Adafruit 1138-4m

It means you can control the color and brightness of every single LED on the strip independently. Instead of the whole strip changing color at once, you can create complex patterns, gradients, and animations by programming each pixel separately.

The white base acts as a reflector, which helps the light appear brighter and more vibrant compared to strips with a black or clear base. It also ensures better color reproduction, making the colors look cleaner and more accurate.

Yes, these strips are designed to be cut at specific intervals, usually marked by copper pads. You can trim them to fit your project's exact dimensions, though you will need to solder new connections if you want to use the cut-off pieces elsewhere.

Because this strip has 60 LEDs per meter, it draws a significant amount of power at full brightness. You will need a 5V DC power supply capable of providing enough amperage to handle the total load, typically requiring a dedicated power injection point at the end of the strip to prevent voltage drop.

This specific model is not rated for outdoor or wet environments. It is intended for indoor use, such as accent lighting, decorative displays, or hobbyist projects where it will remain dry.
