I am running a LS-4P flashed with WLED 0.14.0-b1 with a 5V 50W 10A power supply , driving a reel of WS2812B 5V LEDs with 300 LEDs in the strip. According to the data sheet this reel when run at 100% brightness , color white should pull 65W and 13A if the WLED limiter is turned off.
When I wired it up and ran it I took measurements. I found that at 100% brightness, no WLED limiter I measured a voltage drop of 2.93 volts and had visual indications of voltage drop , but it was only drawing 1.57A and 7.85W. I am not sure why this is happening unless the LS-4P has some kind of limiting built in. I have shared this with people on the WLED discord and they are equally puzzled.
I realize that I need power injection to make this run work properly, but I do not understand why it is drawing only 1.57A from a 10A power supply.
