Before anything, I want to say that I am a complete noob in electricity, so please treat this as close to ELI5 as possible, thank you!I am currently making a shopping list for an APA102 LED light strip with 144 LED's/p/m and I am getting 3m of it. Now, my main problem is powering that beast.By my calculations, (42W * 3m) / 5V = 25.2A, if that is correct, that seems like an insane amount of power for such a strip, and any power supply I could find that was > 15A is just a barebones transformer.They have listed that 42W/m is the maximum power draw, which feels very unrealistic. I've read that the listed wattage is sometimes almost 2x the actual max draw, does that mean I should be calculating at 21W/m?It is almost impossible to find any 25A power supplies, so maybe there is an option where I could use a higher voltage power supply and connect it differently to the strips, for example, at 12V, I would only need a 10.5A power supply for 126W.Thank you in advance! via /r/DIY http://ift.tt/2nOf6Zu
