I'm sure this is already on here, but I couldn't find it. I'm looking for the equations relating lux, candela, lumen output, and meters (distance). I'm trying to do a quick and dirty brightness comparison to determine if I have the right product.
I have two lights from the same company, one a thrower (rated 1000lm) and one a weaponlight (rated 950lm). Now, I realize the beam profiles are very different, but the thrower *seems* to be putting out a heck of a lot more light than the weaponlight, which looks closer to (but still brighter than) a 300-some lm light with a similar beam profile. I've tried contacting the company once, but I got no response.
Using the rated candela, lumens, and whatnot, I would like to determine the distance from a wall at which the two flashlights (thrower, and weaponlight) would produce the same lux. If the weaponlight is obviously dimmer, I can bring my results to the company in question (since both lights are manufactured by them), and hopefully get a replacement. If there's no noticeable difference, I have no more problems. :twothumbs
Thanks!
