Q: how much power will I need for 20m connected all together

Asked by Medichawk1 on 2019-11-24 12:14:11

SandyMan69 According to the documentation each 5m length contains 300 LEDs and each LED is 0.2w. So for 5m length you need 60w. So according to the documentation supplied with the item for your 20m of LEDs you will need a 240w power supply. HOWEVER that was from the supplied documentation, when I actually measure a 5m length with a Watts meter I find that it only consumes 22.5w! So with that value you will only need a 90w power adapter to light up you 20m length.
