Thank youSofirn are well known in the flashlight circles. They manufacture some lights designed by the flashlight community (mainly on BudgetLightForum) including the LT1 lantern.
The SP40 is kind of a default recommendation for a non flashlight person wanting a budget headlight, particularly over on reddit's r/flashlight.
They are available on Amazon UK, but not at the sale price, 4.5 stars with 200+ reviews.
If you still have the maps and access to green light, could you see if it works better? @Herman30 has a point with the wavelength. Green light is used by the military primarily for map reading.
I've only ever known of red light to be used (in vehicles, buildings, OPs etc), never heard of or seen Green being recommended for use. Apart from anything else it wouldn't work (at least on the UK issued maps) - all of the wood blocks would vanish, and on the 1:25k mapping, so would the public rights of way. I think you would be stuffed! UK military maps are almost identical to the normal OS maps, just issued unfolded without covers, with slightly different info in the margins, and with an overlay of military specific information (generally in red, blue, and brown) providing rules and regulations around training areas (e.g. out of bounds, no dig areas, range boundaries etc), and picking out pylons and power lines for navigational use (mainly for aircraft). Possibly some overseas maps might lend themselves better to the use of coloured light, but most of the military ones that i have come across variously use red and green in them whatever, so white light is the way to go. In many theaters aerial photography is issued as the mapping, with certain features picked out, and a grid overlaid. Used sufficiently dimly, white doesn't have an appreciable impact on night vision in my experience.
Sorry OP - this post is taking things a little away from the thread!
In Finnish defence forces troup transport vehicles (PASI) there were two inside lights: red and blue. But they did not teach us about which to use and when. I did my conscript time in 1986, donn´t know about current equipment.I've only ever known of red light to be used (in vehicles, buildings, OPs etc), never heard of or seen Green being recommended for use.
