With that kind of terrible efficiency, and the horrendous cost, what
exactly did engineers see in these things, at that time?? Ira.

I wonder if someday in the distant future, the google group "neoled" will
be full of stories about 7-segment LED displays selling for hundreds of
dollars each on Ebay.and even-more-expensive steampunk LED clocks.

Is there a datasheet for this LED? I am really interested in the current
draw. (The voltage is fixed, more or less, by the wavelength. So the
current will tell us something about the efficiency.) Jens

Yes, that $265 price is in 1969 dollars, the MV2 was insanely expensive
when it was released. The MV2 was not really usable as an indicator
though... it can only be seen in a darkened room. The only evidence I have
ever found of them being used was in scientific experiments in the late
1960s. I
many years. Not a very good LED but worked as
advertised.
Clock used CK8754 nixies and real TI 74141 driver chips.
