Calculating the Power Change of a Lightsaber Due to Colour

Luke Willcocks


This paper investigates the effect of different coloured lightsabers on their subsequent power output, by assuming that the lightsaber produces pure photonic energy as the name would suggest. It was found that the power output of a lightsaber increases with decreasing wavelength, causing the lightsabers of shorter wavelength to cut through a titanium blast door in a shorter time period. For example, the purple lightsaber was found to melt through the titanium door in 8.20 seconds in comparison to the red lightsabers 14.00 seconds, which shows the purple lightsaber to be the more powerful of the two.
