I recently purchased one of these LED strips. Now I have read all about how these are notoriously known for drawing a lot of current from its power supply so I bought one of these power converters thinking I would have more than enough power to sufficiently supply the strip. The converter is wired to a 12v power source.
However, when I set all of the LEDs in the strip to full white at max brightness I see a reddening of the LEDs as you get closer to the end of the strip, indicating to me that the blue and green diodes seem to be dimming and therefore not receiving enough power.
I then measured the current using a multimeter and discovered that the strip was only drawing around 4.5 amps when in reality it should be drawing around 9 amps. This was calculated based off of 60mA per LED at full brightness from Adafruit's guide to powering the WS2812B's and other research I've done.
In essence, the LED Strip is only drawing 4.5 amps when it should be drawing nearly 9. Any ideas on why this might be? I am also controlling the LEDs using an Arduino Uno.
