Re: Conversion Program for Lumens/Lux/Candle Power ?
There is not.
Comparing the Lumen ratings to Candlepower ratings is not possible. Even comparing ratings from within some brand's own model range is misleading - especially where CP is concerned.
SureFire is the only brand that is open and consistant about their Lumen ratings.
The trouble is that unless you have a SureFire, the other SureFires Lumens are hard to judge until you know the type of beam distribution that SureFire usually go for.
Therefore Lumen rating are difficult to use alone - some form of light distribution rating (beam angles?) and colour temperature ratings are needed to find out more about the beam (as well as how it changes over the runtime of the batteries.)
