well, if you're just walkin the dog and all, i'd say get TWO lights, one main light and a backup. The Fenix TK40 (runs on 8xAAs) would be a good light, hefty with multimodes so you can balance output and runtime. Then a second light (smaller of course) either holstered or in your pocket as a backup.
For the 2nd light, it depends on whether you'd like to retain commonality in cells (i.e. keep using AAs) or switch to something else. I will work on the assumption that you're going to stick to AAs.
The choice then is, would you like a single AA or double AA light? Single AAs are of course smaller but would have less runtime than a double AA.
So why not get THREE lights
your budget i think would support a Fenix TK40, Quark AA2 and Quark AA. All these lights are available at
4sevens (use "CPF8" for a discount) and i think that there is a
Fenix UK if customs duties are an issue.
If you do decide to order from the UK outlet, then the Quarks are no longer an option but Fenix has great AA and 2xAA lights as well.
Why get one if your budget lets you get 3? Get those, a load of eneloops and a charger and you're all set.
i just took a quick look at the UK site, the TK40 (124.95), LD10 (42.95) and LD20 (47.95) will add up to about 216 quid and there's free UK delivery
and batteries.
Hope this helps!
Oh and :welcome:
your wallet may not thank you though
EDIT: to check out the lights that i referred to above, you can search here and also on youtube by just typing "TK40 youtube" and a whole host of video reviews will pop up. Here is
one review to start you off.
