I haven't compared them side-by-side, but based on what I perceived, I would say that my e+lite is pretty dern close to my old Tikka. I would probably attribute this less to the difference in battery size and more to newer LED tech.

The e+lite does boast a "bright" or "boost" mode. However, what I have noticed (along with most reviews online) is that the boost mode fades back down to normal after a few minutes. Switching to normal for a bit and back to boost will get you the brighter light again. Still, it's annoying to have to do this. Then again, maybe that's the point -- if you need a light that is more permanently bright, get a different one. Like the Tikka XP, I own that one two and it is equally as awesome but in a different way.

peace.
