You can get the camlight handle from the return value that camlight returns or you can use findobj to retrieve the camlight handle. I have posted a code snippet example to explain the same:
surf(peaks) axis vis3d h = camlight('left'); for i = 1:20; camorbit(10,0) camlight(h,'left') pause(.1) end
l = findobj(gcf,'Type','Light')
Hope this Helps!!
