there's plenty of lighting solutions where you can ski in front of you. lots of Super bright and efficient LEDs these days.
You can drive your car 65mph with headlights, you can relatively easily create an LED setup that can output just as much light as headlights and more with mail-order components (just simple electronics, no rocket science degree or top secret access to prototype LEDs needed).
That video is more just for the benefit of the camera and getting a cool visual rather than for the rider.
