A bright (500W) light source sits at the focal point of a convex mirror. Directly opposite is another mirror with a match at its focus. The heat and light from the lamp will be refocused right where the match is causing it to light.

  • As long as your mirror has a short focal length. It should work reasonably well as long as you are careful with your alignment. These mirrors have about a 4" focal length. Although this lamp is 500W, I have a dimmer on it, so it's actually only putting out about 250W.

  • Interesting experiment, I found one of the 7 inch beauty mirrors and wow lots of power.
