NeoPixel Digital RGB Power Requirements

[anakinjay]

Hello,
I have a project that calls for 6 meters of the NeoPixel Digital RGB LED strips powered by an arduino mega. The description lists 5v / 10a as enough to run 4 meters... can anyone tell me how much power I would need for 6 meters?

Here's a link to the product so you don't have to go searching for it:

3.3A per meter is the max (all leds on at full intensity). So for 6 meters, that would be 21A max. Typical usage running patterns and such is usually about half that, so 10A might work if your patterns are not too intense. 12 or 15A would be a more conservative estimate.
