Lovely older 620 film camera. It has this interesting flash bulb system. Iím aware that LEDs canít generate the lumens as rapidly or nearly as brightly as these flashbulbs. However, I wonder if I can replace the bulb with an LED I can turn on with a button to provide a short duration light that will help with indoor photography. Has anyone tried such a thing? Plenty of room in the handle. Anyway, if youíre seen this tried please let me know!
