Thanks, at last an understandable explanation of lumens for the NON-Engineers. My son is an E.E. and he could not explain to my satisfaction.

i am looking for a very bright flashlight thats not going to be too large… maybe the length of a dvd case or smaller. i have no preferance on whether it is recharagable or not. i would not like to have too many modes on it; 3 modes at the most. high battery life would be a plus and i would like led rather than xenon… i know i sound picky but i need some help… thank you for any response

I’ve seen some reviews sites use lux as a measurement. How does lux relate to lumens and candlepower?

[...] value. 3) Brighter the better, no doubt about it, however as mentioned in our other article “Lumens vs. Candlepower” you will find that lumens is only a measure of total light output and not a measure of beam [...]

If you look at most of the high-end flashlights on the market, you will find that they all use lumens as their units of output. The amount of lumens is a fixed number while the candlepower can be grossly inflated by simply concentrating the beam by adjusting the focus. We recommend that you compare the output of flashlights by using their rated lumens. Thanks for the comment!

Which is better to determine the usefulness of a flashlight?
