Is it possible to damage a LED by connecting it directly to a 9V battery?

The site linked below has done a nice write up on various "purple" LEDs, measuring
and comparing the wavelengths, dispersion angles, etc... between various manufacturers
and suppliers.
It seems that the lower 395nm wavelength  (listed at the above ebay website) is a purer
purple, which makes sense because safe "blacklight UV-C" is actually 356nm. And everyone
knows blacklights are purple. (But stay away from 245nm UV-B, it will damage your eyes)
Lots of good info here...

Hope this info is helpful.

Very cool site, I found out a lot about the wavelengths and which are dangerous when researching some Lee filters last winter when I made a sun lamp after being disappointed with the quality of the store bought. It was funny because I'd look through the Lee Gel filter and it would look like summer outside! Was a great mood elevator for the winter blahs.

Led's and those little tantalum caps were our favorite form of entertainment at work when I was building ham radio crap.  Straight to a 12 volt high amp supply the mobile line tech used.  Basically firecrackers.  Have good safety glasses..
