Monsanto MV1 LED

Monsanto MV1 light emitting diode, new old stock, tested with minor shelf wear. The Monsanto MV1, released in 1969, is considered by most LED collectors to be the world's first production visible light emitting diode. The MV1 is a very dim light source, and is barely visible under normal indoor lighting.

Fairchild FLV102 LED

Rare early Fairchild FLV102 LED emitters, new old stock. Like many other early diodes, the FLV-102 uses a modified transistor package as the base of its construction. The leadframe and base are identical to a standard T-106 ceramic transistor; the only difference in the package is the use of a diffuse red epoxy blob, through which the LED light exits the device. The light emitted by the FLV-102, a feeble 1mcd, is easily drowned out by average incandescent lighting.

Nichia NSHU550 LED

Nichia NSHU550, lot of three, new old stock. The Nichia NSHU550E is the first commercially available UV-LED, featuring a 370nm peak wavelength and 1mW output. These are a historiclly significant part and very hard to find.

Note: these LEDs output a shorter wavelength of UV than commonly available 5mm epoxy LEDs, and as such they should NOT BE VIEWED WITH THE NAKED EYE! Looking at these LEDs while powered can cause permanent vison damage.

Lamina Atlas Green LED

Lamina Atlas single cavity green LED, new old stock, tested and working. The Lamina Atlas is an extremely high quality LED with gold plated contacts and four spiral contact dies in a central cavity. Unlike most other high-flux LEDs that use plastic lenses and packages, the Atlas uses an optically pure glass lens to cover the dies. This is the same model of LED that was used in the Iron Man costume for the Iron Man movies; the cheap Chinese LED stars that flood Ebay are not in the same league as these devices!

Tiny Red Axial LED

These are extremely small axial red LED's in a clear epoxy package with gold leads. These are about 2mm in diameter, note the green spot of paint on one lead, which indicates the cathode. We have no idea who the manufacturer is for this LED, but they are consistent in package style and internal construction to a Monsanto or General Instrument MV50.
