I also see makers advertise run time based on moonlight modes, and lumens and throw based upon that 30 second burst....and turbo runtimes being the short burst at max COMBINED with the REMAINING runtime on high, etc.
If the standard was going to have a shot at being representative, as the great unwashed out there don't know a lumen from a lux from a cp, etc, a run time chart might be a bit of a reach, conceptually. Adding a simple set of MATCHED values, for example lumens at the 30 second, mid point and end point of the run times claimed, would be reasonably easy to understand, and reasonably easy to obtain.
They are already measuring the run time, and, the lumens to see when they have dropped to 10% anyway. All that would be needed is to publish the lumens and throw at those three points in the claimed run time. So, sure, its 10% of the initial claimed lumen burst, but, most people don't know that...and showing that they'd have a 1/3 to a 1/10 of the max out put will be enlightening for most users.
(I'd also like the ANSI throw #'s revised to reflect reality relative to the ridiculous 0.25 lux)
The run time is a big deal to guys on patrol for example, especially if using disposable cells. If they NEED a certian output, which of course means a proportional throw distance...they want to KNOW that after 30 seconds, the light can't hit that distance anymore.
