Question 1

What makes an LED strip addressable?

Accepted Answer

Each LED carries its own tiny driver chip, so the controller can send a different color to every pixel down the line. A standard RGB strip only changes color as one continuous block.

Question 2

Which is better, WS2812B or WS2815?

Accepted Answer

WS2812B is cheap, widely supported, and runs at 5V. WS2815 uses 12V with a backup data line, so voltage drop over long runs is smaller and one dead pixel does not kill the rest.

Question 3

How many LEDs per meter should I pick?

Accepted Answer

Sixty per meter suits most desk and shelf lighting. Choose 144 per meter when the strip sits close to a diffuser and you want no visible dots, but expect higher current draw.

Question 4

Do I need a separate power supply?

Accepted Answer

Short runs can draw from a USB controller, but a full five-meter strip at full white needs a dedicated supply rated for the total amperage. Add power injection at the far end on long runs.

Question 5

Can an addressable strip be cut to length?

Accepted Answer

Yes, cut only on the marked copper pads between pixels, and keep the data arrow pointing away from the controller. Re-solder or use a clip connector so the data line stays continuous.
