Infrared LEDs are used for remote controls (they're the little LED in the part you point at your TV) and 'night-vision' cameras, and these little blue guys are high powered ones! They are 940nm wavelength, which is what nearly all devices listen to.
Positive LED terminal for the IR emitter. Adafruit identifies the part as IR333-A; the Everlight IR333-A datasheet package drawing labels lead 1 as Anode.
Negative LED terminal for the IR emitter. The Everlight IR333-A datasheet package drawing labels lead 2 as Cathode.
