I anxiously await any replies as well.
The TT-2L is my current favorite relatively cheap light/relatively small light for general overall use. I think the LED output is just about perfect for my particular uses and gives a huge flood. The incand is fine, but would definately like more throw. Not sure how possible/likely this would be with the LED holes in the reflector but I guess if enough folks show interest... who knows.
So, even if you are just interested in mods for this great all-purpose light, state your interest here.
