Description: 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.

  • 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
