A flash light can be made from leds. The diference would be if it lights on a single strobe or in a continuous mode.
That is definetly a "ring" made of leds. If was used as a strobe or as a continuous light is hard to know. (But I suspect it is the second option)
A continuous light can be used on video.
But on a still photography you could try to gess reading the exif from the photo.
