Andrew...
I agree with your FAR references, Andrew, but in an article you wrote
entitled "Europa Nav Lights Using Luxeon Leds", page 11, (undated) you
have
two graphs. One is for theta = 0° and one is for theta = 90°. Both
graphs
are for alpha (x axis) versus candelas (y axis). You further define
candela
on the y axis as lumens/steradian.
If you have a subsequent article that clarifies or extends the data in
this
article I reference, I'd sure like to see it. The "Europa..." article is
the only one I could find.
I'll be happy to ****t you the preprint articles for Kitplanes this year
July, August, and September for your review and comment if you like. The
October, and final chapter, is a work in progress, but it only has details
on the power supply and nothing on the light distribution.
