notos&w,
As I have examined it in the dark I find it is better than I thought.
I compared it with a TT-1L, a TT-2L, and a SL TL-2LED.
Although the TT-1L had a tighter spot, the mod was as good overall, even if not quite so far for throw.
The TT-2L was not nearly as bright in its LED mode as the mod, and that is not surprising. I have considered that plenty of light to walk trails in the dark. Of course, in the Xenon mode the TT-2L was clearly superior for distance.
As expected, the TL-2LED was a no contest winner.
The main thing I wanted the mod for was to have a good LED light in a very small size. It fulfills that purpose. If I want more light I will carry one of my other lights.
I think of it more as a parking lot security light than any thing else. I'll have to go to Walmart, and after checking with the security, see how it does in a parking lot.
I notice the S&W part of your user name. Have you forgiven S&W, and do you use many of their guns? I have several. I think they got back on track with the sale to the employees, if I am correct in who bought it. The Brits were never very logical in the gun control area.
Is there any advantage in using AA lithiums over the alkalines in the 2AA twistie? Except for cold weather I don't think of any advantage.
Have a good evening,
Jerry
