Thanks guys. I'm humbled by your compliments. I'm a pretty crude modder and have long way to go before I can make anything even approaching the quality of what some of you do. I try to document how I do things (to some extent) so that others can duplicate and/or build on my ideas.
I was under the impression that this Nichia emitter can handle up to 5 amps on copper. 3 amps looks like a pretty sweet spot on the curve. Djozz did some testing here. Did I screw up and misunderstand his thread? Here is a chart from his thread.
I think the jury is out on the CRI of these emitters. I'm not a good judge of it. All I can say is that I really like the tint and the apparent high CRI. To me it seems better CRI wise than the 219A. It emphasized reds a tad less. Seems more balanced to me.
