Thanks scotroutes.
Just for info I have bought a Manta for my SiL but got it delivered here so I could look at it first 😉
It’s ok, no brighter than the gamma really but has a focusable beam which may/may not be useful. It has the batteries mounted behind the light so all the weight is at the front and no strap over the top but we’ve got three Gammas in this house and two of them have failed in the wiring which is necessary because the battery pack is at the back.
I’ve also bought the one linked above by stever which is crazy bright but quite a bit heavier (like double . . .) and takes the 18650 exploding batteries.
The FRA forum (mentioned in the thread above) seems to come out in favour of the Lenser H7. Anyone any experience of the H5?
