Lines: 11 In-reply-to: murray@uctvax's message of 10 Jul 90 11:28:34 GMT The one I bought from Ledtronics (?) has a color that is a sort of 'powder' blue. The light was bright enough, just not a very intense blue. A look at its spectral output curve showed no output in the UV. I was hoping to use it as a sensor in the UV (most LEDs will work as low power photoelectric sensors). I don't have the spec sheet here with me, but I believe the 'blue' end cutoff was at about 470nm. I might mention that these toys aren't cheap. The one I bought cost $15.
