In case anyone else is curious, I asked Rob at Dinotte how could I tell if the Ultra 5 I just bought from REI was the 120L or 200L version. Here is his reponse:
The (200L) beam will be a little bit more narrow, but it’s much better overall on the road – even with the beam change. The light output changes by a factor of 1.3 and that has nothing to do with the beam change.
Take your light, hold it against the wall, (2 feet away) if there appears to be a square beam with a round circle inside and a small hole in the middle, you have the old style, otherwise you have the new. Hard to say what you have at this point.
Now, when shone on a wall, I don't notice a square beam or a darker hole in the middle, but I do notice a small, brighter circle within a larger, less bright circle. To those with the 200L version, does your light create the same brighter center circle beam a few feet from the wall?
Thanks a lot!
