The “MaxBlaster” is a 38 million candle power flashlight created by Dutch optics engineer Ralf Ottow. By taking apart a commercial flashlight, inserting a mercury arc bulb, and adding a custom designed reflector, the beam is as powerful as a miniature star when seeing it from a distance. Pretty amazing design, just don’t look at it directly. Check out how it was built at the link below.
