How to use Espruino with WS2812 arrays? (Like RGB-123)

I got the 1600000 from the video, http://www.youtube.com/watch?v=RBHP4xDCR­k4
that was shown during the kickstarter . I wish I'd found the tutorial when I was doing this (so I could have copy-pasted the code), but I'd have still thought I needed 1600000, since the video was using the same arrays I'm using, while the tutorial that stated 3200000 used the WS2811's not WS2812's.
