1. Whenever I see a flashy box in a store containing a light with a huge candlepower rating alleged on the side of the box, I’m very skeptical that it’s a good light.
  2. Think about it: 3 million candlepower? Exactly what are we talking about here?
  3. A beam, to help you, must travel through dark and often cut through mist and illuminate an object far away, with minimum of distortion, such as a dark area in the middle of the beam.
  4. This is very different from making a great rather indiscriminate glow in the dark.
