I LOVE these little comparisons and stats.
What's funny to me is that if the
vs. Destroyer beam is supposed to be hotter/more powerful, then the color is aaaaaaaall wrong. Blue light is ca. 420 nm wavelength, and red has ca. 710 nm wavelength. The shorter the wavelength, the more energy being given off. Blue is hotter.
So, either the color is wrong or the beam
really is weaker. Since the spiral ray was a red, yellow and orange-ish colored, I think we can assume that Toho screwed up on the color if that beam was SUPPOSED to be more powerful than the original blue one.
