New 2x 26650 body sleeves are now 3D printed with a solid top and brass nut for battery positive contact. Single Cell sleeves are PVC with open end. Made to convert D cell Maglites to use 26650 Li-ion cells.
Short sleeves are for single cell use (2.5") and longer ones (5") convert 2 D cell mag. Shorty tail spring is needed for this conversion.
Spring option: You will need to modify the tail spring to fit a pair of 26650s in a 2D cell Maglite, so purchase of the shorty spring is recommended.
Magnets option: 2pc 8mm x 2mm These are used to make contact between a pair of 26650 batteries if your cells are not button top and don't already make contact with each other end to end. Most cells are magnetic on the + end however not all are. If yours are not and alternative is to place the magnets on the top and put a dab of epoxy around the edge of them to hold in place.
Lens option: Many dropin bulbs including some of A.S.Flashlights will work fine with only the factory lens. The high temp lens is more transparent so output will be greater with this. If your using the 3x XHP-50 bulb its highly recommended that you also use the high temp lens.
