RRT-3 is considerably bigger, heavier, older UI, flood-throw 346 meters throw, 5 lumen low, and has more weight to absorb the heat, so stays on turbo longer.
TM11 is compact, lightweight, newer easier to use side switch, pure flood 286 meters of throw, roughly 10 mins turbo, 25% more run time of 1:15' versus RRT-3's 1 hour.
Btw, if I'm not wrong, the TM11 not only has cheaper box packaging than the Jetbeam's magnetic flap box, but the annodising on the TM is pure matt finish, where the Jetbeam is semi-matt semi-polished finish; co-incidentally, the Zebralight SC600 compact 1x18650 side switch 750 lumens pure flooder and 145 meters short throw also comes in a cheap cardboard box, and a pure cheap looking matt finish, worse - no ss bezel.
Personally, I only got TM flooder, because I already have RRT-3 SST-50 pure thrower which throws some 400 meters, give or take; thus RRT-3 Triple XM-L not enuff advancement for me to buy, plus in between the other two.
Lightjunction gives 12% cpf discounts, while Bugoutgearusa gives 15% discounts, and both sell both Jetbeam and Nitecore...
