Dive light type II

My KG-tube dive light was by and by too big, I built myself after the well-known net construction manuals with a Gel Batterie (accumulator) and China "Maglite" a cable lamp . Inspiration can be found en masse at bei Dive Light or as always at Lothar Seveke. Since it also should be inexpensive, finds one mirror lamp "OSRAM DECOSTAR IRC" use. New purchased materials about 30 .
