Did anyone do runtime tests on the newer SF U2A (especially on CR123A)? I can't find them anywhere.
SF states at their website "At the high setting the U2 will put out two hours of tactical level light (50+ lumens from an LED source) with a total runtime of three hours. At the lowest setting it will run for 175 hours."
175 hours on low? Is that regulated the whole time? What's the lumen output of the lowest setting? (175 hours is pretty impressive) What about the other levels between, how long will it run then?
I found only runtime graphs with 18650 on an older luxeon SF U2..
Thanks.
