I don’t remember exactly, but it couldn’t have been much more than ¼ Amp (running the demo software), or my power supply current limit would have kicked in. So that gives you an order of magnitude answer… They were also brighter than I expected.
A quick google shows this web page:
http://www.aliexpress.com/product-fm/516056341-WS-2801-IC-rgb-LED-pixel-light-12mm-wholesalers.html
Which implies 60mA per LED; that would be 1.2A for all of them all on.
Well, looking under a magnifying glass I can just make out on the top of the PCB “SJ-1515ICRGB” and googling turns up:

Hopefully the pinout is the same…
I just picked mine up, only to find out that there isn’t even a pinout for this product… There are 4 wires between LEDs (Red, Green Blue White) but 3 pin connectors on each end. To make things more confusing, the white wire “T"s to the connector and just a bare wire on each end. Any thoughts?
I have not used them, but some people have thought their prices seemed a bit high. Download their simple software, CAD it up, it gives you a price quote, click “order” and away you go…
I’m surprised SparkFun is doing it again, after all the negative comments from kill-joy sour-pusses…
Last year I purposely didn’t try to get in on the free day, because I feel fortunate enough that I can buy what I need. After reading some comments by people who were going to try to get something that they couldn’t other wise afford, I thought I’d make more room for them. But heck, the $10 credit for each year you have been a customer, I’ll jump on that, since it appears that not taking advantage of that doesn’t make more $ available for others who might need it more :–)
I agree with Quazar; jumpers to connect the LEDs in series would make this more convenient. I’m not sure why Sparkfun bothered to post a schematic and not board dimensions; the schematic is just (3) LEDs :–) But locations of the mounting holes would be very nice so I won’t have to measure and assume I did a good enough job…

Looks like the github links above need updating… for example, I believe the home page should be:
