G.E. MAZDA Photoflash Lamp No. 75
Filled with oxygen and crumpled squares of extremely thin magnesium foil, the GE Mazda Type 75 was the largest flashbulb
ever manufactured. It was initially developed to be used as a source of light for night time aerial photography during world war II. Rated at
180,000 lumen seconds of light, one 75 flashbulb is powerful enough to light up a football field.
They are now very rare, but still used for cave photography, where a lot of light is needed.
