This is the reply from the company from whom I bought my 50 count 12v rgb smart pixels from. I have the lor 16 channel pixel controller v4 and I also have pix con 16 pixel controller and I also have 4 channel pixel controller. I don't think these boards have the ability to change the amps built in to them.I believe it has to be done in the hard ware utility is this right new to rgb ??? thank you
don't have a video on this, but our 12v 12mm pixels are 0.06amps per bulb, if you are running the full white. The amps change based on the color the bulb is projecting. So if you plan on 3amps for a 50 count strand you’ll be safe. (50 x 0.06amps = 3amps)
The calculate watts: amps x voltage = watts
In the case of the 50 count strand: 3amps x 12v = 36 watts. Again, this assumes you are running full white on the lights which would be your worse case scenario.
Not to complicate this, but most rgb controllers have the ability to reduce the output of the strands. So you could set the controller to 50% output, which would reduce you to 1.5amps, yet, the brightness of the lights will still be good enough for your display. This would let you reduce the amount of power supplies you need to run your lights.
