Soviet 3L341V LED

Description

The 3L341V is a de-facto example of a Soviet-made LED. Manufactured in 1989, the 3L341V appears to be 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, for implementations where a 0.1 microlumen LED just won't cut the mustard. Needless to say, you won't need special eye protection to handle them.

Soviet manufactured 3L341 LED. The included datasheet indicates that they emit no less than .15 microlumens, useful for implementations where a .1 microlumen LED just won't cut the mustard. The only way to damage your eyes by looking at one of these LED's requires accelerating it to ballistic velocities first.
