That's good reading. Except sometimes I think those photography boys live in a 'light' world of their own--they lose me. You know what's fustrating? Remember when we used to buy a fluorescent grow light, most often there would be a glossy white page within the box with a beautifull full color chart printed on it? Not any more! And, here just the other day when I opened some pdf's on Sylvania, GE, Philips,etc. under the links for specs, charts and graphs to post here, not a single one had a color chart. Most were so generic, more suitable for elementary school reading. One of the links drew a blank page with a prompt on the bottom: "back to the top".
But now, on these same company websites, there is quite a bit of information on LED, including charts and graphs and so on. Maybe they're presenting an 'eye to the future' which I think is good. And maybe now is the time for us to get in on the 'ground floor' of LED, knowledge wise.
