These LEDs have a metal package sealed with a lens cap that delivers narrow directivity. Hermetically sealed packages are reliable even in highly humid environments.

These LEDs are hermetically sealed in a metal package and can be used in highly humid environments.

These are standard package LEDs potted with clear resin. A reflector (cavity) is provided on the metal stem (TO-46) to enhance the light extraction efficiency.

These resin-potted package LEDs use a metal stem having no reflector and are suitable for applications requiring a small diameter light spot.

These plastic-molded package LEDs can be easily inserted into place on PC boards and are available at a lower cost than metal stem types.
