I sent the following email response to this topic this morning, but it seems
to have disappeared into the Ethernet, so I'm sending it again. I included
details of one of the Australian distributors and the price in the earlier
email. Just in case that was the reason my email wasn't posted on
Birding-aus, I've since removed those details.

I recently purchased a hand-held Fenix TK40, which is advertised by the
retailer for use in on-ground search and rescue operations. 

It is powered by eight AA batteries.  It has four power settings:  630
lumens (operates for about 2 hrs at this level), 277 lumens (about 6 hrs),
93 lumens (about 20 hrs), 13 lumens (about 150 hrs). It also has strobe
lighting. On the highest setting, the length of the beam was easily over 200
m, and it could have been as much as 300 m. 

I've only used it on one recent field trip, involving 4 consecutive nights
of spotlighting, but I was quite impressed with it and was more than
adequate for spotlighting purposes. I found it was adequate to spotlight
(for nocturnal birds) using the 277 lumens setting. You can use the high
power settings for spotlighting, but use the lower settings for writing
notes, sorting equipment, walking back to the car etc. But if you are also
wearing a head torch (which I was), that might not be such a big deal.

It's quite light and compact, weighing about 300 g (with batteries), is
about 210 mm in length & flashlight diameter of 61 mm, and comes with a
shoulder strap. 

I think it adequately serves my purpose for nocturnal survey work.
