I read the following tutorial: http://popoklopsi.github.io/RaspberryPi-LedStrip/#!/ws2812
In the tutorial 1m of WS2812 led strip is used and it is stated, that its power supply needs a maximum of 3,6A. Now I want to do this with a 5m led strip, which has 30leds/m, which is a total of 150 leds. In the tutorial it is explained, that 1 led needs a maximum of 60mA. So I would have to buy a power supply with 5V and 9A. Is there anything like this, because I didn't find one or is this incorrect ?
Thanks in advance
