I had found the Lith-Ion/incan reference, or links to it anyway, several times already, but I always got a server error when I tried to follow the links. Last night I finally noticed the actual OP and I read through most of the first page. Now this is all making a LOT more sence. Now, all that I can say is thank you very much for your patience with me! Especially fivemega since he's told me the same exact thing 3 or 4 different times now and I have kept asking the same question over and over on different threads. Sorry about that, now I get it.
The 3.7V Strion has been recommended to me several times by several people, so I'm going to at least try it and see how it compairs. Since I have 2 lights, I can do a side by side comparison with them and see what I think of them. I suppose I could then take the 9V bulb out of my TL-3 and try it for comparison also, but at this point I'm thinking that I'll end up using either the 3.7 or 6V bulb. Most likely, if the difference is minimal, I'll leave at least one of the lights with a 6V bulb since I already have them. Looks like I'm going to end up needing to get one of those little organizers to keep track of everything.... LOL. I won't really have any use for any of these lights until October so at least I have a little time to set some $$ back for the batteries and such.
Thanks again,
Mark
