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 port 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.

what is a steradian ??????
