No, they values quoted on the Wikipedia page are for conventional xenon/gas discharge flashes. LED flashes have a much longer duration - try photographing a moving subject, you will see that they're basically unable to freeze motion and are only sufficient for illumination purposes.

EDIT: I just took a video at 240fps of an LED flash (sony xperia, as my n900 is sitting somewhere in a drawer). I counted ~36 frames, so ~150ms for the main flash duration.
