}Ok- now that blue LEDs are under control again...

}from the data sheet- one showing spectral frequency vs relative output
}(peak @ 650 nm), the other showing luminosity vs. current - which was
}spec'ed at 3000 millicandellas at 20 ma. forward current.  No other data
}was given.  Physically, it was a T-1 package, nothing unusual. 
}   Now that is a very high-output LED.  Does anyone know who makes such
}an item?  The fellow representing the product said he had to import them- 
}whatever that means.  But he would not tell me who made them.  Not being 
}a whiz on opto stuff, I hereby submit the matter to the collective con-
}sciousness of the net.

I suspect that the units were microcandelas.  Product literature people are
not that careful, as a usual thing.  Why don't you check with the mfgr.
