LED's can be manufactured to a wide variety of specifications, and that's
what makes them so versatile.
A couple of years ago someone on the darkroom newsgroup was working on an
LED light source for enlarger heads, utilizing clusters of high-intensity
LED's. I don't know what happened to the project, but at the time a lot of
people were really excited about the technology and the initial results
showed a lot of promise.
