>>2239612fenix HM65R with a red light instead of the secondary white light, varusteleka sells this version and I believe the same model is also sold in the UK as the HM65R shadowmaster
>takes 18650s, has usb-c charging port so you don't even have to put them on a separate charger>sturdy as fuck and decently waterproof>red light goes from very low to bright enough to see a good 100ft or so down the trail>white light goes bright enough to melt a hole in your pants if you turn it to max>has good battery charge indicator so you don't forget to charge it before going out and will easily last an entire night of normal use>separate red and white buttons and remembers previous brightness setting when you turn it back on so you don't accidentally blind yourselfI keep my old nitecore NU-25 around as a lightweight backup, but as far as I'm concerned this thing is pretty much perfect
