ahhh, now i know i can talk with authority! hahaha
As some of you know i do alot of underground exploration,old WW2 sites and mines and caves, bunkers etc, and an essential part of kit is good sturdy reliable lighting that can adapt to situations.
The best i have found that i personally use, is, well not the cheapest but it will never let you down!
Petzl myo 5 (belt) it runs from 4*C cell batteries in a pouch with can be located in clothing (batteries run better warm) as well as having 5 LED with excellent 3 power settings. as well as a switchable halogen/zenon 100ft Spot lamp, all very light and very durable.
As the price is around £50 im sure not of norm interest! unless you want something like that!
My recommendation would be a Petzl Tikka, or Tactikka.
Both are 3-5 LED and have power settings, ie , dull, flash, medium and snow blindness! haha
The range starts at around £15 and worth every penny, light and waterproof! and you can get them in olive and camo strap!
myo belt 5
tactikka (led flippable red filter as well)
hope this is of some help, you can get cheaper jap imports, but alas you get what you pay for!
also, have a check
updates soon of more pillboxes, and emplacements, and underground with me in the czech republic:)
