ah, good clarification there, when you talk about a bit more throw, what sort of distances did you have in mind? And are you adamant about sticking to the AA cells? The more dedicated throwers that i know of use either CR/RCR123s or 18650s.
I recently got a Ultrafire WF-500 xenon which is an amazingly bright light, lit up the garden pathway 12 floors down and highlighted everything, could pick out scraps of litter, leaves etc and this was in conditions of quite a fair bit of ambient light. The light runs on 2x18650s.
But for AA throwers, not too sure, you might wish to check out
selfbuilt's awesome 2xAA roundup and
light-reviews.com to get a better idea of what's out there. Click 'reviews' on light-review.com then 'AA/14500' in the pop down and then again on 'lux' to sort by lux numbers.
in selfbuilt's round up, the Olight T25, Jet I Pro EX v2.0 and Fenix Tk20 were remarked to have good throw and the light i mentioned earlier Romisen RC N3 II Q5 also has a nice mention there.
On light-reviews, the Fenix TK20 has the 4th highest lux numbers (which i take to mean for throw purposes) with the Fenix TK40 (which is a giant 8xAA light) holding the no. 1 spot, the Olight P100A2 is 3rd and 2nd is the LED Lenser P6 (which i am unfamiliar with but i do own the P14 and P5 which throw pretty well too)
I assume you have a headlamp already, but if you dont, get a zebralight h501 for trekkin in and to keep your hands free (may be essential for SAR), it runs off a single AA and also has 3 modes.
hope this is of some use, cheers.
