basically to have a somewhat wider range of wavelengths
Also looking at trying these three emitters as a triple from luxeonstar.com
These specific model numbers are pretty close in electrical demand, so ought to work in series
(I want to try series first, before tangling with trying to wire up three in parallel, as my work gets sloppy at small scales, a bit shaky)
(Xref, I asked about this idea a while back at Host suggestions for the 20mm Noctigon Triple - #7 by hank — just getting around to trying it)
Red - 75 lm (LXML-PD01-0040)
Red-Orange - 90 lm (LXML-PH01-0050)
Amber - 77 lm (LXML-PL01-0040)
I’m not sure how much these overlap the eye’s receptors, but I think the result might be better color perception than with a monochrome red source.
