LEDs, causing a visual discontinuity between the two halves.In fairness there is another side to issue 1: These LEDs are brighter than other neopixel-like strips I have tried. So while my displays aren't graduated so well on this, they are way brighter.On balance, full marks.

Hyperion light system. Worked great but the sticky backing does not stick properly.

if anyone could tell me what power supply they are using id be more than happy to buy it - i brought 2 sets of these and have had to send them back at not workingThey just blink every so slighty its as if they not getting enough power.I think they should sell these with power supply as well - they look awesome lights but so far ive not been able to use them.
