I, recently, bought a mix of flashbulbs.
There are some press 25, 40, 50 and GE equivalent.
Some are transparent and some are blue, but there are 1 for type that are black (or very dark brown...), and I don't know for what task are they so.
What I' sure is that aren't used ones...
bye

| I'm guessing the black ones are infrared. GE for example made type #5R which have a coating that just allows the IR light to go through, giving you an "invisible" flash. |
