I would like to light up my staircase with a 15meters strip of WS2812b (Neopixels) and control them through a particle photon.
If I use 30LEDs per meter strips, I will end up with 450LEDs. Taking into account that an LED will need max 60mA, that makes 27A*5V = 135Watts.
I am therefore planning to buy a 200Watts (220VAC in, 5V out) power supply such as [this one].
In order to have a better power distribution in the LEDs, I will connect the 5V at both sides of the strip.
Do you have some experience with a similar setup?
Is there something I might be missing or do wrong?
