Yes, a good back up light like the Fenix E01 would be a great idea!
Bottom line is: they don't really need any handheld light. Just give 'em headlights and spare batteries and that's about it. People have been climbing the Everest and the K2 with nothing but Petzl headlights for decades. Only geeks and inexperienced excursionists bring a truckload of useless and cumbersome "toys" to camping trips.
Be aware that this is Flashlight Forum, and not a serious outdoor message board. I've already heard the most absurd recommendations from people with zero trekking experience around here.
The input has been wonderful everyone. It really is appreciated.
The trip is not about moving around long distances in the dark, in fact far from it. They will probably end up staynig very near where they were working and use them for no more than 50ft of walking from the tents and back, if that.
Thanks hyperloop. I told them to get some Fenix lights instead and a headstrap for them. I figure instead of loading up with lights, may as well get a few decent ones and make do with that. Plus they will bring them back as they will be decent kit, assuming no loss or damage. The 3D will be going but I suspect it will only the TerraLux Luxeon upgraded one, no Malkoff as I have not been approached to get it back.
I have seen the Nitecore D10 R2 as well, was considering that would be very good also. The lumen chasing behaviour you see is only because this would be their first high power flashlight so they may as well get the brightest they can, despite the difference being an amount not discernable to the average eye.
