Hi Edmund,
Many thanks for posting the spectra of different light sources. Very useful, not only for enlarger usage, but also for choosing an LED for microscopy under-stage lighting. I made the mistake recently of buying a 6,000K or 7,000K wire ended LED, hoping to get something more blueish than a "warm white" but when I tried it, the light was a good blue, and very little use to me. I'd hoped for something a little "colder" than a Warm White LED. What I bought was a Maplin N83KG and very blue, despite being described as "white".
I've got a lot to learn... I'm pleased that they're now so cheap, and easily experimented with.
