- Powering a WS2812B strip 1 answer
I am currently trying to light up a staircase at my house. I bought two 5M reels of WS2812b 5V LED strips on AliExpress and some solderless connectors... I am planning on putting about 40cm on each step, which would in total be exactly 6 meters of LEDs. One thing I am struggling with is choosing a correct power supply for my needs. The seller says that the strip needs 18 watts per meter.. Which would make 18*6=108W in total. Do I need a power supply that has exactly 108w or can it be more (or less)?? Also I am connecting each step in parallel with the next one. Does this change anything? And If I choose a power supply and then use the LEDs on half power (or less), does that matter? Thanks in advance!
PS. My wiring will be the same as on this image: https://cdn.instructables.com/FOD/XLFY/IGTY8XVX/FODXLFYIGTY8XVX.MEDIUM.jpg
