Super bright red, green, blue, and white LEDs, in narrow and wide angles, in packs of 10.
These have become really affordable in the last few years, though you might not know it from the prices at Radio Shack. We picked up these very nice LEDs and are passing the savings on to our customers. The specifications above are about all the documentation we have on these LEDs. I will say that we had to raise the standard ballast resistor values for the pilot lights we put on our breadboards in my classes, as these LEDs were just too bright.
All of the LEDs below are T1/34 (5mm) with .100″ lead spacing.
The wide angle models have lower ratings just because the light is spread out, not because the chips are emitting less light. White LEDs are usually now rated in lumens which is more accurate view of how much total light the LED puts out.
