And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
Wonder what the light intensity is at the bottom. Looks like UV-A LEDs, not a lot of output. UV-A is known to penetrate a few cm of water, but disinfection/bleaching is square law dependent. Net: pretty blue lights, probably not very effective. But an actual kill study with an innoculate could be convincing.
