These color-changing LEDs take the work out of creating crazy, flashy, blinky... ness. Simply apply power and the LED will cycle through the RGB colorspace: no external controller necessary! These bright and festive LEDs make great decorations, LED "throwies", indicator lights, etc. Typical forward voltage is 2V.
These 5mm LEDs are of the "fast-changing" variety, meaning they fade-cycle very quickly through several colors and then flash-cycle through several more colors before starting all over again.
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Your description says that has a Vf of 2 volts. But at that voltage all it does is slowly vary the intensity of the red. If you read the data sheet it says Vdd is more like 4.5 volts ... at which voltage it actually makes colors and does neat stuff.
https://www.youtube.com/watch?v=4iFE9r0Aq-k&feature=youtube_gdata_player this contraption uses 2 sets of 4 in series. when in series they seem to have a neat interaction with each other.
Can these be featured in a product video? The descriptions seem to indicate different patterns (and not just different speeds), but the datasheets are all the same one, with the following timing graph (color representation): http://i.imgur.com/jZZpG.jpg
There's a new product post every Friday with product demonstrations. So check back tomorrow around noon EST.
Yeah, I just know the videos tend to be made pretty much before said Friday :) I'll keep an eye out, though :D
Check the homepage today, I have them in the video. We'll link the video back to the product pages later today.
As far as I can tell still not here. I'm trying to show someone at work what they look like.
OK found it.
Yep, caught it - great! :)
