Is there a chart/table of equations around to convert candle power to lumens etc etc so I can compare different manufacturers light please??

Bagman,

Do a quick search for Candlepower vs. Lumens, I'm sure you'll find an answer to your question.

Just to elaborate a particle or two, my understanding is that candlepower is related to focused beams of light, whereas lumens are not limited to beamed light output--therefore, it is very difficult to convert between the two.

I'll save you some time: given a candlepower measurement and a lumens measurement and no other information (which is the way it always is), the two are not convertible from one to the other. Ya, bummer!

You're welcome

And if I could be even more unhelpful: Since different manufacturers seem to measure candlepower and different distances, even comparing candlepower to candlepower is very often so misleading as to be nearly useless. And hey, a simple candlepower reading won't tell you what the beam is like: a beam highly-focused into a little laser-like point will be very bright, but may or may not be as useful for you as a beam that puts out more light overall, but is less focused and thus has a lower candlepower rating.
