Someone forgot to mention if they were incandescent (ant??) fluorescant, carbon arc, LED and whatever else I cant think of now.
AC incandescant lamps --
When I was on submarine we had this 17 year old report aboard. Leonard tried to be real salty to impress us "old salts" (on board a couple years and all of 23 and 24). So when he was sent to get a lite bulb I asked him if it was fluorescent or indancescent - he goes back to his chief (Max was a real salt - he had WW II combat patrol pins)
Leanard comes back "the kind you screw in"
I ask him AC or DC? Off he goes to see Max his chief.
Next thing I know is here is Max with Leonard in tow
")&^$#@^ Bentler give the kid a lite bulb and stop screwing around I need it for that *&)%$% droplight"
Leonard got his lightbulb.
