Homebrew flashlight adds a new star to the galaxy

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.

  1. The Oracle says:

    You can buy those huge flashlights that are basically a car headlight tied to a battery for around $20 and they say 15 million candlepower. Just focus it a bit more and you’ve got 38 million. (Since candlepower is light per unit area).
