The first lamp I had made it myself using a 1949 BSA Bantam D1 motorcycle headlight 6v, about 2 candle power, bright as a Toc H lamp. The lamp in the pic I got back in 1983 it's a Clulite, got an old 50's army rucksack with steel frame, welded a plate at the bottom to hold a car battery, bloody well nearly killed my back first night out with the weight of the battery and Rabbits, soon got a 12v motorcycle battery instead. Still got the same Clulite lamp 32 yrs old, will be using it again come Sept.
