Ok, I got the light two days ago. I am not a good reviewer and have no way to test things but here are some thoughts.
Price wise, the original came without a battery, new one comes with a slightly bigger 21700 that can be charged with the supplied usb cable. The handle (body) reflects this size increase and run time is stated to be about 25% longer. When I got the package the batt. checked at 3.54 volts and took about 4 hrs to get to full charge, quite a long time. Outputs are stated to be the same as the old one. I have seen consumer testing that indicated the lumens are slightly higher than stated and candelas as much as 10% higher than stated? I don't know, I just use these lights to get my crazy Lab retreiver out at night to see the wildlife.
On the first night there was a full moon. I could put light on a hillside 400 yards away that already had 1/4 lux on it from the full moon so that is pretty good. The next night there were 4 deer at a little over 100 yards and they were easily identifiable, you could see the expression on their face, ha.
One small change is that it now has two springs for the battery, front and rear. The battery status indicator works good and matches the reading on my meter. The side mounted mode button is hard to find in the dark with gloves but the rear (on-off) button can be activated even with mittens.
The light is just what I wanted and works good for me. If you have specific questions I will try to answer them if I can. CPF member Timothybil has used one for a couple years, you may want to check his posts.
Cheers
