Torches are mens toys
Well, don´t know to much about SE helicopters at night, haven´t done that kind of flights since Culdrose
but doing at least 1/3 of my actual flying with NVG.
I have four lights - with Smartphone - 5 lightsources with me.
a UK Penlight
Minilampe UK 2AAA Penlight eLED - Underwater Kinetics in a pocket as a spare an for refueling
a no name singe AAA battery LED-Light for start up, when instrument lightning gets dark due to power consumption of the starter and for normal walk around
a one blue LED keylight on a very thin cord with an automatic coil device, which is on my chest-pocket, always handy to have a look on the switches
and last, a modifed kneeboard, where I changed the white bulbs against blue LED (which I prefer against the green ones and they don´t distrurb the NVG either)
Works great for me.
The other "Zweibrüder" torches, Mini Mag lights and so on are collecting dust in my drawer, they were just to bulky or broke to easily (bulbs of the mini mag) or were to complicated to switch on (to much options and I don´t want to search for the "right" lightcolorswitch) ;-)
