I got two 5 meters RGB LED light strips and would like to connect them together, controlling them as a single strip. Each strip power is 72 W, the input voltage is 12V, it has 300 5050 SMD LED emi... More on electronics.stackexchange.com

Rather than buying 5-6 of these kits, I would suggest finding them without the whole controller and buy 5-6 or however many strips you need (making sure they're designed to be connected end to end and are able to handle the load of 5-6 strips running through the closest one to the power supply. Then find a controller or build one that has the capacity to do what you want. Don't think of it as 5-6 strips, once they're connected they're basically just one long strip, with connectors and wires. You need to know how much power that whole big long strip is going to need as well as any impedance from the wires and connectors. There's also a few things to keep in mind about the strips themselves, some will have individual LEDs for each color and may not blend the individual colors together as well, so for your application with it's close proximity I'd avoid those ones and make sure that each of the LEDs on the strip is an RGB LED where the LED consists of 3 smaller LEDs in the same small package, these will give you more defined colors, although some will still need to be a certain distance from their target to still be able to blend. The cheaper ones are analog where all LEDs light up the same color and brightness at the same time. These require a controller that will treat your 5-6 strip long single big strip as 3 separate strips, one for each color. There are a number of controllers similar to the one in your link above that will work for varying prices. With a little research into your needs, building a controller yourself might also be an option to consider. A simple basic one would consist of 3 knobs on a wall plate (one for each color) which by varying the positions you can create any color you want. A more complex one could use a micro-controller such as the Arduino to give you much more flexibility with what method of power and control is best for your needs, whether it's a remote like in your link, or an app on your smartphone There's also individually addressable LED strips, where each individual LED can light up it's own color, this allows some really neat effects like color chasing, different areas having different colors, etc. These require a more complex controller than the analog type where all LEDs are the same color and brightness at any given time. A good tutorial can go a long way towards getting it right the first time. Good luck More on reddit.com

So, I’m buying more stuff, trying it out, and trying to figure it out. I have three BTF-LIGHTING WS2812B (RGB 5050SMD Individual Addressable 16.4FT 60Pixels/m 300Pixels). https://www.amazon.com/gp/product/B01CDTEH3Q/ref… More on forum.electromage.com

The depth of the shelf is 12 Inches ... the strips together, they're will be LED lights everywhere, even behind the cabinet. ... Did you get the tape already or do you know what you are getting ? Post a link for us. You mean "what if the splices are not long enough"? The clip is where the wires attach to the tape. The clip assembly would be a clip and a piece of wire. ... I found these below and wondered if those male pins would link together two of the connectors... More on doityourself.com
