This is a small, square LED in a flat, SMD-like package. It is the red version.
There is a metal plate on the bottom of the LED package for heat sinking purposes. This plate is electrically isolated from the anode (+) and cathode (-) connections.
The die (light-emitting chip) is not lensed, so the LED has a wider than usual viewing angle of 110°.
The estimated dominant wavelength (where you would point to on a color chart) of this LED is 625-630nm, which is a slightly orangish red.
Brightness measures 17,240mcd on a Meterman LM631 light meter.
Viewing angle is 110°.
Final reminder for today: Wider viewing angles always, always, ALWAYS equal lower mcd values.
Vf measured at 2.26 volts at 373mA.
