Green, if you have an ML25 in LED format you pretty much already know what a 125 is like beam-wise. With it's supplied battery it's got an output similar (according to Maglite) as a generation 1 and with alkalines it runs a bit brighter according to Maglite so it would be similar to the new generation ML25. The big difference is the runtime versus the ML25 but even that isn't quite as stark of a difference.
I do not know what year it came out but mine has 2015 on the box. The 2016 ML25 3 cell for example was stated to run 17 hours at 177 lumens on 3 alkys. The 125 is stated to run 25 hours at 193 lumens on the same batteries. Candela on the 3 cell ML25 was in the 12,000 range where the 125 is stated to be 18500+ so aside from size of light difference the 125 has better numbers on paper.
I ran some tests on both 2 and 3 cell LED ML25's back in 016 and found the 2 cell to be rock solid regulated until the batteries were well depleted and then you had about 45 minites to find new fuel. Just over 2 hours with no decline, which folks scoffed at back then. But after two hours it was still at 100% output, which was something new for Maglite. The 3 cell ran for the stated 17 hours easily with about a 50% decline in output. Again you had useable light for another 45 minutes.
Now is the ML125 as well regulated as those ML25's? My guess is no they are not since it came out before the maxi-minimag ML25's.
The ML125 numbers stated by Maglite on the box it came in.
Now regarding beam pix of it's adjustability? They were not that stark of a difference and I know my cameras well enough to know it would be very difficult to get photographs to show what you see in real life. Perhaps at some point I'll make a point to do that.
I think the reason I am still a fan of Maglite is the same reason I'm still a fan of the Bendix coaster break bicycle wheel. A fairly simple idea that worked very well at it's inception and over the years has remained fairly simple to operate while minor improvements have not caused it to become unreliable. While the world has gone and gotten itself in a dam hurry so all kinds of newfangled gadgets like bikes with hydraulic brakes and 44 cogs can propel turtle shell helmet wearing people in spandex billboards on their destination as fast as they can muster, I prefer to meander on my fat spoke 2 speed bike truck at a pace that gets me there eventually. But the designs and concepts range between the 1940's and 1960's using tried and true components my geat grandchildren will enjoy (Lord willing and the A-bomb don't melt it).
My pop told me after I was grown that when I was 4 years old I tried to turn my tricycle into a 2 wheeler. Apparently minus a magic adapter that the postal service still to this day has not delivered it would have worked. I do remember having all kinds of ideas growing up that would someday happen. Like balancing on the rear wheels of a wheel chair, or doing nifty tricks with my skateboard that took hours, even days or weeks to accomplish. I'd eventually show my idea to someone who would duplicate it in 10 minutes. It was heartbreaking as a kid but as an adult I tend to appreciate the value of the saying "first one through the wall gets bloodied". A fellow who made brass shell casings for the US government and a former sheriff put their heads together and with some help from others too built what would become the undisputed king of flashlights for quite some time. While others easily employ new ideas and a host of "hydraulic brake wheels" I enjoy the simple upgrades of the tried and true inventions of the past. Like an internal hi/lo gear coaster break wheel or the simple genious of a Maglite product.

You peddle along and kick back slightly on the brake to change gears. Start in low and when you gain some speed you can opt for a high gear.
The bike was built by my buddy Fred Clark at Retro Cruisers using a Worksman bicycle as a platform with a few tweaks to tube angles and lengths. The cogs are a 22 tooth rear and 36 tooth front that I picked out. The pedals and grips are new old stock from the 1970's and the bell on the handle bar is new old stock from the 80's when beach cruisers were all the rage. The paint is Corvette red acrylic.
I will always be a big PK fan but I was a Tony Maglica fan before that.
