Do the both measure the same thing?  How do you compare the two?  Is there a formula to convert one to the other?

They measure the same thing. Multiply Lumens by .08 to get Candlepower.

.....I would think..(it hurts when i do)...the bulb and reflector around it might have some bearing also.?

I suspect the 1 million candlepower number was made up by the light company's marketing dept.

Maybe,its a Vector VC127Y.Just looked at the carton it says, 1 million cp,and blinds the crap outta anyone its pointed at.~

Here's what Laser Products, the makers of Sure-Fire Tactical lights, has to say about it.

The lumen is a measure of the amount of light, as opposed to the intensity of light. A typical 75 watt incandescent light bulb has an output of 1080 lumens. At a distance of ten feet, this light bulb would provide uniform illumination of slighty less than one lumen per square foot.

Another measure of light is the Candlepower, which is not a measure of the amount of light but a measure of the intensity at a given point in a  foucsed beam. Because such a measure produces impressively large numbers, it is often quoted by other manufacturers. For example, the above 75 watt bulb equipped with a reflector  could be rated, under certain conditions, as producing over 2 million candlepower. Since this rating is highly dependent uopn which point within a given beam is being measured, candlepower ratings can be very unrealistic and, therefore, certainly not a true measure of the amount of light being produced.


Get all that? [;)]

Thanks for those answers,I was wondering this myself.[;)]I fully understand.

Damn I love this site.

What I love is the single hollywood candle that has a several billion candle power.  You have all seen it, an actor will light a single candle in a dark cave or room and it looks like a sunny day in Miami!  I need several of those candles for when SHTF!

You guys forgot about LUX measurements.

remember frying stuff w/ a magnifying glass?...  that's some candlepower (at the point of focus).

Funny though, 1 candle will burn leaves, bugs, etc. just as well as a 30,000,000 candlepower focus of a magnifying glass.  In fact, probably better!
