On the USB PropStick which I just purchased, there is a VERY bright blue "serial receive indicator LED" (surface mount) which can be seen at all angles.
This LED type is nifty and I would like to buy some. Can anyone tell me the light specifications of the LED? Like...
Name of the specific color of blue
Wavelength (nm)
Mcd
Full viewing angle in degrees
Or the manufacturer/part number?

The Blue LEDs that we use are Mouser part number 638-19217BHCN1P23 . All of the other surface mount LEDs we use are from Lite-On, with part numbers that start with "LTST-C191". They are all 20 mA LEDs, which is relatively bright. They do not have lenses, so the viewing angle is over 120 degrees, which is why they can easily be seen from any angle.
