Got this one from B@rt maybe 15 years ago 18mm and still glowing strong. Super glued to Maglite reflector. UCL lens. Tail threads cut off (2 alkalines exploded in a 6D) epoxied in the head so tailcap threads in. Called it the Zero D Maglite
Would be interested in getting another sphere
you got it all right, but its an old version with manual switch collar. Need an old body M600 not the current DF (dual fuel) model that takes SF18650
