Should work, though I suggest a lower lumen LED because the Fulton’s reflector is shallow and most of those lumens would be wasted and these lights are not intended for much heat.
I run my Fulton’s on 55 lumen Nite Ize LED’s - these are rated for 2 to 6 cells, so they will also work with D cells.
i also print various adapters.
renders alkaleaks obsolete!
btw my old angleheads have metal reflectors and bakelite retainers.
i have done a few hotwires with them.
newer ones may be plastic.
