They're just brighter and lasery versions of what already exists (Parks Sabers, Master Replicas, etc.). They obviously added a (mediocre) lightsaber effect on top of the fight parts. The actual blade glow shown in the same ad looks quite different.

Which just goes to show that fictional lightsabers are ridiculously and impractically bright, and that the effect generally used, even when done well, is bunk (but looks good).
