This Radio Shack piece is an ordinary looking LED in a clear, T1 3/4 package. When lit up, it produces a narrow, yellowish-amber beam with good
brightness characteristics. It is uncomfortable to stare into directly.
Its color is a little oranger than most of the yellow models sampled above, but quite a bit more yellow than the yellowest orange model (the HP HLMP-DJ24) it was compared with. It could very easily be placed in the "yellow" category.
When shone at a distant target, it produces a distinctly square spot with a dark circle in the center. This pattern is typical of the very narrow-beam LEDs;
the beam in this one is probably only five or six degrees wide; not counting the much dimmer, slightly orangish outer ring. It's beam is a little too narrow to use in
things like keychain flashlights, so I'm not exactly certain these were made for.
