I want to power 8-10m WS2812b RGB Led Stripes (see Adafruit Neopixel 60 leds/m).
(I will start at 8m and maybe extend to nearly 12m.)
These are 5V LEDs, most of the LED drivers are 12V. I want full closed (waterproof) PSU.
But only some open frame versions have 100W at 5V. Most are 12V or higher.
Is it better to use 2 x 40W at 5V to power the LEDs from both ends (cut ‘+’ in the middle).
Or should I use 12V 100W and transform it down to 2 x 5.xV at a high ampere level?
