Wow! this is far more support than I'd dream. I am also completely content
with the moon in the ``full moon week'' when skiing, also with values 0.1
to below 0.30 lux.  But a research supporting my experience is wonderful.

Thank you so much!

(what the actual direct moon illuminance is, says my programme
planet, in a php script Illumination by the Moon, at e.g.
        URL: http://amper.ped.muni.cz/light/lun_illum.php
or better at a page Computation of ligthting-relevant values
        URL: http://svetlo.astro.cz/compute/
 )

with best regards,
 Jenik
