Hi,

I'm planning on playing around with some LED lights (well a variation on neopixels..).. and I'm trying to workout the power supply that they would need.

Wattage: 0.3W/pixel
Working voltage: DC 5V
50pcs pixel per string

so.. from my googling....
amp = watt / volt

which means : .3/5 = 0.06
so each pixel draws 0.06 amps, right?

so 50*0.06 = 3amps..
and if I wanted to run 100 lights, I'd need 6 amps?

So a power supply that can give 5V and 6+amps should be good right?

Just want to make sure that I'm looking for the right thing...

Thanks!
