i defiantly recommend the energiser, i have quite allot of head torches being a carp angler, and a head tourch fiend, i have them ranging from very cheapy ones right up to some more of the most expensive petzal ones, and i can honestly say, hand on heart for the money, those energizer ones, are fantastic, i have the small one, which i think cost me 4 quid, and it has the switch at the top to turn it one way or the other for red or white, and i have the big brother to that, that you press the button for the different options, which is in my opinion, amazing for a tenner, i also have the alp kit head tourch, which if you like a green light, instead of a red light, say for tracking or you just like the glow of the green, its great, but you still can't beat the energizer, for the money.
hope that helps lads
