I am talking about "flash" in the optical sense, rather than the memory sense.
I have an application where such a device would be very useful. I think that I have seen some as small gas-discharge tubes. I would expect that there may be some LED ones out there. Does anyone have suggestions for technical information sources (optical spectrum characteristics, life time, and such) and driving circuitry and sources? I am hoping to find something with a useful spectrum that extends from near-IR to blue.
Yes, I know that Google Is My Friend, but I am hoping that someone will be able to fill in some background information before I start the search process.
