Soviet 3L341V  
Written by Accutron on 2017-02-08  

The 3L341V is the de facto example of a Soviet-made LED. Manufactured in 1989, the 3L341V appears to be of standard GaP green chemistry, but is encased in a 1970s-style metal can package with gold leads. The included datasheet indicates that they emit no less than 0.15 microlumens Needless to say, you won't need special eye protection to handle them.

The 3L341V was distributed in cartons of 100 pieces. The large white print on the top reads as 'Indicators' in Russian.
