Homemade Flashlight Is Relatively Bright
Optics engineer Ralf Ottow built himself a flashlight. But not just any flashlight -- he built a 38-million-candlepower flashlight with a plasma mercury arc bulb. He calls it the Maxablaster. I call it bright as shit.
The Maxablaster creates a highly focused beam of light with a high UV content not so different from a star. So UV-filtering glass was added to block the potentially harmful raysâ€”though evidently this thing is still plenty bright enough to burn skin, as it has Ottow's on at least one occasion.
Sweet. And I thought last week's Wicked Torch was something. I'm going to make one and use it instead of candles for my mother-in-law's birthday cake. I'm not totally sure how old she is, but 38-million sounds close enough. True story, she used to date Methuselah's older brother.
