Absolutely wonderful! Thanks for putting in the time and effort both to run the tests and to graph it out so cleanly.

Not being an engineer, I'm still a bit lost on the y-axis of the graph; is that radiant flux? Can the y-axes be superimposed, or are they relative units? If they're a function of distance, at what distance were they measured?

Thanks again, and can't wait to see how your led setup looks once you get around to it. I'm also a blue-y kind of guy for lighting, so this is very useful stuff.
