If you use your Googlefu and type in 'RC N3 torch' you should find some similarly priced items that may be a tad better than the tesco job. Depends if you want to send away for something or pop into tesco for it.
Saw these the other day, they are not very powerful; recommend you seach on Ebay, by typing in 250 lumen LED torch, or just LED torch and you will get shedfulls. I have bought a load of small 250 lumen Cree LED torches at £5 each. They last for ages and give a beam upto 200 feet. They also do a 1000 lumen for about £12 which allegedly goes up to 400 feet. You don't need much else.
Plod use a Cree LED 250 lumen which costs £44 and is no better than the cheapies except if you clout a hoodie with the plod one, it will hurt him much more !!!
Well, he did specifically ask about a torch. Maybe he's a slightly Damascene psychopath, I don't know. But there is a very practical consideration. A Maglite is wipe-clean. A tree root would probably do the job, but it would retain traces of DNA. Of course you could burn it, but in 2012 I think that we should be thinking in terms of sustainability and eco-friendliness.
