Early Green & Red LEDs (Unknown Mfr.)  
Written by AnubisTTP on 2008-07-07  


These unusual early LEDs are constructed on a disk of gold covered in frosted epoxy. The example on the left contains a standard early red die, similar in brightness to a Monsanto MV1. The rightmost example is a rare early attempt at making a usable green LED. The amount of light produced by this early green LED is far dimmer than even the MV2, and can only be seen in a darkened room.


Two early LEDs of unknown manufacture, including a first generation green model. If you can identify these LEDs, please contact us.

Only in near darkness can a normal camera detect the light coming from this early green LED.

The epoxy molding process was not exactly a precision technique on these devices.
