Picked up the new 2C ML25T at Walmart today. Brightness seems about the same as the previous generation but it is not likely you would notice the difference between 177 and 192 anyway.The new ML25T turns on high by default, a quick twist off and back on changes it to low. Mag lists a 7 hour run-time on high so output must diminish over time unlike the old model. The low run-time is listed as 72 hours and I assume it diminishes over time as well if it actually does run 3 days. The packaging is actually from the 177 lumen model but stickers were added to cover the old specs with the new ones.
I still think there is something to be said for flat 2 hour regulation of the 177 lumen version but the new model will probably get a better reception. The availability of the low mode and presumed change in regulation of the high mode should make this new model a much more viable emergency/car light.
Cool! Can't wait till these show up at a local walmart. I think the step down regulation is a good idea, especially for anyone running alkalines - the original 2 hr run time was too short. But now between the step down and the low mode battery life is much less of an issue. I hope at some point Mag will come out with a 2 mode 3 cell ML25 as well.
BTW not surprised about he brightness, I always thought the old ones were a bit underrated.
