According to this article, you really can't convert candlepower to lumens because candlepower is a measure of intensity of a spot of light, and lumens is a measure of light in all directions. So that helps explain what you're seeing, Randy.
But now matter how you measure it, there's a LOT of game playing and exaggeration going on by the folks that sell light sources, and it's even more common today with the advent of LEDs. I've had good luck with Surefire, Streamlight, and the economy brand Coast, but near as I can tell, only Streamlight makes a hand held spotlight.
Near as I can figure, a lot of it boils down to the specific LED they're using. There are generations of them, and within a given generation, the LEDs of a given type all have pretty much the same output. Find a trusted manufacturer so you get good construction that will deliver rated output, then wait a year for the output to double and do it all over again...![]()
While I agree that you can’t really directly compare candela to lumens, they do give a formula to do it. 12.57/1. No idea how they arrived at that or who “they” were. LOL
