true true!
one thing's for sure: with 10440's the iTP is the very brightest AAA flashlight i know of. Brighter than Tank E09 with 10440's. Much brighter. On the other hand, the Tank E09 has the better head for heat-sinking because it's made out of Aluminum and its mass unusually dimensioned:
Aluminum head Worm 5.400g (=5.400/13.100= ~41.22%)
versus
Titanium head A3 6.797g (=6.797/14.461= ~47.00%)
versus
Aluminum head E09 6.272g (=6.272/12.796= ~49.92%)
Whoever owns already the iTP A3 should be happy and not look further. For people with no AAA lights and looking for a best value, then the Tank E09 is really good choice. E09's form factor resembles more iTP A3 than Fenix LD01 or Fenix E05 imho.
